| 1 | Effect of Deficit Irrigation on the Growth, Water Use Characteristics and Yield of Cotton in Arid Northwest China显示文摘Water shortage is a key constraint to sustainable agricultural production in Xinjiang, Northwest China. To enhance the use efficiency of valuable irrigation water resources, a 2-year experiment(2010–2011) was conducted to quantify the response of cotton(Gossypium hirsutum L.) growth and yield to different degrees of deficit irrigation(DI) regimes; to determine the effects of DI on the characteristics of water use for cotton, seasonal water use, available soil water in the root zone, soil water depletion, evapotranspiration(ET)-based water use efficiency and irrigation-based water use efficiency, and to determine the best DI regime for optimal water-saving and yield output. The plots were irrigated at 100%(100ET), 85%(85ET), 70%(70ET), 55%(55ET) and 45%(45ET) of the regional ET of cotton in northern Xinjiang. The effect of DI irrigation on water use characteristics was evaluated by analyzing available soil water and soil water depletion in the root zone along with water use efficiencies of cotton. The study showed that the growth, water use characteristics and yield of cotton varied with irrigation regime. Seasonal ET and seed cotton yield were linearly correlated with irrigation amount. The second-order polynomial equation best approximated water-yield relationship of cotton in the study area.Cotton yield response factor was 0.65, suggesting limited water conditions were suitable for cotton cultivation. Economic evaluation of DI treatments confirmed that the yield loss was less than 10% under 70 ET and 85 ET, which was acceptable for greater sustainability.The results suggested that proper DI schemes were necessary for sustainable cotton production in the region. While irrigation at 85 ET was safe for high cotton yield, irrigation at 70 ET was a viable alternative under limited irrigation water availability. | YANG Chuanjie LUO Yi SUN Lin WU Na | 2015 | Pedosphere2015，25，6： | 17 |
| 2 | Effect of roadway turnings on gas explosion propagation characteristics in coal mines显示文摘In order to reveal the effect of turnings on explosion propagation, experiments were performed in three different pipes (single bend, U-shaped pipe and Z-shaped pipe). Flame and pressure transducers were used to track the velocity at the explosion front. When the pipes were filled with methane, the explosion strength was significantly enhanced due to the turbulence induced by increasing the number of turnings, while the flame speed (S f) and peak overpressure (DP max) increased dramatically. In addition, the strength of the explosion increased in violence as a function of the number of turnings. However, when the bend was without methane, the turnings weakened the strength of the explosion compared with the ordinary pipe, shown by the decrease in the values of DP max and S f . In addition, the propagation characteristics in a U-shaped pipe were similar to those in a Z-shaped pipe and the values of DP max and S f were also close. The results show that the explosion propagation characteristics largely depend on gas distribution in the pipes and the number of turnings. The different directions of the turnings had no effect. | Zhu Chuanjie Lin Baiquan Ye Qing Zhai Cheng | 2011 | Mining Science and Technology2011，21，3： | 12 |
| 3 | Effect of variation in gas distribution on explosion propagation characteristics in coal mines显示文摘In order to investigate the effect of variation in the distribution of gas on explosion propagation characteristics in coal mines, experiments were carried out in two different channels with variation in gas concentration and geometry. Flame and pressure transducers were used to track the explosion front velocity. The flame speed (Sf) showed a slight downward trend while the methane concentration varied from 10% to 3% in the experimental channel. The peak overpressure (Pmax) dropped dramatically when compared with normal conditions. As well, the values of Pmax and Sf decreased when the methane concentration dropped from 8% to 6%. The flame speed in the channel, connected to a cylinder with a length varying from 0.5 to 2 m, was greater than that in the normal channel. The peak overpressure was also higher than that under normal conditions because of a higher flame speed and stronger pressure piling up. The values of Pmax and Sf increased with an increase in cylinder length. The research results indicate that damage caused by explosions can be reduced by decreasing the gas concentration, which should be immediately detected in roadways with large cross-sections because of the possibility of greater destruction caused by more serious explosions. | ZHU Chuanjie | 2010 | Mining Science and Technology2010，20，4： | 11 |
| 4 | A numerical simulation of the influence initial temperature has on the propagation characteristics of, and safe distance from, a gas explosion显示文摘A model roadway with a cross-sectional area of 80 mm 80 mm and a length of 100 m was used to estimate the overpressure, the temperature, the density, and the combustion rate during an explosion. Auto-ReaGas software was used for the calculations and the initial temperatures were 248, 268, 308, or 328 K. The methaneair mixture had a fuel concentration of 9.5% and the tunnel had a filling ratio of 10%. The results show that the safe distance necessary to avoid harm from the shock wave increases with increasing initial temperature. The distance where the peak overpressure begins to rise, and where the maximum value occurs, increases as the initial temperature increases. These are almost linear functions of the initial temperature. At locations before shock wave attenuation has occurred increasing the initial temperature linearly increases the maximum temperature at each point following along the tunnel. At the same time, the peak overpressure, the maximum density, and the maximum combustion rate decrease linearly. How-ever, after the shock wave has attenuated the attenuation extent of the peak overpressure decreases with an increase in initial temperature. The influence of the initial temperature on the explosion propagation depends on the combined effects of inhibiting and enhancing factors. The research results can provide a theoretical guidance for gas explosion disaster relief and treatment in underground coal mines. | Jiang Bingyou Lin Baiquan Shi Shulei Zhu Chuanjie tiu Qian Zhai Cheng | 2012 | International Journal of Mining Science and Technology2012，22，3： | 10 |
| 5 | Study on 'fracturing-sealing' integration technology based on high-energy gas fracturing in single seam with high gas and low air permeability显示文摘To improve the gas extraction efficiency of single seam with high gas and low air permeability,we developed the'fracturing-sealing'integration technology,and carried out the engineering experiment in the3305 Tunliu mine.In the experiment,coal seams can achieve the aim of antireflection effect through the following process:First,project main cracks with the high energy pulse jet.Second,break the coal body by delaying the propellant blasting.Next,destroy the dense structure of the hard coal body,and form loose slit rings around the holes.Finally,seal the boreholes with the'strong-weak-strong'pressurized sealing technology.The results are as follows:The average concentration of gas extraction increases from8.3%to 39.5%.The average discharge of gas extraction increases from 0.02 to 0.10 m^3/min.The tunneling speeds up from 49.5 to 130 m/month.And the permeability of coal seams improves nearly tenfold.Under the same conditions,the technology is much more efficient in depressurization and antireflection than common methods.In other words,it will provide a more effective way for the gas extraction of single seam with high gas and low air permeability. | Zhang Chao Lin Baiquan Zhou Yan Zhai Cheng Zhu Chuanjie | 2013 | International Journal of Mining Science and Technology2013，23，6： | 10 |
| 6 | An analytical biomarker for treatment of patients with recurrent B-ALL after remission induced by infusion of anti-CD19 chimeric antigen receptor T(CAR-T) cells显示文摘Anti-CD19 chimeric antigen receptor-modified T(CAR-T-19) cells have emerged as a powerful targeted immunotherapy for B-cell lineage acute lymphoblastic leukemia with a remarkable clinical response in recent trials. Nonetheless, few data are available on the subsequent clinical monitoring and treatment of the patients, especially those with disease recurrence after CAR-T-19 cell infusion. Here, we analyzed three patients who survived after our phase I clinical trial and who were studied by means of biomarkers reflecting persistence of CAR-T-19 cells in vivo and predictive factors directing further treatment. One patient achieved 9-week sustained complete remission and subsequently received an allogeneic hematopoietic stem cell transplant. Another patient who showed relapse after 20 weeks without detectable leukemia in the cerebrospinal fluid after CAR-T-19 cell treatment was able to achieve a morphological remission under the influence of stand-alone low-dose chemotherapeutic agents. The third patient gradually developed extensive extramedullary involvement in tissues with scarce immune-cell infiltration during a long period of hematopoietic remission after CAR-T-19 cell therapy. Long-term and discontinuous increases in serum cytokines(mainly interleukin 6 and C-reactive protein) were identified in two patients(Nos. 1 and 6) even though only a low copy number of CAR molecules could be detected in their peripheral blood. This finding was suggestive of persistent functional activity of CAR-T-19 cells. Combined analyses of laboratory biomarkers with their clinical manifestations before and after salvage treatment showed that the persistent immunosurveillance mediated by CAR-T-19 cells would inevitably potentiate the leukemia-killing effectiveness of subsequent chemotherapy in patients who showed relapse after CAR-T-19-induced remission. | Yajing Zhang Wenying Zhang Hanren Dai Yao Wang Fengxia Shi Chunmeng Wang Yelei Guo Yang Liu Meixia Chen Kaichao Feng Yan Zhang Chuanjie Liu Qingming Yang Suxia Li Weidong Han | 2016 | Science China(Life Sciences)2016，59，4： | 6 |
| 7 | The Mechanism of Asphalt Modification by Crumb Rubber显示文摘To investigate the mechanism of asphalt modification by crumb rubber,the interactions between FCC slurry and rubber particles were evaluated at different temperatures and time.The rules of the change in mass of SARA composition in FCC slurry were obtained before and after its interaction with rubber particles,which showed that crumb rubber not only absorbed saturates and aromatics but also resins.Asphaltenes promoted the desulfurization or degradation of crumb rubber during the interaction between asphalt and crumb rubber. | Zhang Xiaoying Xu Chuanjie | 2012 | China Petroleum Processing & Petrochemical Technology2012，14，3： | 5 |
| 8 | Gas–solid interface charge characterisation techniques for HVDC GIS/GIL insulators显示文摘Surface charge accumulation on the spacers is one of the key issues restraining the development of HVDC GIS/GIL.The precise measurement of surface charge properties provides the basis for further study of the surface charge transport mechanism as well as the charge-induced flashover mechanism under DC voltage.In this study,the authors discuss their perspective on the current status,development needs and potential developing orientation of surface charge characterisation techniques.Different surface potential measurement methods and charge inversion algorithms are reviewed regarding the previous studies and future research needs.Drawbacks and outlooks of surface charge measurement techniques are also discussed with the background of laboratory experiment results and on-site measurements.It is hopefully that this study can serve as a useful guide reference for researchers within the same research field.More importantly,it is authors’hope that this study can inspire some novel ideas for readers into developing of more accurate and scientific interface charge characterisation techniques. | Lei Zhang Chuanjie Lin Chuanyang Li Simone Vincenzo Suraci Geng Chen Uwe Riechert Tohid Shahsavarian Masayuki Hikita Youping Tu Zhousheng Zhang Davide Fabiani Jinliang He | 2020 | High Voltage2020，5，2： | 4 |
| 9 | A systems dynamic model of a coal-based city with multiple adaptive scenarios: A case study of Ordos, China显示文摘Cities based on coal resources have increasingly important social and economic roles in China. Their strategies for sustainable development, however, urgently need to be improved, which represents a huge challenge. Most observers believe that the continued progress of these cities relies on the optimization of scientific adaptive management in which social, economic, and ecological factors are incorporated. A systems perspective that combines policies, management priorities, and long-term policy impacts needs to be applied. To date, however, such an approach has not been adopted, which means it is difficult to implement adaptive management at the regional scale. In this study, we used various situations to develop a multiple adaptive scenario system dynamics model. We then simulated a range of policy scenarios, with Ordos in the Inner Mongolia Autonomous Region as a case study. Simulation results showed that the current strategy is not sustainable and predicted that the system would exceed the environmental capacity, with risks of resource exhaustion and urban decline in 2025–2035. Five critical policy variables, including the urban population carrying capacity, rates of water consumption and water recycling, and expansion of urban land cover, were identified during sensitivity analysis. We developed and compared six socio-economic scenarios. The urban area, represented by the urban population density, seemed to transition through five different stages, namely natural growth, rapid growth, stable oscillation, fading, and rebalancing. Our scenarios suggested that different policies had different roles through each stage. The water use efficiency management policy had a comprehensive far-reaching influence on the system behavior; land urbanization management functions dominated at the start, and population capacity management was a major control in the mid-term. Our results showed that the water recycling policy and the urban population carrying capacity were extremely important, and both should be reinforced and evaluated by the local governments. | LIU XiaoQian PEI Tao ZHOU ChengHu DU YunYan MA Ting XIE ChuanJie XU Jun | 2018 | Science China Earth Sciences2018，61，3： | 3 |
| 10 | Mutation of the PHYTOENE DESATURASE 3 gene causes yellowish-white petals in Brassica napus显示文摘Oilseed rape (Brassica napus) with yellow flowers is an attractive ornamental landscape plant during the flowering period,and the development of different petal colors has become a breeding objective.Although yellowish flower color is a common variant observed in field-grown oilseed rape,the genetics behind this variation remains unclear.We obtained a yellowish-white flower (ywf) mutant from Zhongshuang 9 (ZS9) by ethyl methanesulfonate mutagenesis (EMS) treatment.Compared with ZS9,ywf exhibited a lower carotenoid content with a reduced and defective chromoplast ultrastructure in the petals.Genetic analysis revealed that the yellowish-white trait was controlled by a single recessive gene.Using bulked-segregant analysis sequencing (BSA-seq) and kompetitive allele-specific PCR(KASP),we performed map-based cloning of the ywf locus on chromosome A08 and found that ywf harbored a C-to-T substitution in the coding region,resulting in a premature translation termination.YWF,encoding phytoene desaturase 3 (PDS3),was highly expressed in oilseed rape petals and involved in carotenoid biosynthesis.Pathway enrichment analysis of the transcriptome profiles from ZS9 and ywf indicated the carotenoid biosynthesis pathway to be highly enriched.Further analyses of differentially expressed genes and carotenoid components revealed that the truncated Bna A08.PDS3 resulted in decreased carotenoid biosynthesis in the mutant.These results contribute to an understanding of the carotenoid biosynthesis pathway and manipulation of flower-color variation in B.napus. | Chuanji Zhao Luqman Bin Safdar Meili Xie Meijuan Shi Zhixue Dong Li Yang Xiaohui Cheng Yueying Liu Zetao Bai Yang Xiang Chaobo Tong Junyan Huang Lijiang Liu Shengyi Liu | 2021 | The Crop Journal2021，9，5： | 3 |

| 13 | Two soybean homologues of TERMINAL FLOWER 1 control flowering time under long day conditions显示文摘Flowering time is a key agronomic trait that directly affect the adaptation and yield of soybean.After whole genome duplications,about 75%of genes being represented by multiple copies in soybean.There are four TERMINAL FLOWER 1(TFL1)genes in soybean,and the TFL1b(Dt1)has been characterized as the determinant of stem growth habit.The function of other TFL1 homologs in soybean is still unclear.Here,we generated knockout mutants by CRISPR/Cas9 genome editing technology and found that the tfl1c/tfl1d double mutants flowered significantly earlier than wild-type plants.We investigated that TFL1c and TFL1d could physically interact with the b ZIP transcription factor FDc1 and bind to the promoter of APETALA1a(AP1a).RNA-seq and q RT-PCR analyses indicated that TFL1c and TFL1d repressed the expressions of the four AP1 homologs and delayed the flowering time in soybean.The two genes play important roles in the regulation of flowering time in soybean and mainly act as the flowering inhibitors under long-day conditions.Our results identify novel components in the flowering-time regulation network of soybean and will be invaluable for molecular breeding of improved soybean yield. | Lingshuang Wang Chun Lin Bohui Li Tong Su Shichen Li Haiyang Li Fanglei He Chuanjie Gou Zheng Chen Yanan Wang Jun Qin Baohui Liu Fanjiang Kong Lin Yue Sijia Lu Chao Fang | 2023 | The Crop Journal2023，11，3： | 3 |
| 14 | Association between fluid-attenuated inversion recovery vascular hyperintensity and outcome varies with different lesion patterns in patients with intravenous thrombolysis显示文摘Background and purpose To evaluate relationship between fluid-attenuated inversion recovery vascular hyperintensity(FVH)after intravenous thrombolysis and outcomes in different lesion patterns on diffusion-weighted imaging(DWI).Methods Patients with severe internal carotid or intracranial artery stenosis who received intravenous thrombolysis from March 2012 to April 2019 were analysed.They were divided into four groups by DWI lesion patterns:border-zone infarct(BZ group),multiple lesions infarct(ML group),large territory infarct(LT group),and single cortical or subcortical lesion infarct(SL group).Logistic regression was performed to identify risk factors for outcome(unfavourable outcome,modified Rankin Scale(mRS)≥2;poor outcome,mRS≥3).Results Finally,203 participants(63.3±10.2 years old;BZ group,n=72;ML group,n=64;LT group,n=37;SL group,n=30)from 1190 patient cohorts were analysed.After adjusting for confounding factors,FVH(+)was associated with unfavourable outcome in total group(OR 3.02;95%CI 1.49 to 6.13;p=0.002),BZ group(OR 4.22;95%CI 1.25 to 14.25;p=0.021)and ML group(OR 5.44;95%CI 1.41 to 20.92;p=0.014)patients.FVH(+)was associated with poor outcome in total group(OR 2.25;95%CI 1.01 to 4.97;p=0.046),BZ group(OR 5.52;95%CI 0.98 to 31.07;p=0.053)and ML group(OR 4.09;95%CI 1.04 to 16.16;p=0.045)patients,which was marginal significance.FVH(+)was not associated with unfavourable or poor outcome in LT and SL groups.Conclusion This study suggests that association between FVH and outcome varies with different lesion patterns on DWI.The presence of FVH after intravenous thrombolysis may help to identify patients who require close observations in the hospitalisation in patients with border-zone and multiple lesion infarcts. | Erling Wang Chuanjie Wu Dandan Yang Xihai Zhao Jie Zhao Hong Chang Qi Yang | 2021 | Stroke & Vascular Neurology2021，6，3： | 3 |
| 15 | Surface Charging Phenomena on HVDC Spacers for Compressed SF_(6) Insulation and Charge Tailoring Strategies显示文摘Surface flashover of spacers is a key factor limiting the application of HVDC GIS/GIL,while the charge accumula-tion on the surface of the spacer could have a potential adverse effect on the surface flashover voltage.This paper discusses the laws regarding distribution patterns of surface charges and the related mechanisms.The field-dependent property is discussed in detail to comprehensively illustrate the charge transport mecha-nism and explain the research differences regarding different surface charge patterns obtained by previous researchers.In addition,the main surface charge control methods for epoxy resin are summarized and discussed.The potential research directions of charge control methods and key points in manufacturing of spacers used in HVDC GIS/GIL are also explored. | Chuanyang Li Yuan Xu Chuanjie Lin Geng Chen Youping Tu Yao Zhou Zhipeng Lei Tao Han Simone Vincenzo Suraci Jian Wang Weidong Liu M.Tariq Nazir Shun He Andrea Cavallini Giovanni Mazzanti Davide Fabiani Jinliang He | 2020 | CSEE Journal of Power and Energy Systems2020，6，1： | 3 |
| 16 | Effect of high-voltage thermal breakdown on pore characteristics of coal显示文摘High-voltage thermal breakdown has great potential application in permeability enhancement of coal seam. The characteristics of the breakdown channel, coal element, porosity and microscopic coal petrography of coal under high-voltage electric load were experimentally studied. The coal interior left apparent tracks due to electric current burning with high temperature. The percentage of C, O, Al, Fe, and Si had slightly decreased, while the content of element N increased obviously. Low-pressure nitrogen gas adsorption(LP-N_2GA) and mercury intrusion analysis showed that coal porosity increased. The increases of micropores and mesopores are beneficial to promotion of the ability of gas storage, and the increase of macropores could enhance the gas seepage and migration. The results of scanning electron microscope(SEM) show that there are many exogenous fractures in coal, which is also beneficial to gas seepage and migration. The results lay a theoretical foundation for application of high-voltage thermal breakdown in coal mines. | Zhu Chuanjie Lu Ximiao Gao Zishan Yan Fazhi Guo Chang Zhang Xiangliang | 2017 | International Journal of Mining Science and Technology2017，27，6： | 2 |
| 17 | De novo design of future rapeseed crops:Challenges and opportunities显示文摘To address the global demand for rapeseed while considering farmers’profit,we face the challenges of making a quantum leap in seed yield and,at the same time,reducing yield loss due to biotic and abiotic stresses.We also face the challenge of efficiently applying new transformative biotechnology tools such as gene editing and breeding by genome design to increase rapeseed productivity and profitability.In this Perspective,we review advances in research on the physiological and genetic bases of both stress factorsaffected yield stability and seed yield potential,focusing on source–sink relationships and allocation of photosynthetic assimilates to vegetative growth and seed development.We propose research directions and highlight the role of plant architecture in the relative contributions of the root system,leaves,and pods to seed yield.We call for de novo design of new rapeseed crops.We review trait variation in existing germplasm and biotechnologies available for crop design.Finally,we discuss opportunities to apply fundamental knowledge and key germplasm to rapeseed production and propose an ideotype for de novo design of future rapeseed cultivars. | Shengyi Liu Harsh Raman Yang Xiang Chuanji Zhao Junyan Huang Yuanyuan Zhang | 2022 | The Crop Journal2022，10，3： | 2 |
| 18 | Effect of Plasticizer Poly(Ethylene Glycol)on the Crystallization Properties of Stereocomplex-Type Poly(Lactide Acid)显示文摘The effects of the plasticizer poly(ethylene glycol)(PEG) on crystallization properties of equimolar poly(L-lactide)(PLLA)/poly(D-lactide)(PDLA) blends were investigated. Formation of the stereocomplex-type poly(lactide acid)(sc-PLA) crystallites was confirmed by Wide-angle X-ray diffraction(WAXD) and differential scanning calorimetry(DSC) analyses. Sc-PLA crystallites without any homochiral poly(lactide acid)(hc-PLA) formed, as the result of the incorporation of the plasticizer PEG(more than or equal to 10%(wt)) at a processing temperature(240 ℃). Moreover, when the MW of PEG reached 1 000 g × mol–1, the crystallizability of stereocomplex crystallites was the best. Isothermal crystallization kinetics further revealed that PEG could accelerate the crystallization rate of sc-PLA, with the optimum crystallization kinetic parameters being obtained at 10%(wt) PEG. Several crystallization kinetics equations were applied to describe the effect of PEG on the crystallization behavior of sc-PLA. The influence of PEG on the spherocrystal morphologies of sc-PLA was also investigated using polarized optical microscopy. | CUI Li ZHANG Rundong WANG Yahui ZHANG Chuanjie GUO Yi | 2017 | Wuhan University Journal of Natural Sciences2017，22，5： | 2 |
| 19 | Designing HVDC GIS/GIL spacer to suppress charge accumulation显示文摘To suppress the charge accumulation on the spacer surface in direct current(DC)gas insulated transmission line(GIL)is an important and emergent issue for the development of a clean,safe and economic smart grid.A design method of the DC spacer is proposed,and a spacer prototype is prepared and evaluated both by simulation and type test.The DC withstand voltage test and polarity reversal test are performed using the new DC spacer compared with a commercialised 220 kVAC spacer.The simulation results indicate that the surface electric field and surface charge of the DC spacer are lower than those of the alternating current(AC)spacer under DC voltage.The test results verify that the surface flashover voltage of this DC spacer is higher than that of the AC spacer.The potential feasibility of the spacer design for HVDC is discussed.It is hoped that the content of this paper can bring new ideas in the development of HVDC gas insulated equipment. | Zuodong Liang Chuanjie Lin Fangwei Liang Weijian Zhuang Yujia Xu Lingling Tang Yulin Zeng Jun Hu Bo Zhang Chuanyang Li Jinliang He | 2022 | High Voltage2022，7，4： | 2 |
| 20 | The Correlation between Density and Low-Temperature Creep Property of Asphalt显示文摘The density of asphalt was measured with the pycnometer and densitometer. Creep properties of the asphalt were investigated with the bending beam rheometer at temperatures ranging from 0 ℃ to -36 ℃. The asphalt density data used to correlate with the creep properties were calculated from the regression equation of density and temperature. The asphalt sample used to determine the creep property was aged by the standard RTFOT test and the PAV test. The test results showed that the asphalt density had a linear relationship with temperature changes. The logarithm of the creep stiffness and the slope of the logarithm of the stiffness at 60 seconds all demonstrated a linear relationship with the density, and the regression coefficient of these data was around 0.99. The creep stiffness and the slope of the creep stiffness can be calculated from the asphalt density at the same temperature. | Zhang Xiaoying Xu Chuanjie | 2012 | China Petroleum Processing & Petrochemical Technology2012，14，2： | 2 |
