| 1 | 东亚地区云的垂直重叠特性及其对云辐射强迫的影响显示文摘本文通过对云观测卫星-CloudSat的2007~2009年3年的观测资料的分析,研究了东亚地区的云的垂直结构.首次计算了在气候模式的云辐射过程中表征云的垂直结构特征的一个重要参数:抗相关厚度L*cf.本文结果表明:6个研究域的抗相关厚度基本处于0~3km的范围之中,根据研究子域的云量不同来划分,抗相关厚度极值出现在云量为0.6~0.8的子域附近,平均约为2.5km.6个研究域的L*cf纬向差异明显,处于较高纬度的北方地区和西北地区的L*cf整体大于较低纬的青藏高原地区和南方地区,而东部海域和东亚地区介于两者之间.不同季节之间的差异表明东亚地区研究域和位于东亚地区西部的西北地区,青藏高原地区和南方地区三个研究域的L*cf具有夏季最大,春、秋次之,冬季最小的特点;位于东亚地区较东部的东部海域和北方地区研究域的L*cf则呈现出冬季最大,春秋次之,夏季最小的特点.其次,利用全球气候模式研究了不同的L*cf值对模拟的云辐射强迫的影响,研究结果表明,不同L*cf取值对模拟的云辐射强迫有很大影响,特别是对全球几个主要的季风区和中东太平洋地区的影响非常大,最高达40~50Wm2左右.因此,在气候模式中精确描述云的垂直重叠结构对提高云辐射强迫模拟精度及其反馈有重要的意义. | 张华 彭杰 荆现文 JiangNan LI | 2013 | 中国科学:地球科学2013，43，4： | 19 |
| 2 | The features of cloud overlapping in Eastern Asia and their effect on cloud radiative forcing显示文摘Characteristics of cloud overlap over Eastern Asia are analyzed using a three-year dataset (2007-2009) from the cloud observing satellite CloudSat. Decorrelation depth Lcf* is retrieved, which represents cloud overlap characteristics in the simulation of cloud-radiation processes in global climate models. Results show that values of Lcf* in six study regions are generally within the range 0-3 km. By categorizing Lcf* according to cloud amount in subregions, peak Lcf* appears near subregions with cloud amount between 0.6 and 0.8. Average Lcf* is 2.5 km. Lcf* at higher altitudes is generally larger than at lower latitudes. Seasonal variations of Lcf* are also clearly demonstrated. The sensitivity of cloud radiative forcing (CRF) to Lcf* in Community Atmosphere Model 3.0 of the National Center for Atmospheric Research (CAM3/NCAR) is analyzed. The result shows that Lcf* can have a big impact on simulation of CRF, especially in major monsoon regions and the Mid-Eastern Pacific, where the difference in CRF can reach 40-50 W m2 . Therefore, accurate parameterization of cloud vertical overlap structure is important to CRF simulation and its feedback to climate. | ZHANG Hua PENG Jie JING XianWen LI JiangNan | 2013 | Science China Earth Sciences2013，56，5： | 13 |
| 3 | Effects of urea plus nitrate pretreated rice straw and corn oil supplementation on fiber digestibility,nitrogen balance,rumen fermentation,microbiota and methane emissions in goats显示文摘Background: Urea pretreatment is an efficient strategy to improve fiber digestibility of low quality roughages for ruminants. Nitrate and oil are usually used to inhibit enteric methane(CH4) emissions from ruminants. The objective of this study was to examine the combined effects of urea plus nitrate pretreated rice straw and corn oil supplementation to the diet on nutrient digestibility, nitrogen(N) balance, CH4 emissions, ruminal fermentation characteristics and microbiota in goats. Nine female goats were used in a triple 3 × 3 Latin Square design(27 d periods). The treatments were: control(untreated rice straw, no added corn oil), rice straw pretreated with urea and nitrate(34 and 4.7 g/kg of rice straw on a dry matter [DM] basis, respectively, UN), and UN diet supplemented with corn oil(15 g/kg soybean and15 g/kg corn were replaced by 30 g/kg corn oil, DM basis, UNCO).Results: Compared with control, UN increased neutral detergent fiber(NDF) digestibility(P < 0.001) and copies of protozoa(P < 0.001) and R. albus(P < 0.05) in the rumen, but decreased N retention(-21.2%, P < 0.001), dissolved hydrogen concentration(-22.8%, P < 0.001), molar proportion of butyrate(-18.2%, P < 0.05),(acetate + butyrate) to propionate ratio(P < 0.05) and enteric CH4 emissions(-10.2%, P < 0.05). In comparison with UN, UNCO increased N retention(+34.9%, P < 0.001) and decreased copies of protozoa(P < 0.001) and methanogens(P < 0.001). Compared with control, UNCO increased NDF digestibility(+8.3%, P < 0.001), reduced ruminal dissolved CH4 concentration(-24.4%, P < 0.001) and enteric CH4 emissions(-12.6%, P < 0.05).Conclusions: A combination of rice straw pretreated with urea plus nitrate and corn oil supplementation of the diet improved fiber digestibility and lowered enteric CH4 emissions without negative effects on N retention. These strategies improved the utilization of rice straw by goats. | Xiumin Zhang Rodolfo F.Medrano Min Wang Karen A.Beauchemin Zhiyuan Ma Rong Wang Jiangnan Wen Lukuyu A.Bernard Zhiliang Tan | 2019 | Journal of Animal Science and Biotechnology2019，10，2： | 10 |
| 4 | Coupling of wave and current numerical model with unstructured quadtree grid for nearshore coastal waters显示文摘This paper presents 2D wave-current interaction model for evaluating nearly horizontal wave-induced currents in the surf-zone and coastal waters.The hydrodynamic model is the two-dimensional depth-averaged nonlinear shallow water equations by using an unstructured non-staggered and multiple-level quadtree rectangular mesh,this mesh information is stored in simple data structures and it is easy to obtain a locally high resolution for important region.The intercell fluxes are computed based on the HLL(Harten-Lax-van Leer) approximate Riemann solver with shock capturing capability for computing the dry-to-wet interface of coastal line.The effects of pressure and gravity are included in source term in the model,this treatment can simplify the computation and eliminate numerical imbalance between source and flux terms.The wave model readily provides the radiation stresses that represent the shortwave-averaged forces in a water column for the hydrodynamic model and the wave model takes into account the effect of wave-induced nearshore currents and water level.The coupling model is applied to verify different experimental cases and real life case of considering the wave-current interaction.The calculated results agree with analytical solution,experimental and field data.The results show that the modeling approach presented herein should be useful in simulating the nearshore processes in complicated natural coastal domains. | ZHANG MingLiang WU WeiMing LIN LiHua YU JiangNan | 2012 | Science China(Technological Sciences)2012，55，2： | 10 |

| 6 | Precipitation behavior and properties of extruded 7136 aluminum alloy under different aging treatments显示文摘In this work, the mechanical properties and electrical conductivity of the extruded 7136 aluminum alloy treated by single-stage aging treatment(T6), retrogression and re-aging treatment(RRA), and multiple retrogression and re-aging treatment have been investigated by means of hardness measurements, electrical conductivity tests and tensile tests. The results have shown that the properties of the 7136 alloy such as hardness, tensile strength and electrical conductivity were sensitive to retrogression time(within 90 min). With prolonging the retrogression time, the tensile strength was enhanced first and then decreased, yet the electrical conductivity was continuously increased. The 60 min-treated alloy performed the highest tensile strength(716 MPa), whereas the 90 min-treated alloy possessed the highest electrical conductivity(33.95%IACS). Compared with the T6-treated alloy, the tensile strength and electrical conductivity were improved by 3.3%and 18.9%, respectively. The electrical conductivity showed an obvious increase with repetitious times of the RRA treatment. After 3 RRA60 treatment, a good combination of tensile strength(705 MPa) and electrical conductivity(33.20%IACS) can be obtained. Compared with the T6 condition, the tensile strength and electrical conductivity were improved by 1.7% and 16.3%, respectively. The mechanism of microstructure evolution under different aging treatments has been discussed in detail. | Huiyan LI Lina JIA Jiangnan HUANG Yue MA | 2021 | Chinese Journal of Aeronautics2021，34，2： | 6 |
| 7 | Directly accessing octave-spanning dissipative Kerr soliton frequency combs in an AlN microresonator显示文摘Self-referenced dissipative Kerr solitons (DKSs) based on optical microresonators offer prominent characteristics allowing for various applications from precision measurement to astronomical spectrometer calibration. To date,direct octave-spanning DKS generation has been achieved only in ultrahigh-Q silicon nitride microresonators under optimized laser tuning speed or bi-directional tuning. Here we propose a simple method to easily access the octave-spanning DKS in an aluminum nitride (AlN) microresonator. In the design,two modes that belong to different families but with the same polarization are nearly degenerate and act as a pump and an auxiliary resonance,respectively. The presence of the auxiliary resonance can balance the thermal dragging effect,crucially simplifying the DKS generation with a single pump and leading to an enhanced soliton access window. We experimentally demonstrate the long-lived DKS operation with a record single-soliton step (10.4 GHz or83 pm) and an octave-spanning bandwidth (1100–2300 nm) through adiabatic pump tuning. Our scheme also allows for direct creation of the DKS state with high probability and without elaborate wavelength or power schemes being required to stabilize the soliton behavior. | HAIZHONG WENG JIA LIU ADNAN ALI AFRIDI JING LI JIANGNAN DAI XIANG MA YI ZHANG QIAOYIN LU JOHN F.DONEGAN WEIHUA GUO | 2021 | Photonics Research2021，9，7： | 6 |
| 8 | Spatiotemporal variations of deep-sea sediment components and their fluxes since the last glaciation in the northern South China Sea显示文摘Sediment components and their fluxes of Cores MD12-3428(water depth: 903 m), MD12-3433(water depth: 2125 m),and MD12-3434(water depth: 2995 m), obtained along a transect on the continental slope of the northern South China Sea, have been conducted to reveal the spatiotemporal variations and the controlling factors of the sediment components and of their fluxes.Results show that deep-sea sediments in the northern South China Sea are composed mainly of terrigenous(59–89%) and carbonate(6–38%) particles, with minor components of opal(1.6–9.4%) and organic matter(0.7–1.9%). Fluxes of terrigenous and carbonate particles reach up to 2.4–21.8 and 0.4–6.5 g cm–2 kyr–1, respectively, values that are one to two orders of magnitude higher than the fluxes of opal and organic matter. Temporal variations of the percentages and fluxes of deep-sea sediment components have displayed clear glacial-interglacial cyclicity since the last glaciation. Terrigenous, opal, and organic matter percentages and their fluxes increas clearly during marine isotope stage 2, while carbonate percentages and fluxes show an opposite variation pattern or are characterized by an unremarkable increase. This implies that deep-sea carbonate in the South China Sea is affected by the dilution of terrigenous inputs during the sea-level lowstand. With increasing water depth along the transect, the terrigenous percentage increases but with largely decreased fluxes. Both the percentage and flux of carbonate decrease, while the percentages and fluxes of opal and organic matter display much more complicated variational features. The spatiotemporal variations of deep-sea sediment components and of their fluxes since the last glaciation in the northern South China Sea are strongly controlled by sea-level fluctuations. Simultaneously, terrigenous supply associated with monsoonal rainfall, marine primary productivity,and the dilution effect between terrigenous and biogenic particles, also play interconnected roles in the sediment accumulation processes. | ZHAO ShaoHua LIU ZhiFei CHEN Quan WANG XingXing SHI JiangNan JIN HaiYan LIU JingJing JIAN ZhiMin | 2017 | Science China Earth Sciences2017，60，7： | 5 |

| 10 | Effects of Ta Addition on NiTi Shape Memory Alloys显示文摘The effect of Ta addition on the martensitic transformation characteristics and the X-ray visibility on NiTi shape memory alloy have been studied in (Ni51Ti49)1-x Tax system. It was found that the transformation temperatures of the Ni51Ti49 binary alloy increased drastically by an addition of 0-4 at. pct Ta, but only slightly when the concentration exceeded 4 at. pct, the addition of Ta greatly decreases the sensitivity of the martensitic transformations to the variation in the Ni-Ti ratio. The addition of Ta to the NiTi binary alloy can improve its X-ray visibility. | Jianlu MA, Jiangnan LIU+, Zhengpin WANG and Fei XUE (Dept. of Materials Science & Engineering, Xi’an Institute of Technology, Xi’an 710032, China) Kuang-Hsi WU and Zhongjie PU (Department of Mechanical Engineering, Florida International University, USA) | 2000 | Journal of Materials Science & Technology2000，16，5： | 3 |

| 12 | A comparison of summer precipitation structures over the South China Sea and the East China Sea based on tropical rainfall measurement mission显示文摘The three-dimensional structures of summer precipitation over the South China Sea(SCS)and the East China Sea(ECS)are investigated based on tropical rainfall measurement mission(TRMM).The primary results are as follows.First,both the convective and stratiform precipitation rates in the SCS are much higher than those of the ECS.The contribution of the convective cloud precipitation to the surface precipitation is primarily over the SCS and the ECS with a proportion of about 70%,but the contribution of convective cloud precipitation is slightly larger in the SCS than the ECS.The contribution of stratus precipitation is slightly larger in the ECS than that in the SCS.Second,the content of cloud particles and precipitation particles in the ECS in June was greater than that in the SCS,while in July and August,the content of cloud and precipitation particles in the ECS was less than that in the SCS.Third,the latent heat profile of the ECS is quite different from that of the SCS.In June,the peak values of evaporation and condensation latent heating rates in the ECS are greater than those in the SCS.In July and August,however,the peak values of evaporation and condensation latent heating rates in the ECS are about 0.05/h less than those in the SCS. | LI Jiangnan YANG Chaofeng LI Fangzhou HE Qihua LI Weibiao | 2013 | Acta Oceanologica Sinica2013，32，11： | 3 |
| 13 | Assessment of soil nematode diversity based on different taxonomic levels and functional groups显示文摘Although soil nematode diversity has been used as an indicator of habitat characteristics and environmental change,the diversity of entire soil nematode communities has not been comprehensively evaluated at different taxonomic levels,or for different functional groups,or at a fine taxonomic level within functional groups.In this study,two taxonomic diversity indices,the Shannon-Wiener index(H′)and Simpson index(l),were used to evaluate the following:1)nematode diversity at different taxonomic levels for the whole community,2)nematode diversity of different functional groups,and 3)nematode generic diversity of functional groups in the following four land-use types:forage land,cropland,secondary forest,and grassshrubland.The results showed that significant differences in nematode diversity among landuse types were detected by assessment at the order level but not at the family or genus level.The results also showed that significant differences in nematode diversity were better revealed by assessment of trophic groups rather than cp groups.The generic diversities(H′)of omnivorous nematodes and cp3 nematodes also significantly differed among land-use types.Our results indicate that diversity at a high taxonomic level(i.e.,order)may be a more useful indicator than diversity at a low taxonomic level(i.e.,family or genus)of differences among land-use types.In addition,the functional group diversity(i.e.,trophic group,cp group,and the combination of these two groups)for the whole community and the taxonomic diversity within functional groups were useful indicators of differences among land-use types. | Jiangnan Li Peiqin Peng Jie Zhao | 2020 | Soil Ecology Letters2020，2，1： | 3 |
| 14 | Separation of mixed salts(Cl-/SO42-) by ED based on monovalent anion selective membranes显示文摘The industrial products or wastewater rich in the mixed salts(Cl-/SO4^2-) not only causes the environmental damage, but also induces waste of resource. In this study, an ED stack with monovalent selective AEMs and conventional CEMs was employed to separate the Cl-and SO42-from simulated wastewater. The effect of current density and mass fraction percentage was investigated in order to optimize the experimental conditions during ED process. It was found that at a concentration ratio between NaCl and Na2SO4 of 95/5(wt%/wt%) and a current density of40 m A·cm^-2, a current efficiency of 72%, an energy consumption of 1.6 k W·h·kg^-1 Na Cl and a Cl-/SO4^2-concentration(67.5/3.5 g·L^-1) were obtained. Hence, it is appropriate and effective to separate Cl-and SO42-by ED using the monovalent selective AEMs. | Jiefeng Pan Wei Zhang Huimin Ruan Jiangnan Shen Congjie Gao | 2019 | Chinese Journal of Chemical Engineering2019，27，4： | 2 |

| 16 | Enhanced production of lutein in heterotrophic Chlorella protothecoides by oxidative stress显示文摘The fast growing unicellular green microalgae Chlorella protothecoides has attracted interest as a promising organism for commercial production of a high-value carotenoid, lutein, by heterotrophic fermentation. Effects of two oxidant-forming reactive oxygen species (ROS) on the biomass concen-tration, and yield and content of lutein in batch culture of heterotrophic Chlorella protothecoides were investigated in this study. The addition of 0.1 mmol/L H2O2 and 0.01 mmol/L NaClO plus 0.5 mmol/L Fe2+ to the culture led to the generation of ·OH and enhanced the lutein content from 1.75 to 1.90 and 1.95 mg/g, respectively. The lutein content further increased to 1.98 mg/g when 0.01 mmol/L H2O2 and 0.5 mmol/L NaClO were added to generate 1O2. The maximum yield of lutein (28.5, 29.8 and 31.4 mg/L) and a high biomass concentration (15.0, 15.3 and 15.9 g/L) were also achieved through the above treatments. The results indicated that 1O2 could promote lutein formation and enhance lutein production in hetero-trophic Chlorella protothecoides. Moreover, 1O2 produced from the reaction of H2O2 and NaClO was more effective in enhancing lutein production and reducing biomass loss than ·OH from the reaction of H2O2 or NaClO plus Fe2+. | WEI Dong1, CHEN Feng2, CHEN Gu1, ZHANG XueWu1, LIU LongJun1 & ZHANG Hao3 1 College of Light Industry and Food Sciences, South China University of Technology, Guangzhou 510640, China 2 School of Biological Sciences, The University of Hong Kong, Hong Kong SAR, China 3 College of Food Sciences, Jiangnan University, Wuxi 214122, China | 2008 | Science China(Life Sciences)2008，51，12： | 2 |

| 18 | Using bipolar membrane electrodialysis to synthesize di-quaternary ammonium hydroxide and optimization design by response surface methodology显示文摘Bipolar membrane electrodialysis(BMED) has already been described for the preparation of quaternary ammonium hydroxide. However, compared to quaternary ammonium hydroxide, di-quaternary ammonium hydroxide has raised great interest due to its high thermal stability and good oriented performance.In order to synthesize N,N-hexamethylenebis(trimethyl ammonium hydroxide)(HM(OH)_2) by EDBM,experiments designed by response surface methodology were carried out on the basis of single-factor experiments. The factors include current density, feed concentration and flow ratio of each compartment(feed compartment: base compartment: acid compartment: buffer compartment). The relationship between current efficiency and the above-mentioned three factors was quantitatively described by a multivariate regression model. According to the results, the feed concentration was the most significant factor and the optimum conditions were as follows: the current efficiency was up to 76.2%(the hydroxide conversion was over 98.6%), with a current density of 13.15 m A·cm^(-2), a feed concentration of 0.27 mol·L^(-1) and a flow ratio of 20 L·h^(-1):26 L·h^(-1):20 L·h^(-1):20 L·h^(-1) for feed compartment, base compartment, acid compartment, and intermediate compartment, respectively. This study demonstrates the optimized parameters of manufacturing HM(OH)_2 by direct splitting its halide for industrial application. | Jiangnan Shen Zhendong Hou Congjie Gao | 2017 | Chinese Journal of Chemical Engineering2017，25，9： | 2 |
