| 1 | Sensitivity analysis of project level MOVES running emission rates for light and heavy duty vehicles显示文摘In order to understand how the uncertainties in the output can be apportioned to different sources of uncertainties in its inputs,it is critical to investigate the sensitivity of MOVES model.The MOVES model sensitivity for regional level has been well studied.However,the uncertainty analysis for project level running emissions has not been well understood.In this research,the MOVES model project level sensitivity tests on running emissions were conducted thru the analysis of vehicle specific power(VSP),scaled tractive power(STP),and MOVES emission rates versus speed curves.This study tested the speed,acceleration,and grade-three most critical variables for vehicle specific power for light duty vehicles and scaled tractive power for heavy duty vehicles.For the testing of STP,four regulatory classes of heavy duty vehicles including light heavy duty(LHD),medium heavy duty(MHD),heavy heavy duty(HHD)and bus were selected.MOVES project running emission rates were also tested for CO,PM2.5,NOx,and VOC versus the operating speeds.A Latin Hypercube(LH)sampling based on method for estimation of the'Sobal'sensitivity indices shows that the speed is the most critical variable among the three inputs for both VSP and STP.Acceleration and grades show lower response to the main effects and sensitivity indices.MOVES emission rates versus speeds curves for light duty vehicles show that highest emission occurs at lower speed range.No significant differences on emission rates among the regulatory classes of heavy duty vehicles are identified. | Zhuo Yao Heng Wei Harikishan Peragu Hao Liu Zhixia Li | 2014 | Journal of Traffic and Transportation Engineering(English Edition)2014，1，2： | 8 |

| 3 | Preventative effect of massage on gastric volvulus in infants with gastroesophageal reflux-induced pneumonia显示文摘OBJECTIVE:To study the preventative effects of massage on gastric volvulus(GV) in infants with gastroesophageal reflux(GER)-induced pneumonia.METHODS:One-hundred and eighty GV with GER-induced pneumonia inpatients were divided randomly into four groups:basic treatment 1(n =60),basic treatment 2(n = 30),massage treatment1(n = 60) and massage treatment 2(n = 30).Clinical examinations selected between groups 1 and 2were different.Radiography of the upper gastrointestinal tract using iodine-containing contrast was assessed in group 1 before and after treatment,whereas 24-h pH monitoring of the distal esophagus was assessed in group 2 before and after treatment.Symptom scores and chest radiography were assessed in all groups upon hospital admission and after procedures.Clinical effects were estimated after procedures in all groups.The prevalence of severe pneumonia among the four groups was compared.RESULTS:Massage treatment groups showed a significantly higher percentage of cure and total effect(P<0.05,P<0.01) and a lower prevalence of recurrence(but with no statistic difference,P>0.05)than basic treatment groups.Furthermore,massage treatment groups had remarkably lower scores for symptoms and signs(P<0.05,P<0.01),especially for choking on milk,than basic treatment groups.There was significant attenuation of chest inflammation(P<0.05,P<0.01),GV(P<0.05,P<0.01) and GER(P<0.05,P<0.01) in massage treatment groups compared with those in basic treatment groups.Finally,massage treatment groups demonstrated a lower prevalence of severe pneumonia than basic treatment groups(P<0.05).CONCLUSION:Massage treatment can prevent GV with GER-induced pneumonia in infants by timely correction of stomach rotation and subsequent attenuation of GER. | Yan Suqi Xiong Xiaoli Wan Qi Liu Fan Tang Jianqiao Jiang Zhixia Zhou Lishan Yuan Kai Xie Dong | 2015 | Journal of Traditional Chinese Medicine2015，35，5： | 3 |
| 4 | Comprehensive Assessment of Urbanization Coordination:A Case Study of Jiangxi Province, China显示文摘In order to make assessment on urbanization coordination, we developed a comprehensive model by integrating entropy weight method(EWM), coupling degree model(CDM), coupling coordination degree model(CCDM), multi-index grading method(MIGM) and Remote Sensing & Geographic Information System(RS & GIS) technology. Then we applied this integrated model to a case study in Jiangxi Province, China. Our study finds that: 1) EWM, CDM and CCDM can evaluate the temporal dynamic of urbanization. Urbanization process of Jiangxi Province can be divided into three periods, the stable development period(1990–2001), the accelerated development period(2002–2009) and the rapid development period(2010–2015). Coordinated development of urbanization in Jiangxi Province can be divided into two phases, an increasingly coordinated phase(1990–2003) and an increasingly incongruous phase(2003–2015). The state transition was due to low development rate of population urbanization. 2) RS & GIS technology is an effective tool for detecting urban growth. Urban construction land area of Jiangxi Province increased from 615.8 km^2 in 1990 to 2896.8 km^2 in2015, and the per capita urban construction land area(PCUCLA) reached 122.9 m^2, with the maximum value of 343 m^2 in Gongqingcheng City. 3) MIGM and RS & GIS technology can analyze spatial difference of urbanization. There is a significant spatial difference in socioeconomic development at county scale, with the maximum value six times the minimum value for both PCUCLA and per capita GDP in 2015. Population urbanization lag and excessive land use are the main reasons for uncoordinated urbanization. There were 15 counties with a lag in demographic urbanization and 33 counties where PCUCLA exceeded the national standard in 2015, among which 20 exceeded the national standard of PCUCLA by 50%(≥165 m^2). Since there are significant spatio-temporal differences in urbanization, it is necessary to carry out a comprehensive assessment to facilitate differential urbanization strategy making. | LI Shu YING Zhixia ZHANG Huan GE Gang LIU Qijing | 2019 | Chinese Geographical Science2019，29，3： | 3 |
| 5 | Grain Yield, Quality and 2-Acetyl-1-Pyrroline of Fragrant Rice in Response to Different Planting Seasons in South China显示文摘Climate conditions is an important factor affected the fragrant rice growth and development.In order to study the effects of different planting seasons on fragrant rice performance in South China,present study was conducted with three planting seasons(early season(April to July),middle season(June to September)and late season(August to November))and three fragrant rice cultivars,‘Basmati-385’,‘Meixiangzhan-2’and‘Xiangyaxiangzhan’.The results showed that the highest grain yield and grain 2-acetyl-1-pyrroline(2-AP,key component of fragrant rice aroma)content were both recorded in late season treatment while the fragrant rice in middle season treatment produced the lowest grain yield,grain filling percentage,1000-grain weight and gain 2-AP content.The highest contents of precursors(proline,pyrroline-5-carboxylic acid and 1-pyrro-line)which related to 2-AP biosynthesis were recorded in late season treatment compared with early season treatment and middle season treatment.The highest activities of enzymes(proline dehydrogenase,pyrroline-5-carboxylic acid synthetase and ornithine transaminase)which involved in 2-AP biosynthesis were also observed in late season treatment.Moreover,the fragrant rice cultivars in late season possessed the lowest chalk rice rate,chalkiness as well as the highest brown rice rate,head rice and protein content.Thus,the optimal season for fragrant rice production in South China is the late season. | Leilei Kong Haowen Luo Zhaowen Mo Shenggang Pan Zhixia Liu Qiang Zhang Song Bai Xiangru Tang | 2020 | Phyton-International Journal of Experimental Botany2020，89，3： | 2 |

| 9 | A new type-γ'/γ''coprecipitation behavior and its evolution mechanism in wrought Ni-based ATI 718Plus superalloy显示文摘In the precipitation-hardened Ni-based superalloy,typified by ATI 718 Plus,the nano-scaleγandγphase in duplet or triple coprecipitate morphology can provide superior high-temperature strength.Thus,it is of great sense to study the evolution ofγ’/γ’’coprecipitate during long term service at elevated temperature.In this study,the new-typeγ’/γ’’coprecipitates with a sandwich or compact configuration were found firstly in wrought ATI 718 Plus superalloy during long term thermal exposure at 705℃.These co-structure of theγ’/γ’’precipitates evidently inhibit the coarsening ofγ’phase.The increase of thermal exposure time evidently leads to the increase of the volume fraction ofγ’/γ’’coprecipitate and transformation of sandwich-typeγ’/γ’’coprecipitate to compact-typeγ’/γ’’coprecipitate,which is characterized asγphase precipitate at several faces of theγphase.The main evolution mechanism ofγ’/γ’’coprecipitates is element segregation,especially the composition variations of Al+Ti and Nb and their ratio of Al+Ti/Nb.In addition,the interfacial energy betweenγ’’phase andγmatrix also plays a key role on theγ’/γ’’coprecipitates evolution.The calculated results show that the longer thermal exposure time leads to the higher interfacial energy,which is beneficial for nucleation and precipitation ofγ’’phase on the faces ofγ’phase. | Qianying Guo Zongqing Ma Zhixia Qiao Chong Li Teng Zhang Jun Li Chenxi Liu Yongchang Liu | 2022 | Journal of Materials Science & Technology2022，，24： | 1 |

| 18 | Deep Convective Clouds over the Northern Pacific and Their Relationship with Oceanic Cyclones显示文摘Based on combined Cloud Sat/CALIPSO detections, the seasonal occurrence of deep convective clouds(DCCs) over the midlatitude North Pacific(NP) and cyclonic activity in winter were compared. In winter, DCCs are more frequent over the central NP, from approximately 30°N to 45°N, than over other regions. The high frequencies are roughly equal to those occurring in this region in summer. Most of these DCCs have cloud tops above a 12 km altitude, and the highest top is approximately 15 km. These wintertime marine DCCs commonly occur during surface circulation conditions of low pressure, high temperature, strong meridional wind, and high relative humidity. Further, the maximum probability of DCCs,according to the high correlation coefficient, was found in the region 10°–20° east and 5°–10° south of the center of the cyclones. The potential relationship between DCCs and cyclones regarding their relative locations and circulation conditions was also identified by a case study. Deep clouds were generated in the warm conveyor belt by strong updrafts from baroclinic flows. The updrafts intensified when latent heat was released during the adjustment of the cyclone circulation current. This indicates that the dynamics of cyclones are the primary energy source for DCCs over the NP in winter. | YI Mingjian FU Yunfei LIU Peng ZHENG Zhixia | 2015 | Advances in Atmospheric Sciences2015，32，6： | 1 |
| 19 | Effects of Heat Clearing and Stasis Resolving Method on PTS,Inflammatory Factors and T-lymphocyte Subsets in Peripheral Blood of URM Patients with Suppressed Internal Heat显示文摘[Objectives]To explore the effects of heat clearing and stasis resolving method on prethrombotic state,inflammatory factors and T-lymphocyte subsets in peripheral blood of unexplained recurrent miscarriage(URM)patients with suppressed internal heat.[Methods]Thirty cases of URM patients with suppressed internal heat and 30 normal women were collected,and characteristics of changes in peripheral serum D-dimer(D-D),fibrin degradation product(FDP),fibrinogen(FIB),IL-6,IL-10 and TNF-α,CD,CD,CD,CD,CDlevels were detected.URM patients were treated with traditional Chinese medicine for clearing heat and resolving blood stasis for 3 menstrual cycles,and the changes of indicators before and after treatment were observed.[Results]Compared with normal women,the peripheral serum levels of D-D,IL-6,TNF-αand CDin URM patients with suppressed internal heat were increased(P<0.05),while the IL-10 lymphocyte level was significantly decreased(P<0.05);compared with that before treatment,the contents of D-D,IL-6,TNF-αand CDdecreased after 3 menstrual cycles(P<0.05),while the contents of IL-10 and CDT lymphocytes increased significantly(P<0.05).[Conclusions]The heat clearing heat and stasis resolving method can effectively improve the prethrombotic state of URM,and the action mechanism may be related to the regulation of immune and peripheral blood inflammatory factors. | Fenqin ZHAO Jieying LIU Yan ZHAO Yajiao GOU Zhixia HU | 2022 | Medicinal Plant2022，13，4： | 0 |
| 20 | Effects of Macronutrients on Primary and Secondary Metabolism in Scutellaria baicalensis Georgi显示文摘[Objectives] This study was conducted to clarify the roles of macronutrients in regulating plant primary and secondary metabolism of Scutellaria baicalensis Georgi. [Methods] The contents of chlorophyll(Chl) and soluble sugar were detected with ultraviolet spectrophotometry. The activities of phenylalanine ammonia-lyase(PAL), cinnamate 4-hydroxylase(C_4H) and chalcone synthase(CHS) were determined with ultraviolet spectrophotometry. Secondary metabolites were detected by high performance liquid chromatography(HPLC). [Results] The content of chlorophyll in treatments N, P and K was increased, showing significant difference from that of the control(P<0.05). Among them, Treatment N has the highest content of chlorophyll. Soluble sugar content in treatments N, P and K(K>N>P>CK) was increased considerably and had significant difference from that of the control(P<0.05). Compared with the control, PAL and C_4H activity in treatments N, P and K were increased dramatically by 186.57%, 134.09%, 306.91% and 73.21%, 28.91%, 247.57%, respectively. CHS activity was also increased sharply in treatments N, P and K. Scutellarin, baicalin, wogonoside, baicalein, wogonin and oroxylin A contents in all treatments N, P and K(K>N>P) were increased, and had significant difference from that of the control(P<0.05). [Conclusions] The results showed that macronutrients can increase leaf chlorophyll content, soluble sugar content, PAL activity, C_4H activity and secondary metabolites of S. baicalensis. | Jinhua LIU Yanjing BIAN Zhixia LI Yongqing ZHANG | 2019 | Agricultural Biotechnology2019，8，2： | 0 |
