1Variations between rice cultivars in iron and manganese plaque on roots and the relation with plant cadmium uptake显示文摘To understand certain mechanisms causing variations between rice cultivars with regard to cadmium uptake and tolerance,pot soil experiments were conducted with two rice cultivars of different genotypes under different soil Cd levels.The relationships between plant Cd uptake and iron/manganese(Fe/Mn) plaque formation on roots were investigated.The results showed that rice cultivars di?ered markedly in Cd uptake and tolerance.Under soil Cd treatments,Cd concentrations and accumulations in the cultivar Shanyou 63(the genotype indica) were significantly higher than those in the cultivar Wuyunjing 7(the genotype japonica)(P < 0.01,or P < 0.05),and Shanyou 63 was more sensitive to Cd toxicity than Wuyunjing 7.The differences between the rice cultivars were the largest at relatively low soil Cd level(i.e.,10 mg/kg).Fe concentrations in dithionite-citrate-bicarbonate root extracts of Shanyou 63 were generally lower than that of Wuyunjing 7,and the difference was the most significant under the treatment of 10 mg Cd/kg soil.The results indicated that the formation of iron plaque on rice roots could act as a barrier to soil Cd toxicity,and may be a 'buffer' or a 'reservoir' which could reduce Cd uptake into rice roots.And the plaque may contribute,to some extent,to the genotypic differences of rice cultivars in Cd uptake and tolerance.Jianguo Liu Changxun Cao Minghung Wong Zhijun Zhang Yuhong Chai 2010Journal of Environmental Sciences2010,22,7:43

5Behavior of composite rigid frame bridge under bi-directional seismic excitations显示文摘Pushover analysis and time history analysis are conducted to explore the bi-directional seismic behavior of composite steel-concrete rigid frame bridge,which is composed of RC piers and steel-concrete composite girders.Both longitudinal and transverse directions excitations are investigated using OpenSees.Firstly,the applicability of pushover analysis based on the fundamental mode is discussed.Secondly,an improved pushover analysis method considering the contribution of higher modes is proposed,and the applicability on composite rigid frame bridges under bi-directional earthquake is verified.Based on this method,an approach to predict the displacement responses of composite rigid frame bridge under random bi-directional seismic excitations by revising the elasto-plastic demand curve is also proposed.It is observed that the developed method yield a good estimate on the responses of composite rigid frame bridges under bi-directional seismic excitations.Xiaogang Liu Jiansheng Fan Jianguo Nie Guo Li 2014Journal of Traffic and Transportation Engineering(English Edition)2014,1,1:22
6Identification of long-range transport pathways and potential sources of PM2.5 and PM10 in Beijing from 2014 to 2015显示文摘Trajectory clustering, potential source contribution function(PSCF) and concentration-weighted trajectory(CWT) methods were applied to investigate the transport pathways and identify potential sources of PM_(2.5)and PM_(10) in different seasons from June 2014 to May 2015 in Beijing.The cluster analyses showed that Beijing was affected by trajectories from the south and southeast in summer and autumn. In winter and spring, Beijing was not only affected by the trajectories from the south and southeast, but was also affected by trajectories from the north and northwest. In addition, the analyses of the pressure profile of backward trajectories showed that backward trajectories, which have important influence on Beijing, were mainly distributed above 970 h Pa in summer and autumn and below 950 h Pa in spring and winter. This indicates that PM_(2.5)and PM_(10) were strongly affected by the near surface air masses in summer and autumn and by high altitude air masses in winter and spring. Results of PSCF and CWT analyses showed that the largest potential source areas were identified in spring, followed by winter and autumn,then summer. In addition, potential source regions of PM_(10) were similar to those of PM_(2.5). There were a clear seasonal and spatial variation of the potential source areas of Beijing and the airflow in the horizontal and vertical directions. Therefore, more effective regional emission reduction measures in Beijing's surrounding provinces should be implemented to reduce emissions of regional sources in different seasons.Deping Li Jianguo Liu Jiaoshi Zhang Huaqiao Gui Peng Du Tongzhu Yu Jie Wang Yihuai Lu Wenqing Liu Yin Cheng 2017Journal of Environmental Sciences2017,29,6:22

12A miniature liquid helium temperature JT cryocooler for space application显示文摘Along with the development of space science and technology,miniature liquid helium temperature long life cryocooler is a focus subject in cryogenic study.Since it is the precondition of space detection researches,institutions of space in many countries do the research on it.In this article,we designed a compound cooling system.A three-stage high frequency thermal coupled pulse tube cryocooler was used to precool a Joule-Thomson(JT)cryocooler.This system has no moving parts at low temperatures and is hence suitable for space operation.Liquid helium temperature was successfully achieved in both open loop and closed cycle experiments.In the closed cycle experiment,when 473 W electric power was inputted,the cooling system reached a no-load temperature of 4.4 K,and a cooling capacity of 11.6 mW was provided at 4.54 K.It is the first miniature liquid helium temperature JT cryocooler in China and the research achievement paves a way for the space application of ultra-long wave infrared detection and THz technologies.QUAN Jia ZHOU ZhenJun LIU YanJie LI JianGuo MA YueXue LIANG JingTao 2014Science China(Technological Sciences)2014,57,11:16
13Haze observations by simultaneous lidar and WPS in Beijing before and during APEC, 2014显示文摘We present combined Mie lidar, ozone lidar and wide-range particle spectrometer observations which were carried out in Beijing, north China during two periods—one haze period before the Asia-Pacific Economic Cooperation(APEC) meeting and one moderate pollution period during the meeting in 2014. High extinction coefficient, moderate ozone concentration and variable particle number concentration were obtained throughout the first haze observation period. The mean extinction coefficients in the two pollution periods were 0.52 and 0.23 km?1, respectively, at 532 nm. The ozone concentration during the first haze phase was more various with a higher average value of 49 ppb compared with that in the second pollution observations(32 ppb). Compared with the same metrological condition occurring at the end of October, the sharply decreased aerosol extinction coefficient and ozone concentration show the effectiveness of the emission-cutting measures implemented during APEC in November. The comparison of aerosols and ozone in different heights indicate different pollution sources and the complicated ozone process of generation and disappearance. The correlation between the scattering coefficient and particle number concentrations of various diameter depended on the ambient humidity. Especially the particle number concentration(500 nm–1 ?m) contributed most to PM2.5 concentration. The four-day back trajectories from a Hybrid Single-particle Lagrangian Integrated Trajectory(HYSPLIT) model indicate that the air masses in the lower boundary layer before and during APEC were advected from the densely populated south regions of China and the long pollution transportation passing through northern China.Zhenyi Chen Jiaoshi Zhang Tianshu Zhang Wenqing Liu Jianguo Liu 2015Science China Chemistry2015,58,9:14
14The classification and assessment of freeze-thaw erosion in Tibet显示文摘Freeze-thaw erosion is the third largest soil erosion type after water erosion and wind erosion. Restricted by many factors, few researches on freeze-thaw erosion have so far been done at home and abroad, especially those on the assessment method of freeze-thaw erosion. Based on the comprehensive analysis of impact factors of free-thaw erosion, this paper chooses six indexes, including the annual temperature range, annual precipitation, slope, aspect, vegetation and soil, to build the model for relative classification of freeze-thaw erosion using weighted and additive methods, and realizes the relative classification of the freeze-thaw erosion in Tibet with the support of GIS software. Then a synthetic assessment of freeze-thaw erosion in Tibet has been carried out according to the relative classification result. The result shows that the distribution of freeze-thaw eroded area is very extensive in Tibet, accounting for 55.3% of the total local land area; the spatial differentiation of freeze-thaw erosion with different intensities is obvious; and the difference in distribution among different regions is also obvious.ZHANG Jianguo LIU Shuzhen YANG Siquan 2007Journal of Geographical Sciences2007,17,2:12

16Dynamic mechanical behavior and the constitutive model of concrete subjected to impact loadings显示文摘Based on the theory of consecutive damage mechanics, micro-mechanics, statis-tics and the visco-plastic constitutive equation of Perzyna, a coupled model of damage and plasticity is developed to describe the complex behavior of concrete subjected to impact loadings. In this model, some suppositions about deformation of the material and evolution of the damage are made. First, concrete is macro-scopically assumed to be homogeneous and consecutive, while it is microscopi-cally filled with large amounts of micro-crack and micro-void defects. Second, the damage evolution of the micro-cracks is caused by the nucleation, growth and coalescence of the micro-cracks due to the interior tensile stress in concrete, which leads to a degradation in the strength and stiffness of concrete. Third, compaction of concrete is physically a collapse of the material micro-void. It pro-duces irreversible plastic strains in the material and, at the same time, an increase in the bulk modulus. Fourth, there is no interaction between the micro-crack and the micro-void. Last, when the damage reaches a critical value, the concrete may fail totally. The model parameters for concrete are determined by plate impact ex-periments. The model predictions fit the experimental results well. So the model can be used to simulate the dynamic mechanical behavior of concrete under impact loadings.NING JianGuo LIU HaiFeng SHANG Lin 2008Science China(Physics,Mechanics & Astronomy)2008,51,11:12

18Evaluating Conservation Effectiveness of Nature Reserves Established for Surrogate Species:Case of a Giant Panda Nature Reserve in Qinling Mountains,China显示文摘Many nature reserves are established to protect the habitat needs of particular endangered species of interest but their effectiveness for protecting other species is questionable.In this study,this effectiveness was evaluated in a nature reserve network located in the Qinling Mountains,Shaanxi Province,China.The network of reserves was established mainly for the conservation of the giant panda,a species considered as a surrogate for the conservation of many other endangered species in the region.The habitat suitability of nine protected species,including the giant panda,was modeled by using Maximum Entropy(MAXENT)and their spatial congruence was analyzed.Habitat suitability of these species was also overlapped with nature reserve boundaries and their management zones(i.e.,core,buffer and experimental zones).Results show that in general the habitat of the giant panda constitutes a reasonable surrogate of the habitat of other protected species,and giant panda reserves protect a relatively high proportion of the habitat of other protected species.Therefore,giant panda habitat conservation also allows the conservation of the habitat of other protected species in the region.However,a large area of suitable habitat was excluded from the nature reserve network.In addition,four species exhibited a low proportion of highly suitable habitat inside the core zones of nature reserves.It suggests that a high proportion of suitable habitat of protected species not targeted for conservation is located in the experimental and buffer zones,thus,is being affected by human activities.To increase their conservation effectiveness,nature reserves and their management zones need to be re-examined in order to include suitable habitat of more endangered species.The procedures described in this study can be easily implemented for the conservation of many endangered species not only in China but in many other parts of the world.XU Weihua Andrés VIA QI Zengxiang OUYANG Zhiyun LIU Jianguo LIU Wei WAN Hui 2014Chinese Geographical Science2014,24,1:12
19Haze insights and mitigation in China: An overview显示文摘The present article provides an overview of the chemical and physical features of haze in China, focusing on the relationship between haze and atmospheric fine particles, and the formation mechanism of haze. It also summarizes several of control technologies and strategies to mitigate the occurrence of haze. The development of instruments and the analysis of measurements of ambient particles and precursor concentrations have provided important information about haze formation. Indeed, the use of new instruments has greatly facilitated current haze research in China. Examples of insightful results include the relationship between fine particles and haze, the chemical compositions and sources of particles, the impacts of the aging process on haze formation, and the application of technologies that control the formation of haze. Based on these results, two relevant issues need to be addressed: understanding the relationship between haze and fine particles and understanding how to control PM2.5.Xuliang Zhuang Yuesi Wang Hong He Jianguo Liu Xinming Wang Tingyu Zhu Maofa Ge Ju Zhou Guiqian Tang Jinzhu Ma 2014Journal of Environmental Sciences2014,26,1:12
20Influence of desert sand on the mechanical properties of concrete subjected to impact loading显示文摘A74-mm-diameter Split Hopkinson pressure bar was used to carry out the dynamic compression experiment of concrete made of desert sand.The dynamic failure processes of concrete different in specimen size,impact velocity,desert sand replacement ratio,size and volume content of coarse aggregate were simulated.Research results showed that concrete made of desert sand had size-effect and was rate-dependent.The peak stress of concrete made of desert sand declined with the minimum size of coarse aggregate.However,the peak stress of concrete made of desert sand increased first,and then declined with the volume content and maximum size of coarse aggregate.Liu Haifeng Ma Jurong Wang Yiying Ning Jianguo 2017Acta Mechanica Solida Sinica2017,30,6:12
