1China's wetland change (1990-2000) determined by remote sensing显示文摘Two wetland maps for the entire China have been produced based on Landsat data acquired around 1990 and 2000. Wetlands in China have been divided into 3 broad categories with 15 sub-categories except rice fields. In 1990, the total wetland area in China was 355208 km2 whereas in 2000 it dropped to 304849 km2 with a net loss of 50360 km2. During an approximate 10-year period, inland wetland reduced from 318326 to 257922 km2, coastal wetland dropped from 14335 to 12015 km2, while artificial wetland increased from 22546 to 34911 km2. The greatest natural wetland loss occurred in Heilongjiang, Inner Mon- golia, and Jilin with a total loss of over 57000 km2 of wetland. In western China, over 13000 km2 of wetlands were newly formed in Xinjiang, Tibet, and Qinghai. About 12000 km2 of artificial wetlands were also added for fish farm and reservoir constructions. The newly formed wetlands in western China were caused primarily by climate warming over that region whereas the newly created artificial wetlands were caused by economic developments. China’s wetland loss is caused mainly by human activities.Peng Gong ZhenGuo Niu Xiao Cheng KuiYi Zhao DeMin Zhou JianHong Guo Lu Liang XiaoFeng Wang DanDan Li HuaBing Huang et al. 2010Science China Earth Sciences2010,53,7:28
2Progress and records in the study of endogenetic mineralization during collisional orogenesis显示文摘To develop and perfect the theory of plate tectonics and regional metallogeny, metal-logenesis during collisional orogenesis should be thoroughly studied and will attract increasing at-tention of more and more scientists. This paper presents the main aspects of research and discus-sions on metallogenesis during collisional orogenesis after the development of plate tectonics, and accordingly divides the study history into two stages, i.e. the junior stage during 1971-1990 and the senior stage after 1990. Beginning with the negation of mineralization in the collision regime by Guild (1971), the focus of study was put on whether there occurred any mineralization during collisional orogenesis at the junior stage. At the senior stage, which is initiated by the advance of met-allogenic and petrogenic model for collisional orogenesis, scientists begin to pay their attention to the geodynamic mechanism of metallogenesis, spatial and temporal distribution of ore deposits, ore-forming fluidization, relationshipYanjing Chen Huayong Chen Yulin Liu Guangjun Guo Yong Lai Shan Qin Baoling Huang Zengjie Zheng Yinghui Sui Chao Li et al. 2000Chinese Science Bulletin2000,45,1:13
3南方阔叶树材干燥初期应变特点的研究显示文摘在不同温度和平衡含水率条件下研究南方阔叶树材干燥初期应变特点。试验结果表明,干燥初期表层呈现伸张弹性应变和塑性应变,内层为压缩应变,伸张弹性应变的最大值是产生表裂的主要原因,塑性应变而引起的表层固定变形是产生内裂的原因。弹性和塑性应变受平衡含水率的影响较大,并且与含水率梯度存在相关关系、干燥初期阶段的延续时间,可由表层达到最大伸张应变时的含水率与初含水率的比值来确定。Guo Yanming et al.

4中国南方人A型行为问卷测查结果的分析显示文摘本文采用张伯源主持编制的A型行为问卷对中国南方13,808名正常成人进行测查,其中男性7943例,女性5865例。结果表明:我国南方人较北方人行为节凑慢、竞争性强;南方人男性与女性A型行为特征无明显差异,与北方人测查结果一致;不同年龄组的A型行为特征与北方人测查结果相同:即:45~>25~>35~>55~>15~>65岁以上组;不同职业组的A型行为特征是:商业>科技>干部>工人,与北方人测查结果存在一定差异;不同地区(省)间存在较大差异。Guo Huimin et al, Thesurvey cooperative group of the question paper on Chinese Southerners’type A bebavior pattern 1995中国临床心理学杂志1995,3,4:4
5New progress of research on water cycle in atmosphere in China显示文摘New progresses are introduced briefly about the water cycle study on atmosphere of China made in recent years. The introduction includes eight aspects as follows: 1) precipitation characteristics, 2) stability of climatic system, 3) precipitation sensitive region, 4) regional evaporation and evapotranspiration, 5) water surface evaporation, 6) vegetation transpiration, 7) cloud physics, and 8) vapor source.Wang Guo Jia Shao-feng Yu Gui-rui Xu Juan Wang Jin-xia Wang Qiu-feng Ge Quan-sheng Huang Ji-kun Xia Jun Li Li-fnjuan et al. 2001Journal of Geographical Sciences2001,11,4:4
6An L-band HTS duplexer with improved performance显示文摘An L-band HTS duplexer with improved performance for communication applications has been developed.This is an improved version of the duplexer previously developed by our group.The duplexer was composed of a T-junction and two channels.Each channel has a 10-pole quasi-elliptic function bandpass HTS filter with a bandwidth of 27 MHz,and center frequencies at 1200 MHz and 1260 MHz.To achieve higher performance,especially a good balance between selectivity and flat group delay,the two pairs of transmission zeros from the two filters were reassigned so that one pair is used for high selectivity and the other for flat group delay.To reduce the influence of parasitical coupling,new coupling structures were developed in the simulation process.The duplexer was fabricated on a 2 inch diameter,0.5 mm thick LaAlO3 wafer with a double-sided YBCO film.The measured results showed a very high performance:a mid-band insertion loss of 0.2 dB,a return loss better than-14 dB,a shape factor better than 1.4:1,an out-of-band rejection of better than 70 dB in a wide frequency range up to 3 GHz and excellent isolation(higher than 80 dB) between the two channels.In addition,the frequency band 5 ns group delay variation is over 10.5 MHz(38.7% of 1 dB bandwidth).Jia Wang Qiang Zhang Bin Cui Jin Guo YongBo Bian XiaoFeng He ChunGuang Li XueQiang Zhang Hong Li WuXia Li et al. 2010Chinese Science Bulletin2010,55,31:2
