The Qinling Mountains are the main source of water supply to the Weihe River and Hanjiang River,but systematic studies on runoff changes in this region are *** study simulated the annual runoff in the Qinling Mountains from 1970 to 2015 using the Variable Infiltration Capacity(VIC)hydrological model and projected runoff changes from 2015 to 2100 under different Shared Socio-economic Pathways(SSPs).Moreover,the water demand in the north and south of the Qinling Mountains from 2019 to 2100 was analyzed by constructing a system dynamic *** results show that the mean annual runoff in the southern and northern slopes of the Qinling Mountains from 1970 to 2015 were 21.5×10^(9) and 3.52×10^(9) m^(3),*** the SSP1-2.6,SSP2-4.5,SSP3-7.0,and SSP5-8.5 scenarios from 2015 to 2100,the mean annual runoff in the southern(northern)slope will increase by 2.9(1.5),2.0(1.4),2.7(1.6),and-2.1(0.4)×10^(9) m^(3),*** mean annual water consumption in the northern foothills of the Qinling Mountains for Baoji,Xi’an,and Weinan cities is projected to increase from 4.1×10^(9) m^(3) in 2015 to 7.6×10^(9) m^(3) in 2100,while that in the southern foothills for Hanzhong,Ankang,and Shangluo cites is projected to increase from 2.7×10^(9) m^(3) in 2015 to 4.8×10^(9) m^(3) in ***,runoff in the southern slope is much larger than the water demand in the southern *** increase of runoff in the northern slope cannot satisfy the water demand in the northern ***,the South-to-North Water Transfer project is proposed for meeting the water demand in the northern *** the premise of ensuring downstream water demand,approximately 10.5×10^(9) m^(3) of water resources can be transferred from the southern slope to the Weihe River and the Beijing-Tianjin-Hebei-Henan regions under SSP1-2.6,but only 3.9×10^(9) m^(3) can be transferred under SSP5-8.5.

The plant mitochondrial genome displays complex features, particularly in terms of cytoplasmic male sterility （CMS）. Therefore, research on the cotton mitochondrial genome may provide important information for analyzing genome evolution and exploring the molecular mechanism of CMS. In this paper, we present a preliminary study on the mitochondrial genome of sea island cotton （Gossypium barbadense） based on positive clones from the bacterial artificial chromosome （BAC） library. Thirty-five primers designed with the conserved sequences of functional genes and exons of mitochondria were used to screen positive clones in the genome library of the sea island cotton variety called Pima 90-53. Ten BAC clones were obtained and verified for further study. A contig was obtained based on six overlapping clones and subsequently laid out primarily on the mitochondrial genome. One BAC clone, clone 6 harbored with the inserter of approximate 115 kb mtDNA sequence, in which more than 10 primers fragments could be amplified, was sequenced and assembled using the Solexa strategy. Fifteen mitochondrial functional genes were revealed in clone 6 by gene annotation. The characteristics of the syntenic gene/exon of the sequences and RNA editing were preliminarily predicted.

Sexual violence, a prevalent problem in the spousal relationship, is closely related to the issue of female consciousness. In The Babysitter, Coover （1989） tells of a teenage girl babysitting two kids and a baby and of two of her male peers and the children＇s father altogether exploring their obsession towards her and, moreover, traces the evaluation and devaluation of women to the presentation of TV exploring its influence on his heroines, namely Mrs. Tucker and the babysitter serving as victims of the patriarchal society. Through a close engagement with the sexual objectification theory, this paper analyzes in detail men＇s aggressive oppressions upon women as well as women＇s compromise and rebellion towards the sexual violence, and investigates that the awakening of female independent consciousness is a key factor in effectively helping women achieve the gender equality between sexes.

传统意义混合像元分析方法是对有不同光谱特征的地物进行分解(spectral mixture analysis,SMA),得到各个组分在该像元内所占的百分数。而将光谱域的混合像元分析延伸至时间域内(temporalmixture analysis,TMA),提取的表征时间特性的端元用于像元分解所得残差小于8.5%,说明TMA提取南极地区海冰密集度时间变化特性具有可行性。将获取的多年平均端元用于2005年和2010年海冰密集度数据,得到残差分别为(1.4±2.42)%和(1.7±2.87)%,高于多年平均残差精度(1±1.53)%,在一定程度上反映某年海冰密集度数据相对多年平均值的变化。因此,TMA为全球变暖背景下的海冰密集度的时空特性研究提供了新思路。

根据《中国入世议定书》第15条(a)款(ii)规定,在对中国进行反倾销调查确定可比价格时,中国被视为非市场经济国家,以第三国价格作为确定倾销的正常价值。同时第15条也做出规定,该歧视性条款将在中国入世15年后废除。一种观点认为这一规定意味着中国将在2016年底自动获得市场经济地位认可。然而近年来围绕中国在2016年底自动获得市场经济地位的问题,国内外又掀起了争论。本文在考察中国入世条款中"非市场经济地位"问题由来的基础上,梳理近年来的主要争论,并分析"非市场经济地位"歧视性反倾销条款对中国经贸的影响,最后针对部分国家拒不承认中国市场经济地位提出中国可采取的应对措施。
