Abstract: 中文摘要:记述了澜沧江云南省西双版纳景洪流域段(22°00.288'N,100°47.430'E)奇额墨头鱼 Garra mirofrontis寄生指环虫属 Dactylogyrus单殖吸虫一新种:澜沧江指环虫 Dactylogyrus lancangjiangensis sp.nov..宿主鱼类的自然感染率为68%(19/28).吸虫平均大小为317 μm×101 μm.后吸器由1对中央大钩、7对边缘小钩、联结片和副联结片组成;联结片呈一字形,中部狭窄,两端较宽;副联结片呈月牙形;交接器包括交接管和支持器,交接管基部膨大呈球形,后部缢缩形成细管,并盘曲成3~5圈螺旋;支持器呈复杂棒状,交接管端部从中穿过.本种在后吸器和雄性交接器上与指环虫属已记录种存在明显差异,同时鉴于单殖吸虫具有较强的宿主特异性,认为该种是科学上一未记录种.模式标本保存于云南师范大学生命科学学院.
英文摘要:A new species of genus Dactylogyrus (Monogenea: Dactylogyridae), Dactylogyrus lancangjiangensis sp.nov., from gills of the host Garra mirofrontis (Cyprinidae) was described in this study. The host was collected from Jinghong city of Lancang River basin, Xishuangbanna of Yunnan Province, 22°00.288' N, 100°47.430' E. Out of the 28 fishes, 19 were infected with the new parasites with prevalence 68%. The mean total body length was about 317 μm, and the mean total body width was 101 μm. The haptor of the new species was consisted of a pair of anchors, 7 pairs of marginal hooks and a connection piece and a accessory connection piece. The connection piece was line-shaped, and became narrow in the middle but wide on both ends; the connection accessory piece was moon-shaped. The copulatory organs were prominent with copulatory tube and hander. The base of copulatory tube was spherically dilated and directly narrowed to form a very thin tube bending 3 to 5 spirals. The hander was clavate and complex, and the end of copulatory tube was throughout the hander. The taxonomic feture of the new species was distinctly distinguished from the recorded Dactylogyrus species, especially the male copulatory organs and haptoral sclerites. In view of the host-specificity and coevolution between Monogenea-fish associations, D. lancangjiangensis sp. nov. was considered as a new species. The specimens were conserved in School of Life Sciences, Yunnan Normal University. 2015,34(3): 403-406 收稿日期:2014-9-3 DOI:10.3969/j.issn.1000-7083.2015.03.014 分类号:Q959.152 基金项目:国家自然科学基金项目(No.30660022,No.30960049,No.31260507);云南省社会发展应用基础研究项目(No.2005C0019Q,No.2009CD049) 作者简介: *通讯作者:范丽仙,E-mail:anne330@163.com 参考文献: 褚新洛, 陈银瑞, 等.1989.云南鱼类志(上册)[M]. 北京: 科学出版社: 269-278. 褚新洛, 崔桂华. 1987. 中国鲤科鱼类墨头鱼属分类的整理[J]. 动物分类学报, 12(1): 93-99. 郎所. 1964. 太湖鱼类寄生蠕虫单殖吸虫Ⅳ. 鲌鱼的寄生指环虫, 包括四新种的描述并论及其系谱分类上的意义[J]. 动物学报, 16(1): 21-23. 马成伦, 李远培. 1991. 四川省鱼类寄生单殖吸虫[J]. 重庆师范学院学报, 8(4): 1-16. 吴宝华, 郎所, 王伟俊. 2000. 中国动物志(扁形动物门: 单殖吸虫纲)[M]. 北京: 科学出版社: 617-622. 吴相云, 谢明权, 李安心. 2007. 指环虫属的早期辐射及其与宿主鲤科鱼类的协同进化关系[J]. 动物学报, 53(4): 651-658. 夏晓勤, 王伟俊, 姚卫建. 2000. 中国内陆水体单殖吸虫的宿主特异性分析[J]. 生态学报, 20(4): 594-597. 肖衡, 叶辉 等. 2012. 动物学野外实习指导[M]. 北京: 高等教育出版社: 141. 赵江山,

Abstract: ?采用真空旋转蒸发和结冰-解冻两种方法浓缩荔枝汁,共得到6种液体。运用顶空固相微萃取和气相色谱-质谱联用法对这6种液体和荔枝原汁的挥发性风味物质进行对比分析。同时将两种浓缩方法进行比较。结果表明:不同浓缩方法得到的荔枝汁挥发性风味物质的种类有所不同,真空旋转蒸发浓缩得到的浓缩荔枝汁挥发性风味物质种类总数少,且有煮熟味,失去了荔枝原汁大部分挥发性风味物质,而其馏出液中含有很多挥发性风味物质,种类和数量较多。而结冰-解冻浓缩法得到浓缩汁的挥发性风味物质种类和数量丰富,无煮熟味,基本保留了荔枝的原有风味,而其剩余液中除乙醇外的挥发性风味物质相对含量很少。

Abstract:
能源是人类赖以生存和发展的物质基础,能源问题与人类生存和发展密切相关,研究城乡居民能源消费行为对提高能源利用率,节约能源资源有重要意义,对统筹城乡发展,建立城乡均等化区域基本公共服务体系有重要影响。本文对长沙市349份城乡居民进行了问卷调查,运用一般多元线性回归模型和Tobit模型对样本能源消费行为及影响因素相关数据进行模型分析。通过分析得出的结论是:长沙市农村居民能源消费是以传统生物质能源和煤为主,而城市居民对电能和天然气的消费量较大;同时,在影响因素中,家庭特征类、家庭财富类和资源可获性等各类因素对居民能源消费行为的影响大小和影响方向因能源种类不同有差异,同种因素对同种能源消费行为也存在城乡差异;最后,为优化城乡能源消费结构,合理开发利用资源,减少非清洁能源的使用,减少废气物排放,减少浪费等提出了相应的政策建议。
Energy is the material foundation for the existence and development of human. Energy problems are closely related to the existence and development of human. The study on energy-consuming behaviors of the rural and urban residents is significant to improve energy efficiency and conserve energy resource, and it is also important to balance urban and rural development and achieve the equalization of basic public service system for urban-rural areas. 349 rural and urban residents in Changsha were investigated with questionnaires. Related data on energy-consuming behaviors and the determine factors were analyzed by using the general multiple linear regression model and Tobit model. The conclusions are: 1) rural residents are primary con-sumers of the biomass energy and coal while urban residents are primary consumers of electrical energy and natural gas in Changsha; 2) Among the influential factors, the effects of family characteristics, family wealth and resource availability on resident energy-consuming behaviors vary according to different types of energy resources; 3) The effects of the same influential factor on the same energy-consuming behavior may be dif-ferent because of the difference between urban and rural areas. Policy suggestions are advanced for optimiz-ing the urban-rural energy consumption structures, rationally developing and utilizing resources, decreasing non-clean energy use, cutting down exhaust emissions and reducing waste.

Abstract: 本文选取重庆和成都统筹城乡以来获得城市户籍的2158名新市民群体为调查对象,揭示农转非新市民城市社会融入的特征,并探究元刻板印象、社会比较、社会距离与满意度对社会融入的影响。结果发现:1) 新市民城市社会融入程度偏低;2) 社会比较以满意度为中介作用于社会融入;3) 积极元刻板印象对社会比较和满意度有显著的调节效果。
From the perspective of psychology, 2158 new citizens from Chongqing and Chengdu participated in the survey. We focused on the extent of adapting to the city for new citizens and explored the influence of the meta-stereotypes, social comparison, warmth and satisfaction on social inclusion. Results showed: 1) The new citizens didn’t adapt into their city in a low extent; 2) Social comparison acted on social integration through the mediating effect of satisfaction; 3) Positive meta-ste- reotype moderates social comparison and social inclusion significantly.
国际投资仲裁裁决在中国的承认与执行

法学家 , 2011,
Abstract: 对ICSID仲裁裁决来说,我国不必就《ICSID公约》在国内的实施特别制定国内法,但建议最高人民法院就法院执行ICSID仲裁裁决的具体问题发布有关司法解释。国内法上的审判监督程序和公共秩序保留制度不能成为我国法院对有关ICSID仲裁裁决的承认与执行进行审查的标准;对其他国际投资仲裁裁决来说,建议对《纽约公约》无法适用于该类裁决在我国的承认与执行的问题予以解决,我国法院也不应以公共秩序保留为由拒绝承认与执行有关国际投资仲裁裁决。国内法院以国家豁免为由拒绝承认与执行有关国际投资仲裁裁决是国际社会所能接受的,我国应争取尽快完成有关国家豁免的国内立法。

Abstract: 建筑环境与人的生理和心理状态息息相关,环境心理学的研究在建筑设计和创作中有着重要的现实 意义。本文通过对不同建筑环境下人类行为反应的观察和分析,进一步研究建筑设计对人心理状态的影响,同时 研究人类的行为和心理对建筑环境的反馈作用,论证了建筑环境对人心理产生巨大的影响,而人的心理又反过来 成为建筑设计中的重要理论依据。
The architecture environment is closely related to human physiological and psychological state. The study of environmental psychology is of practical significance in architectural design and creation. The author observed and analyzed human behavior responses in different architectural environments, and then further studied the influence of architectural design on people’s mental state and the feedback effect of human behavior and psychology on the architectural environment. This demonstrates that the architectural environment has a great impact on human psychology, and meanwhile, human psychology in turn has become an important theoretical basis for architectural design

Abstract: 通过盆栽试验收集了不同生育期单作和间作小麦、蚕豆的根系分泌物,用hplc分析了根系分泌物中低分子量有机酸的含量和种类.结果表明:小麦-蚕豆间作显著提高了有机酸的分泌量,在小麦分蘖期(57d)、孕穗期(120d)和灌浆期(142d),间作使小麦根系有机酸分泌量分别提高155%、35.6%和92.6%;在蚕豆分枝期(57d)和籽粒膨大期(142d),间作使蚕豆根系有机酸分泌量提高87.4%和38.7%.小麦-蚕豆间作改变了根系分泌物中有机酸的种类,与单作小麦相比,在分蘖期,间作小麦根系分泌物中增加了乳酸;在拔节期(98d),间作小麦根系分泌物中增加了柠檬酸,但未检测到乙酸;在蚕豆分枝期,间作蚕豆根系分泌物中增加了乙酸,但未检测到乳酸;在蚕豆籽粒膨大期,间作蚕豆根系分泌物中增加了乳酸.小麦-蚕豆间作提高了小麦根系有机酸的分泌速率,在小麦孕穗期,间作小麦分泌柠檬酸、富马酸的速率是单作小麦的179和184倍;在小麦灌浆期,间作小麦分泌乳酸的速率是单作的2.53倍.总之,小麦-蚕豆间作增加了有机酸的分泌量,改变了根系分泌物中有机酸的种类,提高了小麦根系有机酸的分泌速率.

应用生态学报 , 2004,
Abstract: 基于地理信息系统软件arcgis,数字化祁连山西水自然保护站1:100000地形图,生成研究区高程图和坡向图,并同植被图叠加,分析各景观组分在空间的分布特征,用定量分析景观结构程序fragstats分析景观结构特征.结果表明,研究区各景观组分空间分布极不均衡,受海拔和坡向的影响非常明显.草地是面积最大、连结性和完整性最好的景观组分;青海云杉林斑块形状最为不规则,平均斑块面积小而距离近,最易因受到干扰而发生重大变化;宜林地和祁连圆柏林相对于农田、疏林地有较强的扩张特征.杨桦阔叶林各斑块相隔距离大而分散,斑块之间的邻接性很差,破碎化最为严重.
