Different climate change in west and east part of north China in recent years is major reason for this phenomenon, not vegetation cover, but degenerated vegetation cover, corresponding to abnormal droughty climate during these period, is one of reasons for abnormally high dust activity in the end of 9Os'in Huabei Plain.

九十年代末，对应于我国北方地区，特别是华北地区干旱少雨的气候条件，植被覆盖状况有明显下降的趋势，这可能是世纪末华北地区沙尘活动频繁的一个重要原因，但我国西部沙尘源区沙尘气溶胶光学厚度仍然保持继续下降的趋势。

There are also several companies in Russia for which tungsten business is not an essential activity. Here is a list of them:"Chelyabinsky electrometallurgical plant" at Ural (Ferro-tungsten and special steels),"Electric steel" in Moscow region (tungsten powder and cemented carbides), JSC "Polema" in Tula (tungsten powder, covering and bars) and JSC "Sandvik-MKTC" in Moscow (hard metal plates and cutting tools).

俄罗斯也有一些公司并不以钨初级产品为主营业务，如位于乌拉尔地区的切利尔宾斯基电冶厂（Chelyabinsky electrometallurgical plant），以钨铁和特种钢为主要产品；位于莫斯科地区的电炉炼钢公司以钨粉和硬质合金为主要产品；位于图拉地区的波勒玛公司，以钨粉、钨涂层及钨条为主要产品；位于莫斯科的山特维克-麦克提克公司（Sandvik-MKTC）以硬质合金板材和切割刀具为主要产品。

SWOT analysis of constructing Three Gorges Area Sport Tourism Circle;2. In order to reveal the evolution process of Three Gorges area,a geomorphy evolution modeling is set up on the basis of DEM by using GIS technology,and a visual method of geomorphy evolution simulation is presented.

为揭示三峡地区地貌演化过程，利用GIS技术，基于DEM，建立起了地貌演化模型，提出了一种可形象直观地进行地貌演化模拟的方法，形象再现了50×104a前三峡地区的地貌形态，并对50×104a以来三峡地区地貌演化进行了过程模拟，结果表明50×104a以来，中部抬升幅度最大。

In accordance of dynamical analysis to asymmetric basin forming, it is restricted doubly by crust multi-layer rheological structure and regional geotectology background in the Lower Yangtze regional crust, especially in close relationship with action of C-layer (18-20km) in the Lower Yangtze region crust. After quantitative analysis of mutual relation between the basin geometrical feature and the crustal structure, a new way will be supplied to the research of Mesozoic-Cenozoic sedimentary basin evolution and the oil -gas exploration in the Lower Yangtze region.

在此基础上，对非对称盆地形成的动力学分析认为，它受下扬子地区地壳多层次流变结构及区域大地构造背景的双重制约，尤其与下扬子地区地壳C层(18-20Km)的活动密切有关，定量分析了盆地的几何学特征与地壳结构之间的相互关系，为下扬子地区中新生代沉积盆地演化的研究及其油气勘探提供了新的研究途径。

The research works on the crust and upper mantle structure in Jiangsu province and its adjacent areas, that is divided into the southeastern Yangzi block, the southern segment of Tancheng-Lujiang fault zone, the eastern segment of Dabie orogen and the Sulu UHPM block according to geotectonics and research level, are introduced based on the results of different research methods such as deep seismic sounding, earthquake travel time tomography and other geophysical survey.

根据江苏及邻区大地构造单元和人工地震研究程度的不同，划分为下扬子地区、郯庐断裂带、大别山东段、苏鲁地块等地区，介绍了利用人工地震、天然地震层析成像及其它地球物理探测等方法对这一地区的深部构造研究结果。

PART ONE Investigation of BDV Natural Infection of Domestic Fowls and Ducks in Chongqing Objective:To investigate the natural infection of Borna Disease Virus of domestic fowls and ducks in Chongqing and explore if the nucleotide sequence in BDV p24 was homophylic with the overseas strains, including standard Strain V and stain He/ 80 , detected from human and animals.

第一部分重庆地区家鸡和家鸭博尔纳病病毒自然感染状况研究目的：为了探讨重庆地区家鸡和家鸭博尔纳病病毒的自然感染状况，分析重庆地区家鸡和家鸭自然感染的BDV p24核苷酸序列与国外人和动物来源BDV分离株及其标准株Strain V和He/ 80的同源性。

The object change will immit some fresh blood in the research field. Because region in a country is an open system, especially for finance, market is highly integrated, and fund and other factor freely flow.

这一研究对象的变化显然会为该领域的研究注入新的血液，因为一个国内的地区相对于其他地区是完全开放的，尤其是对于金融这一要素而言，市场是高度统一的，资金的跨地区流动也没有制度的限制。

From the analysis and discussion of features and significance ofcultivation in the arid winddrift sand areas as well as some currentproblems in the middle part of Ningxia, it can be seen that althoughthe environmental conditions in these areas are poorer for engaging incultivation, cultivation still has an important place in the national eco-nomy, and also plays a decisive role in the stabilization of the liveli-hood of the people, and yet the current problems of cultivation areserious as well.

笔者认为，在我国广大旱作低产区，尤其是农牧交错地区，虽然环境条件有差异，但也都不同程度地存在着类似宁夏中部地区的问题，对于这些问题，期望引起国家有关主管部门的重视，并把这类地区种植业的科学研究纳入我国农业科学研究的轨道。
