It expanded to 106119ha in 1973, descented to 99167ha in 1987, backed up to 112440ha, and attained the max value in history—123170ha in 1998 and descent to 109934ha again in 2001. GIS overlaying analysis shows that, the spatial change of Minqin Oasis had the different characteristics in different stage in the last 50 years: at the end of 50's to the beginning of 70%, oasis expandation Was performed by extension of origin oasis; the atrophia of oasis from the beginning from 70's to the 80's was performed by increasing of non-oasis spot pieces of inner part for oasis; the main performance of keeping on expanding of oasis from late 80's to late 90's is outside extension of Baqu oasis near the upper stream, with increased oasis area in interior of hungriness and increased area of non-cultivation in Huqu oasis in the north. From 1998 to 2001, opening up wideness in interior of hungriness continued, but hnngrinessization of oasis became worse. The oases in the Minqin Basin developed from small to large and back to small in terms of area changes, and from south to north then to south in terms of spatial changes.

绿洲分布图的GIS叠加覆盖分析表明，近50年来民勤绿洲的空间变化在不同阶段有不同的特征：50年代末至70年代初，绿洲扩展主要表现为已有绿洲的外延式扩大；70年代初至80年代后期的绿洲萎缩，主要表现为绿洲内部非绿洲斑块增加；80年代后期至90年代后期的持续扩展，主要表现为靠近上游的坝区绿洲向外围扩展和荒漠腹地绿洲面积的增加，而北部湖区绿洲弃耕面积不断扩大；98年至2001年，绿洲荒漠腹地的开荒还在继续，但湖区的绿洲荒漠化还在进一步加剧。50年来民勤绿洲的发展总体上经历了一个面积由小到大再到小，空间位置上从南而北再向南的迁移过程。

ABSTRACT The aim of the project is to prepare the high temperature superconducting thin films which can satisfy the need of future applications in the field of power transmission. By using biaxially textured Ni (001) and Ag (110) as substrates, the YBCO films with high critical current were obtained under the optimized deposition conditions. Some results were obtained as follows: We developed a simple approach to prepare YBCO films doped with Ag nanograins.

本工作的研究目的是在金属基带上制备出能够满足未来超导强电应用的超导薄膜小样品，其具体的做法是在双轴织构的Ni（001）和Ag（110）基带上外延YBCO高温超导薄膜，经过不断地优化工艺条件，我们得到如下结果：发展了一种在YBCO薄膜中掺入Ag颗粒的方法，这种方法具有可以随时改变掺杂量的特点。

Altogether there are seven chapters in this article. Chapter one starts with the historical background caused by the occurrence of the concept of sexual harassing and analyzes the reasons of sexual discrimination which is brought forward by Catharine A Mackinnon when defining the concept of sexual discrimination. Meanwhile, she analyzes the employers' responsibilitiy which appears to be another feature , has a brief presentation on the gradually widened connotation and denotation extension of the American law and a step- by- step-built anti-sexual harassing law system that is learned from by most of the countries. This chapter helps us to have a general understanding of the overseas anti-sexual harassing law system represented by America. Chapter two is about the analysis of the phenomenon of the Chinese sexual harassing. Before the first sexual harassing case appeared in 2001, it doesn't belong to the concept of law.

第一章从性骚扰概念产生的历史背景入手，分析了麦金侬提出性骚扰概念时将性骚扰定性为性别歧视的原因，对性骚扰概念另一特色雇主责任进行了分析，并简述了美国法律通过不断扩大性骚扰概念的内涵和外延，逐步建立起一套符合本国国情并为世界大多数国家所仿效的反性骚扰法律体系，该章使我们对以美国为代表的国外反性骚扰法律体系有一个全面的了解。
