Using the precaution lines of different periods , the end of the paper has analyzed the most possible development trend of yutian oasis - desert transition belt in next 5 or 10 years , and given the constructive advices to local eco - system protection , social or economic project 文章结尾利用所提取的预警线分析了未来5 - 10年内于田绿洲-荒漠过渡带可能的发展趋势,并对当地的生态维护和社会、经济规划提出了建设性意见。
Part sets forth the genetic resources piracy problem . this problem fails to justify the doubts about or objections to the bio - tech inventions patent regime , which prompts the bio - tech advance and influences the distributional structure and mechanism of the accompanied interests . fundamentally , the genetic resources piracy problem is the result of the characteristics of the bio - tech industry . similar to the statutory subject matter as collective creative product though , the genetic resources are not fit for patent system protection because of their ambiguity on subject , object and time 作者承认,我国作为然资源大国,湖资源流失问题严峻,加强贴资源保护研究具有办重要性,但尽管遗传资源作为群体智慧的结晶与专利权所保护的个人发明智力成果辅似之处,却因其找、客体和时问等的不确定性亦4瞄纳入专利权这种私有产哪式的保护之中,最后作者提出了征收雕资源税的初步设想。
This paper makes an introduction to the operating conditions of the western part of handan power network , analyzes the existed problems with economics , reliability , and system protection configuration caused by loop - circuit operation , and points out the necessity of rerouting the western part of handan power network . the two rerouting and transformation schemes are proposed 本文介绍了邯郸西部电网的运行情况,针对该电网的环网运行方式在运行经济性、可靠性、保护配置等方面带来的问题,阐明了邯郸西部电网切改的必要性,对切改方案及其效果进行了研究论证。
Through calculating , analysis , study and comparison , the optimal scheme is recommended and put into practice . the system protection configuring and setting calculation are implemented and the real effectiveness and benefit brought by power rerouting are illustrated . feng hongrun ( electrical engineering and its automation ) directed by prof . gu xueping , a / prof 在对电网结构和运行方式进行深入分析的基础上,提出了两套切改方案,经过计算、分析、研究、论证,得出优选的电网切改方案,并在实际电网得以实施;通过对西部电网进行保护配置及整定计算,验证了电网切改带来的实际效益。

Through lots of experiments of simulation and dynamic simulation , we draw a conclusion that this system owns an excellent foreground . backup protection of system protection is discussed . when main protection does not work , backup protection can cut - off fault within a limit time all the same , which improves electric reliability 详细介绍了系统保护的后备保护,系统保护的后备保护充分借鉴了系统保护的原理,在牺牲部分选择性的同时,仍然可以以较快的速度切除故障,并将故障隔离在最小范围内,进一步增强了供电可靠性。
It integrates the functions of servo amplifier , dynamic operator , position transmitter and remote communication . many new functions have added to its original ones , such as the real - time logical judgment , malfunctions self - diagnosis , alarm & protection , led display , on - line setting and adjustment of functional parameter and position transmitter , power - absence data auto - protection , watchdog system protection , and the long - range communication with pc 系统集伺服放大器、电动操作器、位置发送器及远程网络式通信功能于一体,在保留对应部分原有功能的同时,还新增了逻辑实时判断、故障实时监控、 led动态显示数据、功能参数设置、掉电数据自保护、 “看门狗”电路保护、位置发送器在线调节、与远程工控机数据通信等众多功能。
Unfortunately , in a websphere application server environment , these operating system protections are of limited value because they are based on process identity , which is a very coarse - grained concept when you consider application servers servicing requests from thousands of users at once 遗憾的是,在websphere application server环境中,这些操作系统保护的价值比较有限,因为它们是基于流程识别的,当考虑到应用服务器同时接受数千用户发出的请求时,这是一个非常粗粒度的概念。
