Reliability Estimations of Control Systems Effected by Several Interference Sources

In order to establish the sufficient and necessary condition that arbitrarily reliable systems can not be constructed with function elements under interference sources, it is very important to expand set of interference sources with the above property. In this paper, the models of two types of interference sources are raised respectively: interference source possessing real input vectors and constant reliable interference source. We study the reliability of the systems effected by the interference sources, and the lower bound of the reliability is presented. The results show that it is impossible that arbitrarily reliable systems can not be constructed with the elements effected by above interference sources.     

The range of life in amber: significance and implications in DNA studies

A survey of the major fossiliferous amber deposits is provided, including ages and various categories of life forms reported from each. The frequence of occurrence of the major groups of plants and animals in these amber deposits is also given. Thus far, DNA from four insect and one plant species has been extracted from amber fossils. In the case of the stingless bee in Dominican amber, evidence of reproducibility is provided, since two independent laboratories isolated DNA from six or more different specimens of the same insect.Amber sources for DNA studies are listed together with their advantages and disadvantages. The important points are the availability of desired pieces, the proper identification of the fossil, verification of the amber deposit, the cost involved, and the feasibility of causing damage to the specimen. The availability of several types of amber (Mexican, Dominican, Baltic, Chinese, Canadian, Siberian and Lebanese) at four major sources (academic collections, commercial dealers, private collections and amber mines) is discussed. The scientific implications of obtaining DNA from amber inclusions are presented.

污染源对大气环境质量影响模拟(Ⅰ)

本文介绍SXVEQAS(山西大学环境质量评价系统)中污染源对大气环境质量影响模拟的数学方法。全文分为两大部分,第一部分为单污染源影响模拟方法,主要介绍长期平均浓度等浓度曲线与污染区划分的计算方法,并以岳南矿为实例说明。下文将介绍第二部分,介绍多污染源影响模拟的一些数学方法。它主要研究使用网格法进行对大气污染形势模拟、大气污染预报、等浓度曲线和污染区域划分计算的数学方法,这是区域性环境质量评价与环境规划中急待解决的关键问题。     

试论中国古代固有民法的开放性体系

近年来法律史研究中对正律以外的大量史料的考证足以说明:既然中国古代曾有辉煌的国际和国内贸易是不争的事实,且调整这些社会关系的大量的行为规则和裁判规则的存在亦不容置疑,那么,只要转换思路,从实质意义上的民法渊源的角度来看问题,就不但可以发现中国古代固有民法的实在体系,而且能够概括出其特有的调整模式。这无疑对目前我国民法典的编纂同样具有重要的现实意义。     

景德镇市生态旅游开发的初步构想

景德镇市生态旅游资源丰富,其优势区域在浮梁县,瑶里尤为突出,拥有瓷之源,茶之乡,林之海的美誉。另外,浮梁县水上生态旅游资源也值得大力开发。     

DENISON经济增长因素分析的模型化与经济增长方式

丹尼森的经济增长因素分析是对经济增长理论的重要贡献, 但他没有提供模型化方法。本文提出了对丹尼森的经济增长因素分析进行定量化模型化的方法, 并利用这种模型化方法讨论了经济增长来源与经济增长方式的问题。
