Studies on Discriminants for Phylogenetic Extraction of Sheep Populations in East and South of Central Asia;
中亚以东南绵羊群体亲缘血统判别式的研究
Based on the information using the 33 allele frequencies on 10 loci 16 native sheep populations,whose systematic status have been known,the discriminant of extractional status of sheep population in Middle and South-East Asia were detected,the reliability,precision of sampling valuation of the genetic frequencies were analyzed and cognazed.
用系统地位已知的16个地方绵羊群体10个结构基因座位上的33个等位基因频率,验证了中亚以东南绵羊群体血统地位判别式,并对滩羊和小尾寒羊基因频率抽样估计值的可靠性、精确度进行了统计学分析和认定,分别以“一般贴近度”和“遗传贴近度”模糊性判别模式,根据滩羊和小尾寒羊的相应基因频率数据对两者的系统地位作了判别。
Drawing lessons from the thought of data lineage,the concept of file lineage is put forward to describe the security relationship between files.
文章分析了Linux系统文件访问授权及控制机制的不足———孤立地看待文件之间的关联关系,借鉴数据血统思想提出了文件血统的概念,用以描述文件的安全关联。
A File Security Mechanism in Intranet Based on File Lineage and Affinity Degree of Roles;
文件血统与角色亲和度的网络文件安全机制
The access control based on file lineage mechanism is a new ideas and method in recent years,and a file lineage model is presented.
基于文件血统的访问控制机制是近年来提出的一种全新的控制思路与方法,本文是在此基础上,提出了基于血统机制的文件模型。
The paper defines the file lineage,describes the model,and gives a file security mechanism which is achieved through the file lineage s foundation,evolvement,cross and permission operation,based on Linux background.
给出了文件血统的基本定义和模型的描述,并以Linux为背景,给出了一个文件血统的建立、演变、杂交和权限运算的文件安全机制。
