Under the environment of LAN, NAS can totally realize the data grade sharing between different platforms. 在LAN环境下,NAS已经完全可以实现异构平台之间的数据级共享。
The control over administrators was enhanced on the server system level. The data security grade was divided, and the data was encrypted on data level. Authority distribution and control of visitors were enhanced via role-based access control on application level. 在服务器系统层面加强对管理员的控制;在数据层面划分数据安全等级和对数据进行加密处理;在应用程序层面通过基于角色的访问控制加强对访问用户的权限分配和控制。
Measurement data between groups and within groups were analyzed using ANOVA and paired t test, chi-square test with count data, grade data using Kruskal-wallis test analysis. 计量资料组间及组内分别用单因素方差分析及配对t检验,计数资料采用卡方检验,等级资料采用Kruskal-wallis检验分析。
This paper puts forward a genetic algorithm method to find automatically optimum powers of distance power inverse ratio method based on the actual data of grade control points. 应用遗传算法提出了自动确定距离幂次反比法品位估计公式中最优幂次的方法。
A Genetic programming method to find the true formula of grade estimation scientifically was put forward based on the actual data of grade control points. 以品位实测数据为基础,提出了科学发现矿体真实品位估计公式的遗传规划方法。
