5 the paper also analyze the unique reason for the " senior executives control " phenomenon , and conclude we should establish efficient mechanism from supervisory board , independent director , pluralism of director to assure the controlling power in corporation can be used efficiently to protect the interests of shareholders and state - owned assets 5 、分析了中国企业经营层控制现象的独特原因,从监事会,独立董事和董事长兼任最高经营者等几个方面说明如何建立有效的机制来监督经营层对公司控制权的有效利用以使得股东利益和国有资产得到切实的保护。
One of the content is using efficiently multimedia computer and maths software in teaching process , and potentiating the geometrical teaching by all appearances , translating the difficulty of knowledge , strengthening the understanding of concepts . another content is how to carry out the maths experiments , how to set up the problem for student . it can develop their habits or ability of studying work 研究的主要内容使如何有效地利用多媒体及数学应用软件,加强高等数学的几何直观教学,化解知识的难点,加强概念的理解;开设数学实验,创设探索数学问题的情景,培养学生探索数学问题的习惯和能力。
Abstract : the parallel computer ' s resource can be used efficiently by proper task partitioning and parallel granularity controlling . by analyzing the characteristic of simulation program , this paper points out a task partitioning algorithm which take state equations as core and right - hand function as object . the algorithm has been used in the automatic parallel tools which we have developed and the application results have showed good effect on parallel simulation 文摘:有效地进行任务划分、控制并行粒度,才能充分利用并行计算机的资源,通过对复杂连续系统仿真程序特点的分析,提出了以状态方程为核心、以右函数段的计算为主要对象的自动任务划分算法,使用结果表明具有很好的并行效果。
At the same time , there maybe have some nodes in the cluster with low load and their buffer caches are n ' t used efficiently . on the analysis of linux virtual file system , cache models in cluster file system , mfs and the mechanism of dfsa , the paper import the provesion of cooperate caching to mfs and put forward the mechanism of mosix global cooperate caching ( mgcc ) , which can make all the buffer caches in the cluster cooperate when the cluster is working and make these buffer caches utilize fully , so the overall performance of the mfs can be improved 本文首先分析了mosix中单节点使用的linux虚拟文件系统缓存机制,对机群文件系统中的两类缓存模型:三层缓存体系结构和协作式缓存进行了详细的讨论;在对mosix及其机群文件系统mfs和dfsa机制进行深入研究的基础上,本文把协作缓存机制引入到mfs中,提出了mosix全局协作缓存( mgcc )模型,改进了mosix的缓存策略。
