After quantitative analyses and theoretical exploration , some important results and conclusions are as below : ( 1 ) ed not regarded , both ka and id are significantly positive to fp ( both significant levels are lower than 0 . 01 ) , but ii and om do not significantly contribute to fp . the moderation effects of ed on the relationships between ol and fp truly exist : the higher the technological or market dynamics , the more the marginal contribution of ka , id , and om to fp ( significant levels are all lower than 0 . 01 ) 通过定量实证研究和理论探讨，本文主要得到如下的一些结果或结论： ( 1 )不考虑环境动态性因素，知识获取和信息分发对于企业绩效的提升具有积极显著的作用( p值均小于0 . 01 ) ，但是信息解释和组织记忆对企业绩效则没有产生显著影响；环境动态性对组织学习与企业绩效之间关系的调制作用确实存在：在高技术发展和市场需求动态性情况下知识获取、信息分发和组织记忆的边际贡献分别大于低动态性情况下的各自边际贡献( p值均小于0 . 01 ) 。
This dissertation analyzes the problems in setting up the p2p network in detail and puts forward the solution to these problems , and finally researches the key technologies of the system in depth : the mechanism of communicating and routing , the infomation dispensing algorithm , the mechanism of multiple downloading and the mechanism of security authenticating 2 )设计了基于p2p技术的可生存性系统,详细分析了创建p2p网络可能存在的问题并且提出了解决方案,最后对系统的关键技术进行了深入研究:通信路由机制、信息分发算法、并发下载机制和安全认证机制。
In order to fulfill the research , we firstly measured ol by knowledge acquisition ( ka ) , information dissemination ( id ) , information interpretation ( ii ) , and organizational memory ( om ) , and ed by technological and market dynamics . in this dissertation , questionnaire was used as research instrument during the data collecting 为了研究这些问题，我们首先分别对组织学习和环境动态性进行了测度，用知识获取、信息分发、信息解释和组织记忆度量组织学习能力，用技术发展和市场需求动态性表征环境的动态性水平。
