It overcomes the shortcoming that the theoretical research is only emphasized in the past while the combination with practical application is ignored . through this technology users can not only customize their own security tactics and application protocols but also reach a seamlessly utilization between platform and application 它克服了以往只强调安全理论研究而忽视实际应用的缺点，用户不但可以定制自己的安全策略和应用协议，而且能够实现平台与应用的完美结合。
Yet since snmp agent is part of snmp protocol implementation , and the protocol is greatly standardized , thus demanding a lot of labor and material resources to develop its development platform , most domestic device producers depend on foreign protocol development platforms to implement snmp agent in their own products 但是由于snmp网络管理代理软件是snmp协议实现的一部分，而协议具有很强的标准性，而且在开发协议实现平台时，需要花费较大的人力物力资源，因此大部分国内设备厂商都依赖国外第三方的协议开发平台来实现自己产品中的snmp代理功能。
Finally , the constraint dimensions of combined entity can be get with that formula . to prove correctness of this approach , the development system is based on autocad system , we introduced object - oriented technology including objectarx and visual c + + in the prototype system , the system achived the aim of solution the constraint dimensions of combined entity 井以obectarx和msualch为开发工具，利用面向对象的技术、基于auocad为实现平台，完成组合体的尺寸约束解的推理求解的实现，以对本文提出的尺寸约束解的推理求解的方法予以验证，论证了本方法的正确性。
According to the aim of realizing the given track , setup the input system of trick , the machine setting system , the imitate system , the program setting system and the trick check system . these systems make up for the shot of the original program of pmac , also provide the batter environment for realizing the given trick 以实现给定轨迹目的,在上位机控制系统中分别建立了相应的轨迹输入系统、机构设置系统、仿真校验系统、程序设定系统和轨迹检验系统,这些系统的建立在很大程度上弥补了pmac产品提供的原有程序pewin的不足,为本试验台创建了良好的轨迹实现平台。
