What we re finding , though , is that many of the higher - level standards are aiming at smaller markets , where there does need to be an agreement , and it needs to be a public agreement , but it isn t something that will be universally adopted 但是，我们发现许多较高层的标准针对的是较小的市场，在那里确实需要一种协议，并且它需要成为一种公共协议，但这不是将普遍被采用的标准。
The nms in the telecommunication system must follow the rules of osi system and object - oriented system architecture . currently several solutions are adopted in the telecommunication nms interface . they are snmp protocol , api and some distribution techniques 鉴于当前电信网管系统必须遵循开放互连、面向对象的体系结构，这里分析比较了当前在电信网管系统中常被采用的接口的几种接口方案：标准的协议规范snmp和cmip 、开放的api和私有接口、 corba等分布技术。
Using the analytic method of finite elastic layer to calculate the transmission of the ground vibration , we get the displacement - time curve , acceleration - time curve and transfer function spectrum of ground under moving load , and analyze the result . in practice engineering calculation , this method is wildly used 对于振动在地基中的传播采用分层法的解析算法，得到了地基土在移动荷载作用下的时程分析曲线、加速度变化曲线以及在不同地质条件下的传递函数反应谱等，并对计算结果进行了分析，在实际工程计算当中，这一方法也是广泛被采用的。
At first , wireless channel and characteristic of radio propagation are investigated in order to learn them . then smart antenna , which will be adopted widely , is researched . finally , the space - time receiver technology under multipath slow fading channels and multipath fast fading channels is studied emphatically , this content is the core of this paper 因此，本文首先研究了无线信道及其电波传播特性，以期对无线移动通信的无线信道有充分的认识；接着研究了必将广泛被采用的智能天线技术(它能引进空间分集，抗信道衰落，并提高系统容量) ；最后，基于对信道的认识并把智能天线技术结合，着重研究了在多径慢衰落信道与多径快衰落信道下的空时接收机技术，这部分内容是本文核心。
