But it is not enough for a simple ofdm system to resist multi - path - fading . the multi - path - fading can be resisted efficiently and system ' s error bit rate performance can be improved if we combine ofdm , a high - rate modulation technology , with mimo 但是靠单纯的ofdm来抗多径是远远不够的，将无线局域网中的高速调制技术ofdm和mimo技术相结合，就可以有效地抗多径衰落，改善系统性能。
When it is discharged at high - rate , the distributions are also the most uniform at the end of the discharge . this indicates that the positive plate with the red lead has the better discharge performance than the other two kinds of positive plates 含红丹的正极板在化成初期电流密度和电位的分布最均匀,极化最小,在高倍率放电结束时,其电流密度和电位分布也最均匀,表明含红丹的正极板的放电性能比其它两种正极板好。
Many advantages make optical fiber suitable used as transmission medium of high - rate broadband services , such as broad transmission band , large capacity , low loss , strong immunity to interference etc . among optical access network , passive optical network ( pon ) is paid more attention throughout the world . it offers easily upgraded and low cost of lay , ope ration and maintenance . especially passive optical network based on atm ( atm - pon ) integrates the capability of supporting multiple qos services with atm and transparent transmission with pon 在光纤接入网中，无源光网络( pon )由于不采用有源节点、敷设和运行维护成本低且成本共享、对业务透明、易于升级等优点而备受世界各国的关注，特别是以atm为基础的无源光网络( atm - pon ) ，由于结合了atm多业务、多比特率的支持能力和pon的透明宽带传送能力，将成为实现未来宽带接入乃至最终实现ftth的重要方式。
Based on an investigation to rural association cooperation , this article depicts a current phenomenon of the fast development of rural association cooperation , analyzes a cooperative relationship of association peasant households , the existing problems and the motive of unilateral contract fraud in association cooperation by the basic principles and methods of game theory , and gives a theoretical interpretation and a model of association households cooperation as against a reflection of high - rate phenomenon of contract - breaking 摘要文章基于对农村协会合作的调查，勾勒了当前农村协会合作快速发展的现象，分析了“协会农户”合作关系，应用博弈论基本原理和方法，分析协会合作存在的问题和单边“履约欺诈”动机，对于反映违约率高的现象给出“协会农户”合作的模型，作出理论解释。
Combined with development of the products , the research emphasis in this paper is focus on the studies of the high - rate discharging performance at different temperature . 1 . in the research of the discharge performance with high rate , the results of different effects including thickness of positive electrode , materials of hydrogen storage alloy , concentration of the electrolyte and separators 论文在实现研究目标的过程中，结合产品的研制，重点对电池的高倍率放电性能和温度性能进行了研究：一、在提高电池大电流放电性能的研究中，比较了不同正极板厚度、不同贮氢合金材料、不同浓度电解液及不同材料隔膜等对电池大电流放电平台的影响，并从电极反应动力学和多孔电极的角度分析了极板厚度对电池高倍率放电的影响。
The normal user must go through the access network and backbone to access the internet via icp there are always high - rate and broadband lines connected to the backbone , the backbone of telecom can provide wide enough bandwidth for all the data transmission as more and more optic fiber with wdm and dwdm technologies have been paved . but " the last mile " from user ' s home to central office is still narrow - band and analog , which becomes bottom - neck of the communication subnet preventing it from being widen 一般用户使用internet时要经过接入网，电信主干网，最后达到icp ( internetcontentprovider ：因特网内容提供商) 。其中icp一般有着高速宽带的线路与主干网相连，而主干网由于波分复用或密集波分复用的光纤技术的大量使用，使得其可提供足够的带宽使用，但是，接入网? ?从用户家庭到电信网的局端的这“最后一公里” ，仍然是窄带的、模拟的，这“最后一公里”就是电信网宽带化的瓶颈。
