周期性地

The proposed scheme distinguishes real-time traffic and non-real-time traffics, and reduces the bandwidth assigned to non-real-time call connections to provide quality of service to real-time call connections if necessary. If there were not enough free bandwidth, the existing multimedia calls could gracefully. contribute a few bandwidth to decrease the CBP and CDP while they were still at an acceptable quality degradation level.

其次讨论了区分实时和非实时业务的带宽预留的呼叫接纳控制算法，对多种媒体业务分类与特性进行了描述并给出了仿真模型；在此基础上提出了一种新颖的基于测量网络状态的动态呼叫接纳控制算法，该算法通过限制实时业务的切换呼叫掉线率低于设定的门限值，并且周期性地调整预留带宽大小以适应快速变化的网络负载状态。

The Muslim Arabs in the north, who have run Sudan since it broke free from Britain in 1956, have little in common with their blacker-skinned Christian and animist compatriots in the south, whom they have periodically enslaved over the centuries.

自1956年脱离英国以来，北部穆斯林阿拉伯人就统治着苏丹。他们与南部黑皮肤的基督教徒和信奉万物有灵论的同胞们几无共性可言，周期性地奴役着他们几个世纪之久。

Based on the former studies, this paper promotes an innovation about this topic using new satellite altimetry data and hydrographic data along with numerical experiments: Firstly, the temporal variation of the deformation of Kuroshio accompanied by the periodically shed anticyclonic eddies from the Kuroshio bend is discovered; Secondly, the major mechanism of the anticyclonic eddy separating from the Kuroshio bend, which is the frontal instability, is brought forward and then proved; Thirdly, the factors with important impact on the periodical variation of the Kuroshio bend and the eddy shedding, which are the strength of the Kuroshio transport and the circulation in the winter SCS, are determined.

本文在前人工作的基础上，利用了最新的卫星遥感资料和海洋调查资料，通过数值模式的数值实验，得到了以下前人没有得到的创新成果：发现在吕宋海峡处黑潮的形变随时间变化，并伴有反气旋涡周期性地从黑潮主体中脱落；提出并证明了吕宋海峡黑潮锋附近的锋面不稳定是反气旋涡从黑潮弯曲中脱落的主要机制；确定了对黑潮弯曲周期性变化以及反气旋涡脱落有重要影响的物理因素是黑潮流量的大小及冬季南海局地环流。

By the late 1980s, the economy became overheated with increasing rates of inflation. At the end of 1988, in reaction to a surge of inflation caused by accelerated price reforms, the leadership introduced an austerity program .

这个时候的中国政府周期性地走回头路不时地再次加强中央的计划控制。1988年底时，作为对价格改革引发的通货膨胀的反应，中国领导层采取了经济紧缩方案(如减少消费，增加出口)。

It is observed that each of the N nodes of an undirected double loop network can be represented by its coordinates in Cartesian coordinate system as mod N.

在这部分，我们主要是利用无向双环网的N个节点中的每个点都可用平面坐标系中的坐标，采用mod N的方式表示，从而发现N个节点在坐标平面中周期性地出现。

The distributed phase shifters consist of a coplanar waveguide transmission line loaded periodically with MEMS capacitors,which provide variable phase shift through voltage control of the MEMS capacitors.
