First, the S-CDMA-HFC system with integrated traffic is introduced and the method of traffic integration is given. Second, the upstream channel capacity of the S-CDMA-HFC system with integrated traffic that has the same rate is analyzed. The chronoff limit and Gaussian approximate equation of the upstream channel cutoff probability are derived. Third, the impact of the selection of the line transmission rate on the upstream channel capacity of the S-CDMA-HFC system with integrated traffic is discussed in detail. The cutoff probability and throughout equations of the upstream channel with different integrated traffic are derived. Fourth, the impact of the power control error on the capacity is discussed. Results show that the power control error will degrade the upstream channel capacity and have different influence on the different traffic. Finally, the capacity requirement of the initialization process is raised. Analytical results show that the initialization process will impact on the capacity slightly.

首先，简单介绍了综合业务S-CDMA-HFC系统，给出了业务综合的方法；然后，分析了具有相同码率的综合业务条件下的S-CDMA-HFC系统上行信道容量，导出上行信道中断概率的切尔诺夫上限和高斯近似公式；然后，详细讨论了基本传输速率的选择对综合业务S-CDMA-HFC系统上行信道容量的影响，导出了不同业务综合条件下上行信道的中断概率和吞吐量公式；然后，讨论了功率控制误差对综合业务S-CDMA-HFC系统上行信道容量的影响，结果表明功率控制误差会使上行信道容量下降，且对不同业务的影响程度是不同的；最后给出了初始接入的容量要求，分析结果表明初始接入将对综合业务S-CDMA-HFC系统上行容量带来影响，但不明显。

At present, our country majority cities have already established the many kinds of traffic signal control system, at the same time, the road intersection simple point signal control was still the main signal control way, timed control occupies proportion bigger, undulates a bigger road intersection in some traffic flows, to realize the signal fuzzy control to be imminent.

目前，就我国大多数城市而言，已经建立了多种交通信号控制系统，与此同时，交叉口单点信号控制仍是主要的信号控制方式，其中定时控制所占的比例较大，在一些交通流量波动较大的交叉口，实现信号模糊控制已迫在眉睫。

Reverse traffic can lead degradation of TCP performance. To resolve this problem, we analyze the impact of reverse traffic carefully, and obtain the relation between reverse traffic and TCP performance. We propose an approach of rate control optimized for unidirectional trip time, and design an algorithm for rate control, called Unidirectional Trip Aware Rate Control, UTARC.

针对反向数据流量会导致TCP性能下降的问题，本文详细研究了反向数据流量对正向数据流应答的影响，揭示了反向数据流量与TCP传输性能之间的联系，提出了面向单向延时优化的速率控制方法，并设计了相应的速率控制算法UTARC。

In order to study the influence of delays in right-turn traffic,this paper analyzed the characteristic of right-turn traffic on signal control intersection,on this basis,useing the mentality that the green and the red signal times' right-turn traffic study separately,proposed three models to calculate right-turn traffic delays on signal control intersection,has laid certain foundation for the appraisal of signal control intersection's service level.

为了研究右转车流延误的影响，本文分析了信控交叉口右转车流运行特征，在此基础上，采用将绿灯信号时间和红灯信号时间的右转分别进行研究的思路，提出了计算信控交叉口右转车流延误的三种模型，为评价信控交叉口的服务水平奠定了一定的基础。

It also points out that an airline's safety record is not a criterion for renewal of its licence. Nor is the maintenance of airports and air-traffic control systems keeping pace with the industry's expansion.

同时他们指出，航空安全记录并不能作为重新注册许可证的标准，同时维修养护费用和空中交通管制系统能够与航空业的扩张保持一致也不能成为判断的准则。
