The adaptive setting on reclosing time is presented accordingto the analysis on transient energy across transmission bottleneck in the network.

通过对网络中输电瓶颈的暂态能量变化特点的讨论，提出系统在发生瞬时性故障情况下重合闸最佳时间的整定方法。

In the early 1920s, the development of automatic reclosing, protective relays, and means for automatic control of voltage made it possible for AC substations to be completely automatic.

二十世纪二十年代初期，由于自动重合闸，保护继电器及电压自动控制设备的研制，使交流变电站有可能完全自动化。

If the circuit breaker to disconnect the initial state, the circuit breaker reclosing, the electrical start.

如果断路器初始状态为断开，断路器合闸，电机开始启动。

If the circuit breaker to disconnect the initial state, the circuitbreaker reclosing, the electrical start.

如果断路器初始状态为断开，断路器合闸，电机开始启动。

Faster switching time is advantageous not only in terms of system stability, but also from the standpoint of minimizing possible equipment damage during the fault period, and allowing faster reclosing time.

快的开断时间不仅有利于系统稳定性，而且从降低故障期间设备损坏最小化以及对允许更快的重合闸时间也是有利的。

In these cases, the mode of singlepole reclosing was set, and when single phase grounded fault occurred at the transmission line, all of protection relay operated correctly, and three phases of one breaker directly tripped at one time, and this breaker was not reclosed.

详细介绍了华中某500kV变电站两起典型的重合闸不正确动作事故，即在单重模式下，输电线路发生单相接地故障，保护装置均正确出口情况下，其中一个线路断路器直接三跳，未重合。

By phosphorus incorporation, the gate oxide reliability can be enhanced.

经於磷的掺杂，能增加闸极氧化层的可靠度。

The study result indicated that the free vibration of the dam will be affect by opened hollow and pier added on dam.

研究表明考虑孔口和闸墩对大坝的自振特性有一定的影响。

For vibration mode-shape, this affect is moreseverity on high rank stage vibration than low. With opened hollow and pier added on dam,the frequency of vibration decline.

对于振型而言，这种影响对低阶振型比高阶振型大，考虑孔口和闸墩后，大坝的自振频率有所降低；在低阶振型中有一部分的排列顺序发生了变化，但这些变化不致使大坝的动力特性发生显著的改变。

A cold-water supply system consists essentially of a communication pipe、a meter box、pressure boosters、storage taks、a piping line、valves and water-dispensing fixtures.

一个冷水给水系统的基本组成是：引入管、水表盒、增压设施、贮水箱、管道、闸阀和配水器具。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
