The waveform of differential current in each data window is divided into four parts averagely according to time, and the area-ratio among the four parts can be used to distinguish magnetizing inrush from internal fault current.

该算法以工频一周波为数据窗长，将数据窗内的差流波形按时间均分为4份，根据各份面积之间的比值来识别励磁涌流和内部故障电流。

The microsecond response time of power semiconductors allows them to limit fault current to low levels, and consequently limit the system energy that must be managed (i.e. dissipated).

在功率半导体微秒的响应时间使他们能够限制故障电流保持一个较低的水平，从而限制了系统的必须加以管理的能量。

Troubleshooting problems caused by faulty or non-existant reverse DNS can take considerable time and effort.

疑难解答问题所造成的故障或不existant反向域名解析，可需要一段相当长的时间和精力。

Engineering practice shows this detector can rapidly detect the fault of aerocamera,and shorten the fault obviation time,guarantee aerocamera work normally.

实践证明检测仪可快速有效的对航空相机进行故障检测，缩短排故时间，保证相机正常工作。

4 When evaporative cooling hydro-generator (generator/motor) is running off-centered instantaneously under accident condition, it shall be 20s if we multiply square of ratio between negative sequence current weightand rated current (pre-unit value) by allowed dissymmetric runtime t (I2/In)2t.

In this flow a tradeoff of multiple test methods is adopted, which includes structural test, functional test and parametric test. Using the test mode of"stop as finding the fault"and based on the position of the first failure, we can label the faulty chips into different bins.

该流程综合采用结构测试、功能测试、参数测试等测试方法，采取"发现故障即停止"的测试方式，根据芯片首次失效的位置对失效芯片进行Bin的分类，有效增强了分析的针对性，缩短了测试时间。

A frequency-domain research tool for calculating the initial amplitude,phase,frequency and time constant of fault transient components in complicated networks is developed.

为计算复杂电力网络故障暂态分量的初始幅值、相位、频率和时间常数，开发了一套新的频域计算方法和研究工具。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
