In order to make clear the phenomenon of current zero in the arc-quenching chamber of deion plates, the process of dielectric recovery and reignition of short arc between iron plates is investigated, and then the dielectric recovery strengths of various chambers are measured and compared. The different characteristics near current zero in the deion plate chambers are also analyzed based on experiments in the paper.

为弄清栅片灭弧室内电弧电流的过零过程，专门研究了不同条件下栅片间低压短弧的介质强度恢复过程和电弧重燃过程，然后测量了多纵缝和栅片灭弧室的介质恢复强度，对比了它们的熄弧性能，在试验的基础上，分析了栅片灭弧室中电弧电流的过零特征。

Explicitly, they are consist of three classes: If H is semisimple, then H k* for some finite group; If H is not semisimple and the characteristic of k is zero, then H is isomorphic the dual of the cross product between one so called Andruskiewitsch-Schneider algebra and a group algebra; If H is not semisimple and the characteristic of k is not zero, then H is isomorphic the dual of the cross product between one special algebra and a group algebra.

具体地讲，它们共(来源：5fbfA02BC论文网www.abclunwen.com)分三类：①如果H是半单的，则H同构与一个群代数的对偶；②如果H是非半单的并且基础域的特征是0的话，则H同构一个所谓Andruskiewitsch-Schneider代数与一个群代数交差积的对偶；③如果H是非半单的并且基础域的特征不是0的话，则H同构于某个特定代数与一个群代数交差积的对偶。

The inverse time delay characteristic is adopted by the basic zero-sequence over-voltage protection. On the basis of the analysis of the transient negative current, a compensated voltage can be generated with multiplying the rms value of the negative sequence transient current of the feeder by a settable compensated reactance, then combined with the magnitude of the zero-sequence voltage to consist of the compounded compensated voltage, which can be utilized to revise the characteristics of the inverse time-delay.

其基本保护采用零序过电压保护，动作时间采用反时限特性；在分析接地故障负序暂态电流分布特点的基础上，利用线路负序电流暂态有效值与一个可整定的补偿电抗相乘，形成补偿电压，并与零序电压幅值合成复合补偿电压，利用该电压对基本的反时限动作特性曲线进行修正，使零序过电压保护具有选择性。

That's what Bhrama Sphuta Siddhanta was. Written by astronomer Bhramagupta (598-665), it included chapters on both zero and negative numbers, arithmetic rules for zero and positive and negative numbers.

The string should not contain any ascii control characters such as carriage returns, linefeeds, tabs, or backspaces. windows displays these control characters as boxes or solid blocks. textout does not recognize a zero byte (or for unicode, a zero short integer) as denoting the end of a string.

字符串不应该包含任何 ascii 控制字符，比如回车键，换行键，制表符或退格键。windows 将这些控制字符显示为框或实心块。textout 不会把零字节（或者对于 unicode，是零 short integer）看作是字符串结尾的表示。

If the result is less than zero, the result is clamped to zero.

如果这个结果小于0，将固定为0。
