Its application to SPC circuits gives the same results as those obtained by the state-space average approach, which is proposed by Middlebrook and Colk, but our approach is also in the form of CMNA.

在分析方面，通过应用加权平均和小信号近似手段，我们建立了KL平均法，导出了开关变换器电路的S域分析的紧凑型改进节点方程，为人们应用拉普拉斯变换这一得心应手的工具来研究这类周期性开关电路提供了又一种方法。

This is achieved with a crosspoint switch that has a nonblocking path for each card in either a 4-by-4 or 16-by-16 matrix for a four- or 16-slot chassis, respectively.

这是利用一个交叉点开关实现的，对4插槽或16插槽的底架而言，该开关分别以4×4或16×16的矩阵形式，拥有每块卡的一条无阻塞通道。

Recently,the control of power supply of high frequency switch has been developed towards the "high refined and cuspidate" direction.Although the parts of apparatus have small volume and refined precision,the Electro Magnetic Interference and radiation are much stronger than before.

现在的高频开关电源控制已向&高、精、尖&方向发展，这些器件体积小、精度高，但电源内部的电磁干扰、辐射比原来更强了，为了使高频开关电源在预期的电磁环境下能正常工作、无性能降低及故障，并对电磁环境中的任何事物不构成电磁干扰，必需对其进行电磁兼容。

A new trigatron with a discal trigger electrode has been tested on its trigger characteristics.And the effects of different polarity combinations,trigger pulse amplitudes and trigger resistances on trigger characteristics of the trigatron have been derived.

对采用盘状触发电极的新型触发管开关的触发特性进行了实验研究，得到不同极性组合、不同触发电压幅值和不同触发电流条件下开关的触发特性实验结果。

Disconnector is a sort of high voltage switchgear without special arc-extinguishing device.

隔离开关是一种没有专门灭弧装置的开关设备，是我国西北电网建设第一条750kV线路的重要设备之一。

The comparably slow operation of a disconnector leads to sparking during closing and opening in the contact gap.

由于隔离开关的开关动作相对较慢，在断开和闭合的过程中，触点间隙中会产生火花。

Further, eliminating the air-exposed disconnector contacts also provides for lower maintenance and higher switchgear reliability.

此外，取消裸露在空气中的隔离开关触点，还可以减少维护次数，提高开关设备的可靠性。

The insulation of apparatus in the power system is often broken by the very fast transient overvoltagewhich is caused by the operation of disconnector in gas insulate substation In this paper, a new idea for the suppressing VFTO by ferrite is put forward, and the characteristic of ferrite is analyzed.

GIS中隔离开关操作时产生的特快速暂态过电压对电力系统及其设备的绝缘具有巨大的破坏力，本文提出了采用铁氧体来抑制GIS中隔离开关操作时产生VFTO的方法，分析铁氧体抑制VFTO的优点，对VFTO的抑制效果进行了实验研究和仿真分析，探讨了具有理想抑制效果的铁氧体参数的具体要求和对理想抑制参数的铁氧体尺寸的估算方法。

The static contact of earthing switch is fixed on the conductive pipe of disconnector. The dynastic contact is installed on the end of earthing knife in the base.

接地开关静触头固定在隔离开关的导电管上，动触头安装在底座上的接地闸刀钢管的端部。

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％。
