Shock velocities in porous iron samples having different initial porosities have been measured using the pulse generation network.

通过脉冲网络法对不同初始孔隙度的多孔铁中冲击波速度的测量，结合多孔材料完全压实区冲击Ｈｕｇｏｎｉｏｔ方程，就初始孔隙度对冲击波在多孔铁中衰减特性的影响进行了研究。

Firstly,buffer subsystem,i.

首先需要引入缓冲网,将靠近内网的少量外网厂站详细建模,以保留外网重要的动态响应细节;其次应保留外网中对内网动态过程影响较大的发电机的详细模型。

This article profoundly analyses the impedance characteristic of buffer network which is used in the test of Insertion Loss of EMI power line filters in the case of load, especially, pivotal components of the buffer network, such as shield cable, resisted-circuit inductance are paid more attention to.

文章通过对EMI电源干扰滤波器加载测试系统的关键组成部分:屏蔽电缆引线,缓冲网络及其组成完整回路阻抗特性的深入分析,设计出一种适合于EMI电源干扰滤波器插入损耗测量加载额定工作电流的缓冲网络,该网络为被测设备提供额定电流的同时有效阻止被测干扰信号的分流。
