The influence of impulse voltage waveshape on particle-initiated breakdown voltage of a GIS system in SF6 and SF6/Air mixtures is reported. The results are compared with the characteristics of air gaps. For the SF6 gaps, breakdown voltage depends on wave-front duration but almost independs on wavetail duration. For the gaps in SF6/Air mixtures, the influence of impulse waveshape also depends on SF6 contents and electrical field non-uniformity

作者研究比较了正极性冲击电压波形对SF_6、空气、SF_6/空气的 GIS 电极装置由固定导电微粒引发的击穿电压的影响，结果表明：SF_6间隙的击穿电压受冲击电压波前时间长短的影响较大，而与波长的关系不大，当采用SF_6/空气混合气体时，则这种影响随SF_6含量增大而愈明显，并与电场不均匀程度有关。

First, the effects of magnetic RAM relaxation time and the rise-time of incident pulse signal on reflection signal are discussed, the relationship between the rise-time of incident pulse and relaxation time based on the energy of reflection signal is revealed. Then, the effects of magnetic hysteric, susceptibilities and saturation upon reflection signal are analyzed, the results reveal the reflection of RAM target and UWB signal design. In the meantime, dielectric relaxation time effect about dielectric RAM target is analyzed simply, and the effects of relaxation time and the width of incident pulse upon reflection signal are probed. Finally, a few RAM targets are measured in the chamber using the impulse radar experiment system which is developed by the team of anti-stealth impulse radar on Department of Electrical Engineering, National University of Defense Technology. The experimental results show the similarity of the rule of echos with the theory. From the compared results of different tagets, we concluded, compared with 15% wideband sinusoidal signal, the impulse signal has increased 10～12dB energy from the same loaded RAM target; this, in turn, shows the nonlinear effects of RAM to the echoes, and the potentiality of the impulse signal to RAM targets.
