Near the critical point of the RLC-circuit, the residual voltage waveform changes form non-oscillating attenuation mode to distinct across zero oscillating mode when the peak current increases.

在RLC回路临界点附近，随着冲击电流峰值的增大，残压波波尾从非振荡衰减过渡到大幅度的过零振荡；

Safety helmet use caused no attenuation of critical traffic sounds, no limitation of pre crash visual field, and no fatigue or loss of attention;

头盔不会造成对关键交通音响信号的听力衰减，不会造成撞前视觉限制，不会导致疲劳和记忆力不集中。
