n.险峻；陡度
So computing the difference of two-tape length of erased magnetic record can find out the lightning max steepness. 故计算两条磁带的消磁长度差可直接测出雷电流最大陡度。
Tests have been performed to investigate the high frequency magnetic rings influence upon the steepness of the transients produced by breaking down a vacuum gap. 试验观测了高频磁环对真空间隙击穿所产生的陡波陡度的影响。
