n.險峻；陡度

So computing the difference of two-tape length of erased magnetic record can find out the lightning max steepness. 故計算兩條磁帶的消磁長度差可直接測出雷電流最大陡度。

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. 試驗觀測了高頻磁環(huán)對真空間隙擊穿所產生的陡波陡度的影響。
