peak time lag

Since many transformers do not carry continuous loads, advantage can be gained from the thermal time lag to carry higher peak loads without exceeding the temperature limits.

由于许多变压器并不带持续负荷，这就可利用发热时间的滞后来带上更高的峰值负荷而不至于超出温升的限定值。

The lag time of the flood peak behind the peak of heavy area rainfall is shorter in small river basins than that in large basins.

面雨量峰值出现时间与洪峰的出现时间之间存在着一定的滞后关系，一般是小流域滞后的时间短，而大流域滞后的时间长。
