If the power input varies throughout the operating cycle and the maximum value of the power input exceeds, by a factor greater than two the arithmetic mean value of the power input occurring during a representative period., then the power input is the maximum value that is exceeded for more than 10 % of the representative period. Otherwise the power input is taken as the arithmetic mean value.

如果输入功率在整个工作周期内是变化的,最大功率值超过了代表周期内输入功率算术均方根的两倍,则输入功率为占据10%以上典型周期内的最大功率值。否则输入功率为算术均方根值。# E+ b. t0 V1 A+ ^) \# B

简单地说就是,如果某个功率在10%工作周期以内都出现,而该值又大于工作周期内功率的算术均方根的2倍,则这个功率就是输入功率,否则就是算术均方根是功率。
