KRA could not be applied to uncertain data directly because uncertain data has probability.

由于不确定性数据带有概率，KRA算法不能直接应用于不确定性数据。

Dr Kra usel and her colleagues boosted the power of their machine by strengthening its coil and speeding up the rate at which the capacitors dump their charge.

Krausel博士和同事们通过增加线圈的绕数以及提高电容器释放电流的速率，加大了他们的机器的功率。
