跃迁率 meaning in English

transition rate

First , it is shown that the slope of the effective potential increase or decrease faster than the current . all of these facts indicate that the current and the slope are not simply linear relevant . second , the results show that the current and the slope of the effective potential change simultaneously when the temperature is in a certain range
计算结果表明： ( 1 )跃迁率很小时几率流和有效势的倾斜随着跃迁率的增加而增加，当跃迁率达到一定值40左右时，两者几乎同时达到最大值，跃迁率大于某一定值时，两者随跃迁率的增加又同时减小。
