逃逸速率 meaning in English

escape rate

Adopting the amendatory rate equation , the threshold of the micro - cavity has been studied and the conclusion is shown as following : if there is not non - radiation transition , the pump velocity just need to compensate the photon velocity escaped from the cavity , and the intensity of output light will direct ratio to the intensity of input light then we got a micro - cavity laser with no threshold
采用修正的速率方程对微腔激光器的阈值进行研究，得到如下结论：在没有无辐射跃迁时，激光器的泵浦速率只需恰好补偿光子向腔外的逃逸速率，输出光强随着输入泵浦光强性线增加，实现所谓的“无阈值”激光器。
