例句與造句

1. 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對微腔激光器的閾值進(jìn)行研究，得到如下結(jié)論：在沒有無輻射躍遷時，激光器的泵浦速率只需恰好補(bǔ)償光子向腔外的逃逸速率，輸出光強(qiáng)隨著輸入泵浦光強(qiáng)性線增加，實(shí)現(xiàn)所謂的“無閾值”激光器。
2. It's difficult to find photon velocity in a sentence. 用photon velocity造句挺難的
