参量互作用 meaning in English

parametric interaction

Based on acousto - optical coupled wave equation , the momentum mismatch is modified and acousto - electro - optical coupled - wave equations are founded . for one - dimension acousto - electro - optical effects , the momentum mismatch caused by ultrasonic wave is replaced by the summation of mismatch caused by ultrasonic wave and mismatch caused by electric field
根据晶体中光场所遵循的麦克斯韦方程组,以及声场与光场间的参量互作用基本方程出发,在声光耦合波方程的基础上,系统地建立了声电光效应的耦合波方程理论。
