This phenomenon was explained with the avalanche ionization mechanism and the concept of the equivalent pulse was proposed.

进而利用雪崩电离的机制对实验现象给予了解释，并提出了等效脉冲的概念。

In order to study avalanche ionization mechanism, it is inevitable to deal with rates of electrons absorbing and losing energy.

研究雪崩破坏机理，必然涉及到电子吸收激光能量的速率和电子损耗能量的速率，这些都与电子和声子的散射有密切的联系。

Both the nature of avalanche ionization (ai) and the role of multi-photon ionization (MPI) in the studies of laser-induced damage have remained controversial up to now.

雪崩离化(MPI)和多光子离化(AI)的性质和作用，到目前为止依然存在争议。
