The ionization and dissociation of polyatomic molecules in femtosecond laserfield were studied in the article. 本论文的主要内容是利用飞行时间质谱仪来探测飞秒激光强场下气体小分子的电离解离。
The negative effect produced by ionization of the dielectrics is reduced with the phase factor of alternating electric signals. 利用交变电信号的相位项，降低由电介质电离而产生的负效应。
