preplasma meaning in Chinese

超前等离子体

This thesis is devoted to studying those issues relevant to the interaction of ultra - short ultra - intense laser pulses with overdense plasmas , including the generation and transport of relativistic electron beams , the generation of quasistatic magnetic field , the energetic ions production , and the influence of preplasma on electrons acceleration
本文的研究目的是：利用粒子模拟方法，对超短超强激光脉冲与高密度等离子体相互作用中高能强电流的产生和输运、准静态磁场产生、高能离子产生等物理过程进行研究。
