摘要

周围气体的压力。在1torr的压力下产生半径约3cm的半球形发光等离子体,而气体击穿主要发生在10torr以上的压力下。等离子体具有薄壳结构。壳体前部的位移与时间的五分之二次方成正比。发光等离子体被从样品中喷出的原子所产生的冲击波所激发。

Blast Wave Generation by the Bombardment of TEA CO2 Laser at Low Pressures
pressures of surrounding gas. A luminous plasma with a hemispherical shape of about 3 cm radius is produced at the pressure of 1 Torr, while the gas breakdown takes place predominantly at pressures of above 10 Torr. The plasma has thin shell structure. The displacement of the front of the shell is proportional to the two-fifths power of time. The luminous plasma is found to be excited by the blast wave produced by the atoms gushed from the sample.
