As metastable atoms deexcite, the vaporvelocity and temperature increase, the peak value of the velocity distribution function shifts rightward, and the half width increases.
亚稳态原子消激发，使蒸气宏观速度增加，温度增加，所以使速度分布函数峰值右移，半宽度增加。

The atomic density and velocity distribution in the laser excitation zone is very important for the atomic vapor laser isotope separation (AVLIS).
在激光同位素分离中，激光作用区内原子的密度和速度分布对分离过程有重要影响。

Investigation was showed that the vibration of solvent vapor cooler was caused by excessive flow velocity and improper shell structure.
