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。

The SPRD is used on zone systems when the automatic closing of various zone dampers can create an excessive increase in air pressure and velocity throughout the duct system.
SPRD旁通阀是当各种区域风门自动关闭时用在区域系统中，可以在管道系统中增加空气压力盒速度。
