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。

Other evidence for severe lateral velocity change across the fault zone lies in hypocenter bias and nodal plane distortion for earthquakes on the fault.

这种断层带上的侧向速度急剧变化还有其它表征，诸如震中定位的偏移、地震节平面的变形等等。

Last year, scientists using a technique called helioseismology, probed the Sun's interior, revealing that currents of gas at the base of the convective zone change velocity every 16 months.

While this is a pretty wide zone, considering the velocity of the move up, it could take all 30 pips to slow it down.
