pulse absorption

As long as changes of voltage on the surface of the equivalent electret are measured during and after the absorption of a transient thermal pulse on one electret surface, the total charge and charge centroid in thin electret are obtained directly with this technique.

只要驻极体表面在吸收热脉冲的瞬间以及其后，测量出等效表面电压的变化，便可直接算得驻极体的总电荷量及其电荷重心。

It is an effective method that using short pulse laser to measure the backscattering of a remote target under test and analyzing trace gas distribution in atmosphere with differential absorption.

它是一种利用短脉冲激光测量远程待测目标的后向散射光，差分吸收式分析大气中尾气污染物分布的有效方法。

Absorption of GMAW pulse arc to Nd: YAG laser power

GMAW脉冲电弧对Nd∶YAG激光能量的吸收

Long-pulse laser has high total energy, but due to the low power density, K9 laser absorption is very small, so the damage is not significant.

而长脉冲虽总能量很高，但由于功率密度很低，K9对激光吸收很小，所以往往造不成显著损伤。
