部分吸收 meaning in English

fractional absorption
partial absorption

Due to the inevitable absorption of crystal window , the crystal window will be distorted even burst while the power of high energy laser apparatus is several hundred thousand watt even mega - watt , so the quality of laser beam will be influenced and the laser apparatus will not work properly
由于晶体材料窗口不可避免的部分吸收作用，对于目前几十万瓦甚至兆瓦级的高能激光器来说，晶体窗口会产生热畸变甚至炸裂，从而影响输出光束质量甚至使激光器根本无法工作。
Because of the intrinsic fractional absorption of the laser energy with the conventional solid output windows for high energy lasers ( hel ) , the optical quality will be degraded , or the overall hel system cannot run at all when the laser energy are far higher , or the system runs longer time
然而，由于高能激光器传统的固体输出窗口具有不可避免的部分吸收作用，因此，当输出激光功率很高，或激光器长时间工作时，固体输出窗口就会产生热畸变、甚至炸裂或被击穿，从而影响输出激光的光束质量或使高能激光器根本无法工作。
