Screening effect relys upon both absorptionloss and reflection loss.
屏蔽效果主要是靠吸收损耗与反射损耗。

Absorptionloss due to high harmonics of C-H vibrations, the primary loss factor in PMMA POF, was analyzed and calculated. And the results were consistent with measured datas.
Transmission electron microscopy creates images by shooting trillions of electrons through an object and measuring their absorption, deflection and energy loss.
