1. Scattering and absorption both cause extinction of light; but in a negligibly absorbing medium, extinction would be primarily by scattering. 散射和吸收都会引起消光，但在一个可以忽略吸收的介质中，消光主要由散射造成。

3. This paper studies the relationship of infrared extinction effect of pyrotechnic agent with material granularities on the base of infrared extinction mechanism of smoke. 本文在深入理解烟幕微粒红外消光机理的基础上，研究了粒径因素与发烟剂遮蔽红外辐射性能的关系。
4. FIBERPRO's Polarization Extinction Ratio Meter, ER2000, measures the Polarization Extinction Ratio (PER), Polarization Angle and Power with high accuracy and fast speed. FIBERPRO的消光比测试仪，ER2000，可以快速高精度地测量消光比，偏振角度，和光功率。
5. Theoretic and experimental analysis indicate the improved system can avoid using the birefringent phase modulator, reduce the require of the polarizer extinction ratio and phase modulator. 理论和实验分析表明该新型结构能够避免双折射相位调制器的使用，使得系统降低了对相位调制器的要求，同时也降低了系统对光纤偏振器消光比的要求。
