【摘要】 光在溶胶中的二次散射、反射式散射衰减和发散形散射光柱等现象是用单色激光照射卤化银溶胶时观察到的新现象,从这些现象中反映了影响散射光强度的各种因素。由于实验所用器材简单,操作安全,很适合教学演示。将卤化银溶胶对光的散射现象的观察,引入《大学化学》基础课教学,通过归纳总结、正确理解散射强度公式,取得了很好的教学效果。更多还原

【Abstract】 When monochrome laser indicators irradiate the sol of silver halides,we can observe the scattering phenomena including secondary scattering in sol,scattering attenuation of reflective light,and divergent scattering beam. These phenomena reflect the various factors affecting the intensity of scattering light. Because of simple equipment used in the experiment and safe operation,it is suitable for teaching demonstration. We have introduced the observations for light scattering in the sol of silver halide into the teaching of the basic course of university chemistry,and have obtained the very good teaching effect through the summarization and the correct understanding of the scattering intensity formula.更多还原
