康普顿效应与拉曼散射的对比研究

光在传播过程中如果遇到小颗粒物质被散射后频率发生改变的现象其实是光与这些小颗粒物质碰撞的结果,都是光和物质的相互作用.康普顿效应是X射线光子与电子碰撞的结果,是光同原子之间的相互作用;而拉曼散射是可见光与分子碰撞的结果,是光同分子之间的相互作用。简要介绍了它们的历史发展过程,阐述了两者的原理,并就其原理和在实际应用上进行了对比研究,有助于我们更好地理解和掌握光与物质的相互作用理论。

Comparative Study on Compton Effect and Raman Scattering

The phenomenon that light's frequency has changed is the result of collision of the light with micro-particles when it is scattered through some matter.Actually,it is the originated from interaction of light and matter.Compton effect is caused by the collision of the X-ray photons with the electrons or the interaction between photons with atoms,while Raman scattering is formed from the collision of the visible light photons and molecular or the interaction between photons with molecular.Their process of historical development is introduced briefly,their fundamental principles are elaborated,and comparable investigations in pratical applications are conducted.It can help the undergraduate students to understand and grasp the interaction of the light and the matter.
