摘　　要：在量子光学中,用电磁感应透明的方法使光速变慢,甚至减慢到0,是现在光学研究的一个重点 本文从另一个角度,用经典电动力学这样的宏观物理方法,近似求解了上述的量子光学中非常重要的问题,并且与实验结果能很好地相符.开始从经典电动力学中的折射率入手,由此导出原子极化率与波速的关系,从而最后求出折射率与波速的关系,理论结果与实验中所测出的数据完全一致.In quantum optics, it is well known that Electromagnetically Induced Transparency can make light slowed down, even to zero. It also is an important field in nowadays research in quantum optics. This article develops a new way to study the phenomenon by classical electrodynamics. It solves the important problem by classical way instead of quantum way. Moreover, it fits the results they have got in the recent experiments. At the beginning, we get the refractive index by classical electrodynamics, then we get the relation between atomic polarizability and light frequency. At last, we could get the relation between refractive index and wave velocity. And the data from theoretical deduce are the same as them in the recent experiments. 
