| Abstract: | The different views were proposed about the classical theory that wave row length is equal to the coherent length.Base on the dates of experiment,the difference between a wave row length and the coherent length was analyzed from the atomic spectroscopy angle,and the applicable scope of two kinds of definitions coherent length of coherent length was given. |
