摘　　要：采用两种不同的方法分别测量了双光束干涉法中两个虚光源之间的距离,并对两种方法对实验结果的误差影响进行了比较分析,分析表明两种方法各有优劣,分别适合不同类型的学生。Distance of virtual light sources is measured by two methods in biprism interference experi- ment. Experimental analysis and comparison of two methods are presented. The advantages and disad- vantages of two methods are pointed out. The result shows that two methods are suitable for different types of students respectively.
