摘　　要：在普物实验中,分光计的调节和使用作为一个经典的实验项目被普遍采用,但在其调节过程中往往带有一定的机械性和偶然性,对初学者有较大的困扰。针对关键的细调环节,通过对渐近法调节原理的探讨,从理论上得出了反射镜法线和望远镜光轴偏离程度及调节到位情况的直接判据,可实现反射镜和望远镜的分离调节,使学生在调节中能真正做到"知其然,知其所以然",优化调节途径,有利于初学者快速掌握分光计调节的原理和技巧。The adjustment and usage of spectrometer is a typical experiment in the college physics experiments, but there is always a great puzzle for beginners for its mechanical process and accidental results of adjustment in some ways. In regard to the significant step of fine adjustment, the direct criteria of the degree of the deviation and adjustment of the reflector normal and telescope axis were obtained in theory according to the analysis of asymptotic adjustment. Thus, the spectrometer adjustment can be optimized by adjusting the reflector and telescope separately. Besides, it will help students to understand and master the principles and skills of adjustment better.
