摘要
分光计是光学实验中一种常见的重要的精密仪器。但分光计的结构复杂,调节繁琐,学生难以在有限的课堂时间内完成操作。本文根据多年经验归纳总结出一种简单、清楚的"三步逼近法",并进行了详细的理论分析。利用此法可以又快又精确地达到调节要求,从而可以提高实验效率。
Spectrometer is a kind of common and important precise instrument in optical experiment.The com-plicated structure and troublesome adjustment make it difficult for students to aright operate it in specified classroom time.According to the author’s years of experience, a simple and explicit “ three- step” adjustment method is summarized,and its theory is analyzed in detail.With the help of this method, adjustment will be re-alized quickly and exactly,the efficiency of the experiment will be enhanced.
