中学物理实验中,系统误差是普遍存在的,在给定的实验目的和要求的情况下,系统误差既是我们正确选择实验途径(或方法)的重要依据,也是我们正确分析实验结论的重要一环。近年来的高考中已屡次触及到这方面的问题,这里我们借助几个主要实验中系统误差的分析,讨论一些方法,抛砖引玉,以期得到同行们的指教。系统误差的特点是偏在真值的一侧,它是由于仪器的粗糙、原理或方法的不完善等原因造成的,下面我们分别讨论。
In the middle school physics experiment, systematic errors are ubiquitous. Given the purpose and requirements of the experiment, systematic errors are both an important basis for the correct selection of experimental approaches (or methods) and an important part of our analysis of experimental conclusions. . In recent years, college entrance examination has repeatedly touched on this issue. Here we use the analysis of systematic errors in several major experiments to discuss some methods, and to inject ideas to gain the advice of our colleagues. The system error is characterized by the side of the true value, which is caused by the roughness of the instrument, the imperfection of the principle or method, etc. We discuss them separately below.
