摘要
以大学物理实验中的具体实验项目为基础,提出了恒定系统误差对测量结果的影响,剖析了大学物理实验项目中的几个典型实验的系统误差的来源,提出了削减恒定系统误差的实验技术手段,即:交换法、代替法、异号法、避开法、求差法,并对这5种方法在具体的实验项目中削减恒定的系统误差进行了阐述。
Based on the several particular experimental items of physics experiment in college, the influence of constant systematic error on the measurement result is put forward, and the origin of the systematic error of the several typical physics experiment is analyzes. And the several experimental technical methods of reducing constant systematic error are introduced, i. e. , the exchange meth- od, the substitute method, the dissimilar sign method, the avoiding error method, the absolute dispersion method, and the five kinds of experimental technical method of reducing constant systematic error are introduced in order to reduce the influence of constant systematic error in practical physics experimental items.
