物理实验数据的处理与设计性实验让多数学生感到棘手,这就要根据实验的目的、原理,设计实验模式,结合被测量之间的相互关系,考虑实验结果的表示方法.常见的实验数据的处理的方法与技巧有:1.平均值法取算术平均值是为减小偶然误差而常用的一种数据处理方法.通常在同样的测量条件下,对于某一物理量进行多次测量的结果不会完全一样,用多次测量的算术平均值作为测量结果,实验误差最小.2.公式法及逐差法将实验数据直接代
The physical experiment data processing and design experiments make most students feel intractable, which is based on the purpose of the experiment, the design of experimental models, combined with the interrelationships between the measured, considering the representation of experimental results. Common experimental data Processing methods and techniques are: 1. The average method to take arithmetic mean is a commonly used data processing method to reduce accidental errors. Usually under the same measurement conditions, the results of multiple measurements for a physical quantity is not It will be exactly the same, using the arithmetic average of multiple measurements as the measurement result, the experimental error is the smallest. 2. The formula method and the subtraction method will directly substitute the experimental data.
