高中物理实验中常采用图像法分析处理实验结果,用图像法处理数据有精确度高,误差小,实验结果直观等特点,有时通过图像的形状还可进行实验的错误与误差分析,最常用的是一次函数图像。虽然在平时的实验中此法仅是供选择的方法之一,但由于此法对学生的综合能力要求较高,所以近年来的高考中有关此法的题型频频出现,下面就高中阶段涉及此法的实验进行一个归纳并举例分析。
High school physics experiments often use image method to analyze and process experimental results. Image processing methods have high accuracy, small error, and intuitive experimental results. Sometimes, the shape of the image can also be used to carry out experimental errors and error analysis. The most commonly used is A function image. Although in the usual experiment, this method is only one of the alternative methods, but because this method has a higher requirement for the students’ comprehensive ability, questions about this method have appeared frequently in the college entrance examination in recent years. The experiments of this method are summarized and analyzed by examples.
