物理学是一门以实验为基础的学科.实验中常常遇到一些微小物理量的测量.为了提高测量精度,经常需要将这些物理量放大,或转换后放大再进行测量,我们把这种为提高测量精度使物理量的数值变大、作用时间延长、作用空间扩展的方法叫做物理量的放大法.以下就相关内容作简要归纳.一、螺旋放大(螺旋测微)用双缝干涉测定光的波长等实验装置中,其测 Physics is an experiment-based discipline. Experiments often involve measurement of small physical quantities. In order to improve the measurement accuracy, these physical quantities often need to be amplified, or after conversion, they are amplified and then measured. We have improved this measurement. The method of increasing the value of the physical quantity, extending the acting time, and expanding the acting space is referred to as the physical quantity amplification method. The following is a brief summary of the relevant contents. First, spiral amplification (screw micrometering) uses double slit interference to measure the wavelength of light and other experiments. In the device, its measurement
