高斯场的实验证明——数字化实验应用举例

Experimental proof of Gauss field——The examplication of the application of digital experiment

高斯公式在物理学中有广泛的应用,体现了各种物理场扩散在方向上的均匀性和三维空间中的恒定性。学习和理解高斯公式对学习物理学的基本概念有着重要的作用,然而,对于基础物理教学来说,还没有一个实验能够方便地证明高斯公式在描述这些物理量的正确性。通过列举几个常见的符合高斯公式的物理量,简述其实验测量的难度,并使用数字化传感器测量光辐射的分布情况,验证高斯公式。

Gauss formula, wildly used in physics, reflects several types of physical field diffusion in the direction of uniformity and constancy of three - dimensional space. The learning of Gauss formula is important for understand- ing basic concepts of physics. However, there is no any experiment can conveniently proves the accuracy of gauss quantities in describing those physical fields. In this paper, several common physical fields in accordance with Gauss formula are listed; the difficulties of its experimental measurements are briefly introduced; and the distribution of op- tical radiation was measured to verify Gauss formula by using digital sensors.
