“补差法”就是对某一个物理量进行补充以达到某个预想的标准,从而使某些棘手的问题得到有效快速的解决。一、物理实验中“补差法”的应用1.力学实验中“补差法”的应用为了提高测量物体长度的精确度,人们发明了游标卡尺,游标卡尺的工作原理,就是一种长度的“补差法”。游标卡尺就是通过游标尺一小格与主尺一小格的长度差确定测量精度,用来测量物体毫米以下的具体长度。 “Make up difference method ” is to replenish a certain physical quantity to achieve a desired standard, so that some thorny problems can be effectively and quickly solved. First, the physical experiment “make up the difference method ” 1 mechanical experiment “make up difference method ” application In order to improve the accuracy of measuring the object length, people invented the vernier calipers, vernier caliper works, is a length “Make up difference”. Vernier caliper through the ruler is a small grid and the main ruler to determine the length of a small grid accuracy, the object used to measure the specific length mm below.
