在学习测量长度的过程中,经常会遇到一些不好直接测量或由于物体形状特殊无法直接测量的问题,如细铜丝的直径、圆柱体的周长、硬币的直径等,要解决这些问题,就让我们一起来学习几种特殊的测量方法.测多算少法由于测量工具精确度的限制,某些微小量无法直接测量,在测量时,可以把若干个相同的微小量集中起来,作为一个整体进行测量,将测出的总量除以微 In learning the measurement length, often encounter some bad direct measurement or due to the shape of the object can not directly measure the problem, such as the diameter of thin copper wire, the circumference of the cylinder, the diameter of the coin, to solve these problems , Let us learn to learn several special measurement methods.Multiple count less calculation method due to the accuracy of measurement tools, some tiny amount can not be measured directly in the measurement, you can put a number of the same tiny amount of concentration, Measure as a whole and divide the total measured by microseconds
