测量是物理实验的重要内容,读数是测量的重要环节。《考试说明》中要求学生熟练掌握的13种基本仪器,除打点计时器和滑动变阻器外都涉及到读数问题。因此我们对仪器的读数十分重视,归纳和总结了多种方法,公式读数法便是其中常用的方法。比如对十分度的测量仪器我们常常这样读数:用目力将指针所在的分度区间分成10等份(即分度值为10),然后估读指针所指位置在其中的第K
Measurement is an important part of physical experiments, and readings are an important part of measurement. The 13 basic instruments required by the students in the “Exam Description” are related to the reading problems except the dot counter and the sliding rheostat. Therefore, we attach great importance to the reading of the instrument, and summarize and summarize a variety of methods. The formula reading method is one of the commonly used methods. For example, we often read readings with very high degree of measuring instruments: with the aid of eyesight, divide the indexing interval into 10 equal parts (that is, the dividing value is 10), and then estimate the number K in which the pointer is located.
