| 摘 要： | 针对高校教材《普通物理实验》中液体表面张力系数的测定实验存在的一些问题,进行了认真分析,指出传统实验前后所测量的一些物理量不是等精度测量,因而有必要对实验原理和公式进行修正。改进型焦利氏秤,在载物台下装有测量机构,实验测量方法有所改变,实验思路更加明确,并经实验比对,使用改进型焦利氏秤做此实验,不仅操作和计算简便,而且所得结果更接近公论值,取得了良好的效果。

| Abstract: | As there exist some problems about measuring surface tension coefficient of liquid in the experiment in college textbook "General Physics Experiment",the authors have made serious analysis and found out that some physical quantities are not unanimous and not identical accuracy measurement before and after the traditional experiment.As a result,it is quite necessary to revise the experiment principle and formula.For this reason,the authors themselves design an improved Jolly balance by installing measuring device under the load table.To some extent,the measurement method of experiment has been improved,and the view of experiment has become more definite.By the comparison of the experiment,it is not only convenient for people to operate but easier to calculate by using the improved Jolly balance.The result of the experiment is closer to the standard,and then good effect is acquired. |
