摘要
在大学物理实验中,有很多实验使用人工秒表计时,由于系统误差较大往往不能得到理想的实验结果,而经过改进采用数字毫秒表计时后,就解决了这个问题,使实验误差控制在百分之一以内。
In many experiments of college,second watch is still be used now by every person in laboratory for the measurement of time,desired results usually can not be got as a result of systematic error.However,it could be settled by using the digital millisecond watch,which can make the error of the experiment below 1 percent.
