摘要
利用交流电桥可以精确测量电容器的电容。由于该电桥结构复杂,对测量结果的影响因素是多方面的。本文探讨了对测量结果的不确定度的评价方法,试图完善交流电桥实验的教学内容。
By using alternating current bridge we can exactly measure the capacity of capacitor. Because the structure of current bridge is complex, there are various affecting factors to the result of measuring. This passage discusses evaluating methods of uncertainty in measured results, in order to improve the teaching content of alternating current bridge experiment .
