摘要
介绍了在实验室中测大电阻的一种方法。依据欧姆定律，并利用灵敏电流计测出数据。被测电阻的实测结果标准误差小于００３ＭΩ，相对误差小于１％。
A method of measuring high resistance in laboratories is introduced based on the principle of Ohm's law and a fine currentmeter is used to measure the data.The result is obtained that the standard error is less than 0.03 MΩ and the relative error is less than 1%.
