摘要
介绍了伏安内接法测电阻、电流补偿法测电阻、电压补偿法测电阻的原理,并说明了什么是正交试验设计法,而且以这三种测电阻方法为例详细介绍了正交试验设计法在大学物理实验方案选择中的应用。
Resistance measurement principles including volt-ampere internal connection,current compensation method and voltage compensation method were introduced and the orthogonal experiment method was elucidated in this paper. The orthogonal experiment method used to select the physics experiment schemes was introduced in detail according to the above three methods.
