摘要
通过对电桥测电阻实验中的测量方法的研究,根据测量方法中遇到的检流计电流改变方向及分区间测量的问题,引入高等数学中的零点定理进行叙述,将理论知识与实际操作结合起来,提高对实验及操作的进一步认知。
Introducting the Nullstellensatz of higher mathematics to base on the questions of changing direction of galvanometer current and district measuring through the research of the measurement method in electronic-bridge.Combining theoretical knowledge and practical operation to improve the further cognitive on experiments and operations.
