| 通过对多种微小电阻测量方法的研究，从测量时面对的问题、受到的干扰以及方法的不足入手进行改进。采用四线测量法设计的微小电阻测量装置，避免了测量馈线、温升、辅助元件等对测量精度的影响，进而实现精准地测量微小电阻的目的。经过试验从实验数据可直观地看到测量误差减小，证明做出的改进对精确测试微小电阻有实用意义。 |
| 英文摘要: |
| A variety of small resistance measurement methods are studied in this paper and improvement suggestions are proposed to solve the problems and interferences in measurement, and the lack of methods. A small resistance measurement device based on the four-line method is adopted to avoid the effects of the feeding line, the temperature and the auxiliary elements on the measurement precision, so as to improve the measurement accuracy of the small resistances. According to the experimental data, it can be directly found that the measurement errors are reduced, and it is verified that the improvement has practical significance on accurate testing of small resistances. |
