摘　　要：电线电缆是一项重要的电气参数,其质量直接影响着国民经济和人民的生活、健康、财产的安全。为了验证电线电缆材料的可靠度,提前预防安全事故的发生,需要对电线电缆的导体电阻进行精确的测量,而受地域、环境、人员、设备等因素的制约,目前我国测量机构的测量能力与水平并不统一。结合标准、规范的要求和实际的测试工作,论述了测量方法、测量的影响因素和相应的改进措施。The metal material tension test is the most important content testing its quality and production process.Various index parameters obtained during testing process are a key factor reflecting mechanical properties of metal material,however,in actual teasion test,its test result and test parameters can be under the influence of many factors,making accuracy of the test sample,tester calibration,holding method correctness and tension rate control produce marked influence on the test results.Making process of the test sample must comply with strict standard in order to ensure the whole material pwerformance.
