摘要
对导体截面积为1.5mm2的铜导线进行导体电阻值的测量,在铜导线上重复测量10次。根据 计算公式,计算出20℃和1km长度时的导体电阻,确定标准不确定度,获得测试报告结论。
To have measurements on the copper conductor wire with sectional surface area of 1.5mm2 for its resistance value is to make repeated measurements for ten times on the copper conductor wire. According to calculation formular. calculate the conductor's resistance value at the length of 1km and the temperature at 20℃. to determine standard uncertainty degree, so as to obtain test rcpart conclusion.
