摘要: 在激光调阻机高精度可编程双电压源(DVS)中, 线电阻是影响测量精度的关键因素. 测量DVS在两种不同线电阻条件下的输出电压, 并用数理统计方法验证了输出电压与线电阻不相关, 即导线电阻与输出电压无关, 结果表明, DVS设计正确. 该方法可验证系统中两个物理量的不相关性. 

Abstract: The line resistance is the key factor for precise measurement in the dual high precision programmable voltage supply (DVS). The two sets of data were got by measurement under the condition of two different line resistances. The validating with statistics of the two sets of data was done, and the result of the DVS output voltage, which is independent of line resistance, was proved. It means the DVS circuit omits the affection of line resistance. The statistics method is valued for testing the physical parameters in system. 
