本文主要介绍国产Gx12M3系列同轴热敏电阻座与苏联M4—1(MTo—1)型标准功率电桥配合使用的实验结果及其误差分析。提供了实验数据,通过实验证明了国产同轴座与M4—1型桥配合使用时在零漂,读数稳定性及有效效率传递精度等方面优于苏联原配波导座,从而挖掘了M4—1型桥使用精度的潜力,恢复和扩大了M4—1型桥的使用范围,使其在科研生产中更好地发挥作用。 This article mainly introduces the experimental results and error analysis of the domestic Gx12M3 series coaxial thermistor base and the Soviet Union M4-1 (MTo-1) standard power bridge. The experimental data are provided. Experiments prove that the domestic coaxial base and the M4-1 type bridge are superior to the original Soviet wave guide base in the aspects of zero drift, reading stability and effective transmission efficiency, so as to excavate the M4-1 type Bridge using the potential of precision, restore and expand the scope of use of M4-1-type bridge to make it better in scientific research and production.
