摘要

研究了1 gpa锰电阻计的高静压计量特性。非线性是通过一个二次无标准活塞计测量的。建立了二阶数学模型，插值精度达到0.07%，经标定试验验证。结果表明，锰电阻计具有很好的稳定性、重复性和再现性。

Establishment of math-model and analysis of interpolation accuracy on 1-GPa manganin resistance gauges

The high-static-pressure metrological characteristics of 1-GPa manganin resistance gauges are investigated. Nonlinearity is measured by means of a secondary standard-free piston gauge. A second-order mathematical-model is established, with an interpolation accuracy reaching 0.07%, as verified by calibration tests. The results obtained indicate that manganin resistance gauges exhibit very good stability, repeatability, and reproducibility.<>
