本文在文献[4]提出的振筒理论刻度方程的基础上,通过改善振筒性能和对振筒刻度性质的实验研究,在一定压力范围内做理论方程的幂级数展开,得到一种高精度刻度方程。它的残余非线性只达十万分之五到七。而且其倒数形式为线性函数,便于做回归分析。较其他各种刻度方法成本低、定标快、精度高并易于实现即时定标。
In this paper, based on the theoretical cylinder scale equation proposed in [4], by improving the performance of the cylinder and the experimental study on the graduation properties of the cylinder, the power series expansion of the theoretical equation is carried out within a certain pressure range to obtain a high Accuracy scale equation. Its residual nonlinearity is only five hundred thousandths to seven thousandths. And the reciprocal form of a linear function, easy to do regression analysis. Compared with other various scale methods, the method has the advantages of low cost, fast calibration, high precision and easy real-time calibration.
