用此非线性方法对仪器刻度，使得国产连斜-井径并测仪的井径线性不好的问题得到了明显改善。

This nonlinear calibration method is used to calibrate the caliper tool, which obviously improves the measuring accuracy of the caliper tool made in China.

并认为流量与转子所处的高度非线性关系；流量的刻度标定也是非简单线性变化。

The results show that the relationship between the flow and the height of the rotor is not linear, and that the flow scale on the meter is uneven.
