Simple harmonic curve is a perfect profile for cylinder inner wall. To decrease the leakage through the clearance of rotor and cylinder, a modified simple harmonic curve with sealed arc is developed.

简谐型线是旋叶式压缩机缸体比较理想的型线，为减小气缸与转子间的径向泄漏，在简谐型线的基础上开发出带过渡圆弧的简谐型线，称之为修正型线。

It should be noted that the rate of gas engine heat pump is limited regulation, and can not be any regulation, which is the work of the engine and compressor characteristics.

需要指出的是，燃气机热泵的速度调节是有限制的，并不能任意调节，这与发动机和压缩机的工作特性有关。
