拉伐尔喷管曲线方程的建立及其数控加工

THE ERECTION OF THE CURVE EQUATION OF THE LAVAL NOZZLE AND ITS NUMERICAL-CONTROLLED PROCESSING

建立了拉伐尔喷管内部形状曲线方程，开发了集计算机辅助设计与制造于一体的应用软件，为提高喷射式真空泵工作性能提供了工具与指导．

n this paper, the curve equation of the laval nozzle′s inner shape is erected, and the application software which contains the laval nozzle′s CAD and CAM is designed. This will be of great importance for improving the working property of the stream jet vaccum pump.
