非常规螺杆的轴向压力分布及压力降

Axial pressure distribution and pressure drop of unconventional screw stems.

在给定６点基本假设基础上，导出适用于各种非常规螺杆的轴向压力分布及压力降的计算公式。以等距变深、等深变距和锥形螺杆３种有代表性的非常规螺杆作为算例，在不同情况下计算了其轴向压力分布，给出了轴向压力分布曲线，并分析了计算结果。

After six basic hypotheses were given, the equations for calculating the axial pressure distribution and pressure drop of various kinds of unconventional screw stems were worked out. The axial pressure distributions of three typical unconventional screw stems were calculated, the axial pressure distribution curves were presented,and the results of calculation were analyzed.
