The formulae in this paper are founded for axial piston pump whose rotor's structure is straight axis and auto-location type, but other type of pump can reference it.

文中算式以直轴自位式缸体结构的轴向柱塞泵为基本计算模型，但对于其他类型的轴向柱塞泵亦有很大参考应用价值。

Particularlya remounting of the models applied on the hinge axis and reference position ofthe lower jaw is indicated.

尤其强调的是，需要按照下颌的铰链轴位置和参考位重新上合架。

The expression of complex amplitude is given in reference plane vertical to the optical axis by far-field approximation when the line source and the principal axis are at any Angle.

在柱坐标下从微分波动方程出发，推导柱面光波的场分布，并利用远场近似条件导出当线光源与光轴成任意角度时，在垂直光轴方向的参考面上的复振幅表示。
