总体上，所有粒子都受到引力的作用，任何一枚粒子，它向空间发出的引力线并非仅仅着用于一个对象，引力子对外，仅形成引力，斥力子对外既形成斥力也形成引力，质子、中子是"微回旋星系"，它们以"星系"为单位在原子内部回旋，原子外层电子的数量要比现在认为的多上亿倍，原子结构是由这些成员力的关系和能量不灭规律决定的。

In the first part, first, the operational principle of Varivec Propeller is explained. Secondly, the mathematical model for predicting longitudinal and transverse movement hydrodynamic characteristics of Varivec Propeller under steady or unsteady condition are present, based on the general propeller lifting-surface theory, potential flow theory and Green theorem. Thirdly, theoretical calculation methods for predicting hydrodynamic characteristics when the influence of paraboloidal boss on the performance of Varivec Propeller is or isn't considered are present, based on The finite basic solution method, the unsteady vortex lattice method and Hess-Smith method Different rake angle is adopted according to different desire in practical application.
