| 摘 要： | 根据等离子体湍动波发电机方程，应用球坐标系统，得到了一组标量发电机方程。考虑各种不同的旋转情况，得到了不同的分析解，不论旋转角速是否均匀，对流是否存在，ｐ－ｗ发电机总能产生作用。较差自转的存在将增强发电机的作用，运用这种发电机模型能够解释所观测的无对流天体的磁场。

| Abstract: | Based on plasma turbulent wave dynamo equation (p-ω dynamo equation) and using spherical polar coordinates, a set of scalar dynamo equation is obtained. Considered various rotational situations, different analytical solutions are derived. No matter the rotation angular velocity is uniform or not, the convection is absence or presence, the p-ω dynamo is operative. The existence of differential rotation will enhance the action of p-ω dynamo. This dynamo may explain the observed magnetic field of CP stars. |
