研究了有限厚度圆盘中高阶共转共振的行为。在m阶共振施加的扭矩是通过采用垂直平均的干扰功能，和这个扭矩的比率施加在一个冷的，二维盘被确定为所谓的扭矩截止功能。这个函数然后被用来计算贡献的共转力矩的偏心率变化的摄动的轨道假设在磁盘上运行。11篇参考文献。
The behavior of high-order corotation resonances in a disk of finite thickness is examined. The torque exerted at an mth-order resonance is determined by employing a vertically averaged disturbing function, and the ratio of this torque to that exerted on a cold, two-dimensional disk is identified as the so-called torque cutoff function. This function is then used to calculate contributions from the corotation torques to eccentricity variations of a perturber's orbit assumed orbiting in the disk. 11 references.
