在考虑齿轮啮合刚度、啮合阻尼以及轴承刚度的情况下，使用集总参数法，建立了三轴式内齿行星齿轮减速器的弹性动力学模型，求解出不同内齿板结构下系统的固有频率及动力学响应。
On the inside of the door the figures 52 had been traced with a couple of strokes of a brush dipped in ink, and above the scantling the same hand had daubed the number 50, so that one hesitated.
在门的背面，有一个用毛笔蘸上墨水胡乱涂写的数字：52，横条上面，同一支毛笔却又涂上了另一数字：50，因而使人没法肯定。
