This doesn't sound like dynamic frequency changes yet and in fact it isn't.

这听起来还不是动态频率改变，实际上它也不是。

Then, a kind of optimization design method of the cooling parameters based on the minimum frequency changes of the cavities is proposed.

而后，提出了一种基于最小频率离散度的冷却参数的优化设计方法。

After these, the structural natural frequency changes a little, but the grinder bed mass reduces greatly, thus the obvious result is achieved.

优化后，结构固有频率及刚度变化不大，而床身质量却大大下降，取得明显效果。
