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。
The frequency changes of the excitatory neurons in Zusanli and Neiguan groups were also obvious higher than those in Pianli and Heyang groups(P<0.01).
针刺内关、足三里穴组兴奋性神经元频率变化率亦显著高于针刺偏历、合阳穴组（P〈0.01）。
Secondly, the paper is verified theoretically that the natural frequency changes of structure contain the information such as location and degree of the damage.
其次，论文通过理论分析，得出了工程结构损伤前后的固有频率的变化规律，并且该变化规律包含了结构损伤位置的信息和损伤程度的信息。
