fixed power

Common DC bus is mainly composed of rectification and inverter unit, with which three-phase alternating current becoming into fixed power direct current, then direct current is again converted into frequency and voltage adjustable alternating current by inverter to control motor speed.

公共直流母线技术主要由整流单元和逆变单元组成，三相交流电经过整流单元以后，变成一定功率的直流电，再经过逆变单元变成频率和电压可调的交流电源，用来控制交流电机的速度。

Moreover, for the fixed power setting of PZT transducer, the temperature change can lead to difference in actual power and impedance of PZT transducer.

而且，对于恒定额定功率设置的PZT换能器系统，温度的改变导致PZT换能器实际加载的功率及阻抗的改变。

officials are caught between two policies -- fixed power tariffs, and coal prices freed to float several years ago.

现在，中国的政策决策者们被捆绑于两个政策之间——电力价格固定，而数年前开始实行的煤价自由浮动。
