不平衡

As the core component,rotor system may run abnormally,have the failures of unbalance,bearing damage and incorret alignment.

作为它核心部件，转子系统运行过程中可能出现、对中、轴承损坏等故障。

Here, free electrons rub off the con ductor and create a charge imbalance that causes the current flow.

这时，摩擦引起自由电子脱离导体，产生电荷，从而产生电流。

So long as their balance remains undisturbed, the oxygenated and hydrogen sulfide–saturated waters stay separated, and their interface, known as the chemocline, is stable.

直到达成、相干扰，充氧水与饱和硫化水彼此分隔，而且两者间界面「化变层」也是稳定。

In the presence of impurities or in a nonstoichiometric solid, free electrons or electron holes are produced as a result of “charge compensation” to neutralize the effect of charged ionic defects 。

在杂质存在情况下，或在非化学计量比固体中，为了中和带电离子缺陷所引起电荷，便会产生自由电子或电子空穴。
