不平衡

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

作为它的核心部件，转子系统运行过程中可能出现不平衡、不对中、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，摩擦引起自由子脱离导体，荷不平衡，从而流。

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.

直到达成平衡、不相干扰，充氧的海水与饱和硫化氢的海水隔，而且两者间的界面「化变层」也是稳定的。

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 。

在杂质存在的情况下，或在非化学计量比的固体中，为了中和带离子缺陷所引起的荷不平衡，便会自由子或子空穴。
