Only when it takes humidity ratio H/? as independent variable instead of absolute humidity H in researching and calculating the influence degree of the humidity on the discharge voltage, the emendation coefficients of relative air density and humidity can be independence, and can reflect the influence degree of atmospheric parameters on outer insulation discharge voltage actually.

当以比湿H／δ代替绝对湿度H为自变量研究和计算湿度对放电电压的影响程度时，相对空气密度校正系数和湿度校正系数才能相互独立，才能真实地反映大气参数对电气设备外绝缘放电电压的影响程度。

In other words, the method evaluates not only system voltage instability probability but also load curtailments to avoid system collapse that correspond to different voltage instability risk levels. The proposed method provides an effective tool to assess the voltage stability risk.

通过上述分析，不仅可以统计出系统的静态电压失稳概率，还可以得到为了避免电压失稳所对应的切负荷量期望值，由此为电压稳定风险评估提出了一条有效的途径。

The system voltage instability risk indices that are obtained using the risk assessment method include the voltage instability probability, expected load curtailment to avoid voltage instability, and the relationship between load curtailments and voltage instability probability.

该方法考虑发电机可用发电容量、电网结构及负荷的概率不确定性因素，利用蒙特卡洛模拟法抽样系统样本，并以所提电压稳定校正控制方法来判断样本的静态电压稳定性以及对样本进行电压稳定校正控制。

The higher surface energy of substrate results in higher effective viscosity and thicker ordered molecular film.

从侧面证明了有序液体模型的正确性，即薄膜润滑的成膜性能与近固体表面润滑剂分子的有序度密切相关；足够大的外电压使无序流体膜有序化，生成较高的有效粘度和较厚的油膜，并且二者随着外电压的增加，逐渐趋于稳定；外电场作用下，摩擦系数增大，切断电源后，摩擦系数减小，但不能恢复到未加电压前的摩擦系数值。

The withstand voltage is the level the equipment will withstand for a given length of time or number of applications without a disruptive discharge occurring, i.e.

耐受电压是对于给定时间长度和加压次数，设备能耐受而不损坏，即无绝缘损坏引起电压崩溃和电流流过的电压。

In peak time, the generator can adjust maximum of var even if the system voltage below wellformed voltage. In the low point, the bus voltage is high, and hold the admissible level.

在高峰负荷时段，即使系统电压低于合格水平，机组能按机组最大无功出力进行调节；在低谷时母线电压高又能深度进相运行；同时能保证厂用电电压水平在允许范围。

Ground parts: an overhead-type indicator by sampling ground capacitance transient current in the first half-wave and ground transient voltage in the first half-wave, to compare their phase, when the sampling ground capacitance transient current mutation and more than a certain value, and the instantaneous voltage and grounding The first-phase half-wave, while wire-to-ground voltage is reduced, then the judge circuit grounding occurred.

接地部分：架空型指示器通过采样接地瞬间的电容电流首半波与接地瞬间的电压首半波，比较其相位，当采样接地瞬间的电容电流突变且大于一定数值，并且与接地瞬间的电压首半波同相，同时导线对地电压降低，则判断线路发生接地。
