For these reasons, the breaker-and-a-half switchyard scheme is generally preferred for transmission switchyards and a line tap (particularly for high-voltage and extra-high-voltage lines) would not be considered acceptable.

基于这些原因，断路器和一个半开关计划是普遍的首选传输switchyards和线塔（特别是高电压和特高电压线）将不会被视为是可以接受的。

Based on the rigorous analysis of the kinetic process of both primary and secondary electrons, the related surface charges were analyzed, and the energy gain of emitted electrons was proportional to the square of the ratio between the tangential and normal component of electric field.

在前人工作的基础上，进一步严格推导了场致一次发射电子和二次电子的运动方程，分析了电子发射引起的绝缘材料表面带电，表明电子发射后的能量增益正比于场强的切向与法向分量比值 F /// F ^的二次方；同时考虑了在电子发射和运动过程中电荷镜像力的作用，并探讨了交流电压下表面带电的情形，认为当考虑电荷镜像力的作用时，电子的能量增益可能变小，而工频交流电压下电场交变对电子运动的影响可以忽略。

The telegraph equation is first deduced when people studied the changing law between the voltage and current in the telegraph wire.

电报方程最初是在研究电报线上电压电流的变化规律时推导出来的，它表征均匀传输线上电压电流的关系，故该方程也称为传输线方程。

Local control of voltage by means of autotransformers will lead to increase of current and this in tern will increase voltage drops in lines.

当地的用于电压控制的自感变压器也将从而产生更高的电流，这样使得输电线上的电压降增加。

AC and DC voltage measurement to the instrument automatically selects the range and test the voltage probes match.

AC和DC电压测量使仪器自动选择量程来和测试探针的电压相匹配。

Electrostatic relays can be not compatible with the normal voltage (5V) because it needs high driving voltage. Thermomagnetic ones have the low response speed and are affected by the ambient temperature.

静电型由于需要较高的驱动电压，不易与标准电压源（5V）相兼容；热磁型响应速度低，受环境影响较大；微机械电磁继电器在结构原理上与传统机械继电器相似，更接近于实际应用。

The minimum of the surface potential is used to deduce the threshold voltage model.

同时利用阈值电压的定义得到了阈值电压的模型。

The output voltage and the detector threshold voltage can be set individually for each IC by laser trimming.

Based on physical characteristics, existing stochastic estimation methods of equipment sensitivity to voltage sag use subjective probability models to express the probability distribution of voltage tolerance curve of equipment in the uncertain region. But the parameter estimation needs vast sample data. These methods may result in man-made errors.

现有负荷敏感度随机估计法以电压暂降的物理特征为基础，用主观概率模型描述负荷电压耐受曲线(voltage tolerance curve，VTC)的随机分布规律，所需样本量大，在实际中难以实现且可能引入主观误差。
