电压，始终是衡量两者间电势差的物理量。
Voltage is always the measure of a potential difference between two bodies.
当温度趋向0K时，正向结电压趋向内建电势差。
The positive junction volt tends towards the build-up potential while temperature goes to 0K.
给出了一种利用霍尔效应测量螺线管磁场的新方法：用数字电压表取代电位差计等诸多仪器测量霍尔电势差，进而计算出通电长直螺线管内轴向磁场的分布。
Digital voltmeters, instead of voltage meters and other instruments, are used to measure Hull voltage and then to calculate the axial magnetic induction distribution in charged straight spiral tubes.
