In current literatures methods of electric field calculations are only applicable to the case, where the potential differences between charged objects and the potential reference point are known.

在目前电场计算的文献中，限于计算电位参考点和各带电体间的电位差均为已知时的带电系统中的电场分布。

The potential energy of a unit charge at any point in an electric circuit measured with respect to a specified reference point in the circuit or to ground; voltage.

电势，电位相对于电路中某一特定参照点或地面的属于电路中任何一点的单位电荷势能；电压。

One, the status quo bias, has to do with our tendency to take our current situation as our reference point and to see any change as negative (or at least difficult) and with a high potential for regret.
