The electric potential and the field of point charge are resolved with a special function.

利用特殊函数求解电势、电场，计算了点电荷与磁偶极子相互作用的电磁角动量。

In order to optimize the computation method, the charge simulation method has been developed combined with the equivalent line and point charge.

为了优化计算，提出了线电荷与点电荷相结合的等效电荷法。

Then by the principle of superposition and solving two sets of algebraic equations, the interaction between the point force and the point charge was uncoupled.

利用线性叠加原理，通过求解两组代数方程组，从而分离出点力与点电荷的耦合作用。

And the point that I also want to make is the way that they differ, z effective actually differs from the total charge in the nucleus due to an idea called shielding.

我也想指出的一点是它们不同的方式,有效的z事实上不同于原子核的，总电荷量,因为屏蔽效应。

It's also looking to add all Scottish PiP-funded public charging points to a National Charge Point Registry, which is available online.

Point One can charge 10% to 15% less than existing long-distance companies to handle such traffic and still earn gross margins above the 20% to 30% generated by the big long-distance firms.

These address some major concerns with the first Supercharger stations, particularly the long wait times for an available charge point and also some disappointment around the amount of additional range one could obtain in a reasonable stop time.
