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。

On our rolling Wall Street contract, it's a 3 point charge - and that's nothing in the current market, "argues Morris."

莫里斯辩称：“我们的滚动华尔街合约收费是3个点——这在目前市场上算不上什么。”

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。

The confinement_potential of point charge in electrostatic field requests anti_dielectric or mirror line of arranged free point charge out of confined region.

证明了静电场中点电荷的禁闭条件是禁闭区外部为抗电介质，或者在禁闭区外排布镜像点自由电荷系列线。

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。
