库仑定律

Following developments in electrical theories such as Coulomb's law , which showed that positive and negative charges attract, analogs in human life were developed, such as "opposites attract."

随着电学理论的发展，例如库仑定律的提出表明异种电荷相互吸引，类似的概念在人类生活中也被提出，例如"异性相吸"。

Coulomb's Electric Force Law states that opposite charges react to each other with a force that causes them to be attracted to each other.

Ether particles also are the media of electric field, between the opposite charge Ether particles in infinitesimal distance the rule of attracting is not meet the Coulomb's law, the strong interaction is the special situation of the electric field in the infinitesimal distance, it is not a new interaction.

以太是电场的介质，相反电荷在极小距离上产生的吸引作用并不满足库仑定律，所谓的强相互作用是电场极小距离时的特殊情况，并不是一种特殊的作用。

Equation (1) is Gauss theorem, it is can be derived from Coulomb's law, expressed the electric field diverges outward from the charge, equation (2) expression does not exist a separate poles.

In this thesis, we apply Coulomb's law and propose an external force to overcome the problem of traditional ACM that can not capture the cavities of an object. Assume that each node of a snake has its own electric charge, and the object boundary has opposite electric charge. Then object boundary will attract the nodes of the snake. This helps the contour easily to move to the object boundary.

本论文中，我们运用库仑定律的观念，提出了一个运用局部引力作为外力的方法，用以克服传统主动性轮廓模型在凹面处收敛不佳的缺点；假设物件边界带电，而主动性轮廓模型的结点带与物件边界相异之电荷，则物件边界会吸引著主动性轮廓模型各结点，使得模型曲线更容易靠近物件边界。

Simulation of micro-milling process is conducted using finite element method. During modeling, the Johnson-Cook's coupled thermal-mechanical model was employed as workpiece material model, the Johnson-Cook s shear failure principle was adopted as work piece failure principle, and the coupled thermal-mechanical hexahedron strain hybrid modules and adaptive grid were used to remesh the workpiece's elements. The friction between the tool and workpiece obeys the amended coulomb's law that combines with the sliding friction and the adhesive friction.
