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。

If Q2 were negative, this might be representation of E2, pointing to negative charge, and if this one (Q3) were negative, then I would have here the contribution E3, and so on, and now we use the superposition principle as we did last time which Coulomb's law, that the net electric field at point p is a vector, is E1 influence of charge Q1, plus the vector E2, plus E3 and so on.
如果Q2是负的,这就是Q2的表示法,方向指向负电荷。如果这个是带负电,它将贡献电场E3,等等。现在我们使用叠加原理,就像我们上次在库伦定律中使用到的。

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.
采用有限元方法对微细铣削过程进行模拟,采用Johnson-Cook热力耦合模型作为工件材料模型,采用Johnson-Cook的剪切失效法则作为工件材料的失效准则,采用热力耦合平面应变杂交单元并使用自适应网格技术进行网格划分,刀具与工件间的摩擦采用滑动摩擦区和粘着摩擦区相结合的修正库仑定律。

Physics concepts, theorems as well as principles are primary content of physics learning, those knowledge take on the forms by proposition . In chapter 3, the study revealed that physics proposition are mainly obtained by reasoning (inductive reasoning such as tallying method, differentiation method and covariant method, deductive reasoning such as negative expression of hypothetical inference, affirmative expression of hypothetical inference ).Then by the means of experiment, the different condition needed when applying those reasoning was explored.
由于定义性概念、定理和定律等命题知识是物理教学的主要内容,所以在第三章中首先通过研究,表明物理命题主要是运用推理策略获得的(归纳推理策略中的求同策略、差异策略和共变策略,演绎推理策略);然后通过实验等方法研究使用策略需要的条件;最后依据前面的研究提出适合物理命题学习的任务分析方法。
