势能

Based on the theory of eletrodynamics and other related subjects, an energy model was established for studying the mechanism of projected transfer mode by introducing "Surface Evolver" as a means of FEM analysis, by commutating and presenting the energy (eletromagnetic, gravity and so on) in the droplet transfer system.

摘 要：为研究MIG/MAG焊的射滴过渡机制，引入Surface Evolver软件作为有限元分析手段，根据电动力学和其它相关学科的基础理论，通过对射滴过渡系统中电磁能和重力势能的数学变换和描述，建立了适合于该软件运行条件的射滴过渡能量模型。

如果一个物体在重力场中从A点下降到了B点，那么重力就要对这个物体做功，重力势能就会相应的减少，反之亦然。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
