Thereby, the single mode that the toy is moved along predetermined tracks can be changed, and the attraction force to the user can be increased.

由此改变玩具沿预定轨道运动的单一模式，增加对使用者的吸引力。

The revised schemes were designed basing on the original model features, and central planer coil structure was preferable by analyzing electromagnetic attraction force of movable contact.

基于已有模型的结构特点设计了电磁系统的改进方案，通过分析比较活动电极电磁吸力的分布规律，确定了中心平面线圈结构设计方案将更加合理。

So, when we get really close together, granted, there is a net positive negative charge with a Coulombic force of attraction.

当它们真正离得很近时，假设有一个带正负电的电荷,带有库仑引力。

And then the potential energy, the energy is stored here due to the coulombic force of attraction between the electron and the nucleus.

然后说势能,位能其实就是,由电子和原子核之间的库仑引力而形成的能量。

The reason is because the predominant force at this point is going to be the attraction that's being felt between the nuclei and the electrons in each of the atoms.

这是因为这时候最主要的力,是吸引力，它来自于,其中一个原子的电子与另外一个原子的原子核之间。

These proposals by the EU could force companies to move their headquarters elsewhere as the EU's attraction diminishes and London rental rates continue to aggressively climb.

CNN: Would EU bonus cap spark banker flight?

An uncanny force binds the speaker to the living, but the reality and attraction of the other world, death, strikes him so powerfully that it interrupts his speech on behalf of faith and life.
