带电

We know that they carry the smallest possible charges of electricity, and we are learning much about the way they behave; but students are beginning to doubt that they have real substance, that they are anything one could hit with a lilliputian hammer.

我们知道它们都是带电体，而且我们已经学习过关于它们的运动行为方式的特点；但是学生们都开始怀疑这些质子和电子是否具有实体形态，怀疑小侏儒们的锤子是否能砸着它们。

It's dangerous to touch a live wire.

触摸带电的电线是最危险的。

If you touch that live wire you'll get a shock .

如果你接触那条带电的电线，你就会遭到电击。

If you touch a live wire you will get a shock .

如果你摸带电的电线，就会触电。

You will get a shock if you touch the live wire.

如果你碰这条带电的电线，你会触电。

That is a live wire.

那是一根带电的电线。

That wire is live.

那电线是带电的。

We can insulate a live wire with rubber.

我们可用橡胶使带电的电线绝缘。

When charged particles move in the magnetic field, they will experience an electromagnetic force called Lorentz force which is orthogonal to both the direction of velocity and magnetic field.

当带电的粒子在电磁场中运动时，会感受到电场与磁场的作用力，这个电磁力垂直於粒子的速度以及磁场方向。

It is found that the ground state corresponds to a high-resistance state, while the charge state corresponds to a low-resistance state.

研究发现，分子线基态对应较高的阻态，而带电态对应较低的阻态。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
