This conductivity creates a phenomenon we can see, when the excited charged particles escape.

这产生了我们能够看到的一种现象，此时激发了带电粒子逃逸。

If inundated by chloride ions, as a result of corrosion by salt water, their conductivity increases.

若因海水腐蚀而大量接触氯离子时，其导电性会增强。

The effects of high pressure can also work in reverse, causing some metals to lose conductivity or become insulators.

高压也能产生相反的效果，可能会使一些金属失去导电性或变成绝缘体。

First, they coated these with carbon nanotubes, to improve their conductivity.

首先，他们在这些木条子外面包上了碳纳米，以提高它们的导电性。

Wood also has low thermal conductivity, making it easier to heat and cool buildings with less energy waste.

木材还具有低导热性，使其更容易为建筑物供暖和制冷，减少能。

The smart bit is that the tubes' conductivity is affected by cracks in, or corrosion of, the painted surface.

之所以说它智能，是因为若涂层表面出现裂缝或被腐蚀，碳纳米管的导电性就会改变。

It works by measuring changes in the body such as blood pressure, pulse, respiration, and skin conductivity when a person is asked a series of questions.

当一个人被询问一连串问题时，这种仪器通过检测身体，诸如血压，脉搏，呼吸和皮肤的一些变化来测谎，。

Though silver is a good conductor, carbon is cheaper, and the nanotubes provide the extra electrical conductivity needed.

因此虽然银是良好导体，碳也很便宜，但是纳米管却可以额外提供必需的导电性。

The cables have extremely high conductivity, and they rival state-of-the-art polymers that we've developed for things like foldable cell phones and solar panels.

这些电缆具有极高的导电率，可与我们为可折叠手机和太阳能电池板等产品开发的最先进的聚合物相媲美。

Using a medical-imaging technique called electrical-impedance tomography, Dr Safi and his colleague David McGahon are devising software that can draw a conductivity map of an entire painted structure.

Mohamed Saafi博士及其同事David McGahon 正在利用一种叫电阻抗层析成像的医成像技术来设计一个能够为整座涂有这种涂料的建筑物绘制导电性能图的软件。

That does not affect their electrical conductivity, but nanoscale particles like this are known to scatter and obstruct the passage of heat through imperfectly understood quantum-mechanical processes.

它们的导电性不会因此受到影响，但是人们知道像这样的纳米级颗粒会分散开来并通过人们还尚未完全理解的量子力过程阻碍热量通道。

By changing the electrical charge of the gate, the conductivity of the semiconducting material can be manipulated, allowing current to flow or be stopped – like the water faucet analogy we discussed earlier.

通过改变" 门" 的电荷，我们可以控制半导体的导电性，允许电流流动或停止——就像前面提到的水龙头比喻。
