Their flexing can be controlled independently by measuring the electrical resistance of the wires.

可以通过测量线路的电阻来独立控制它们的屈伸动作。

Its boiling point is -269 degrees centigrade. But if you cool things with liquid Helium, you get very strange properties, for example, some materials lose their electrical resistance.

它的沸点是-269摄氏度。 但是如果你用液态氦冷却东西，你会得到非常奇怪的特性， 例如，一些材料会失去电阻。
