A substance that does not conduct heat or electricity.
非导体
Example sentencesExamples
Most other minerals are non-conductors of electricity.
Substances such as hydrogen chloride or acetic acid are non-conductors in the pure state but give rise to ions and thus electrical conductivity when dissolved in water.
The term ‘fuel cell’ was coined by the English chemists Ludwig Mond and Carl Langer to describe their device, developed nearly 50 years later, which used a porous non-conductor to hold the electrolyte.
A non-conductor can be charged by induction by exposure to an electrostatic field that is present on a surface charged with static electricity.
They terminate at the surfaces of the conductors under induction, or at the particles of non-conductors, which, being electrified, are in that condition.

Example sentencesExamples
When both the first and the second two-terminal non-linear elements are in the non-conducting state, the voltage on the capacitor can be maintained.
When two non-conducting materials come into contact with each other, a chemical bond, known as adhesion, is formed between the two materials.
In fact, scientists have already been able to construct such wires, but they are relatively short and must be isolated from their neighbors by immersing them in a sea of other, non-conducting molecules.
