绝缘的

able to contain an electric field without conducting (= passing along) electricity

Dielectric grease can be applied to the exposed metal parts of virtually any electrical connection to seal and protect it. 介电润滑脂几乎可以涂在任何电线的裸露的金属部分上，起到密封和保护的作用。

The polymers are dielectric, meaning they are not conductors of electric currents but act as vehicles for the registration of electric fields. 这种聚合物是绝缘体，这意味着它不是电流的导体，而是电场的载体。

A dielectric barrier layer is formed to cover the metallic layer.
The gel is a dielectric lubricant that fights corrosion.
When a dielectric material is placed in an electric field, electric charges do not flow through the material as they do in an electrical conductor.

dielectric

noun [ C ] physics specialized uk/ˌdaɪ.ɪˈlek.trɪk/ us/ˌdaɪ.ɪˈlek.trɪk/

介电质，绝缘体

a substance or device that is able to contain an electric field without conducting (= passing along) electricity

Dielectrics are an essential constituent of capacitors. 介电质是电容器的重要组成部分。

Compare: insulator

A copper film is used but other films, such as dielectrics, may also be suitable.
The high voltage current flowing in the primary would have destroyed the capacitor dielectric.
Silicon's other role, when it is pure, is as a dielectric - a material that can be penetrated by an electric field, but not an electric current.
