Definition of dielectric in English: dielectricadjective ˌdʌɪɪˈlɛktrɪkˌdaɪəˈlɛktrɪk Physics Having the property of transmitting electric force without conduction; insulating. 电介质的；绝缘的 Example sentencesExamples - An electrically polarizable object will be trapped in a region of a focused electric field, provided there is sufficient dielectric response to overcome thermal energy and the electrophoretic force.
- The accumulation of excessive electric charge in dielectric insulation is extremely rare, but when it does occur, it is often catastrophic.
- The conductance caused by dielectric breakdown of membranes is proportional to the amplitude and duration of the electric field.
- Under normal circumstances, very few high-energy electrons lodge in the dielectric materials, and most naturally leak away over time.
- The basic assumption is that electronic dielectric response is everywhere uniform.
noun ˌdʌɪɪˈlɛktrɪkˌdaɪəˈlɛktrɪk Physics A medium or substance with a dielectric property; an insulator. 电介质；绝缘体 Example sentencesExamples - At that size, it expects to make use of new materials and high-k dielectrics.
- This differs from the usual approach, which embeds the side chain directly within the protein dielectric.
- The dielectric can be air, paper, plastic or anything else that does not conduct electricity and keeps the plates from touching each other.
- In many photonic structures composed of two or more dielectrics, the absolute value of the refractive index contrast is critical to performance.
- But low-k dielectrics improve the insulation between the circuits, thus allowing efficient transistor switching without the need for excessive power, and consequently without the extra heat.
Derivativesadverb Physics It is a dielectrically isolated, high-speed, complementary bipolar IC process that uses a technology called deep trench on bonded wafer, and enables complete dielectric isolation. Example sentencesExamples - The magnitude of the first effect depends on the (dielectrically weighted) relative depth of groups A and B in the membrane.
- According to another embodiment, the second cover is dielectrically isolated from a current collector.
- In addition, for systems composed of dielectrically significantly dissimilar regions, ionic energetics is sensitive to the long-range artifacts imposed by periodic boundary conditions.
- The dielectrically weighted distance between them had to be > 0.86.
OriginMid 19th century: from di-3 + electric, literally 'across which electricity is transmitted (without conduction)'.
