All uses such as refrigerant, insulator and deterge nt, etc.
Early electrical workers used it as a coating to insulate coils, and molded it into stand-alone insulators by pressing together layers of shellac-impreg-nated paper.
Insulator rupture has no effect on the tower component of the upper crossarm, but it has a significant influence on insulator tension of the upper crossarm.
As both insulator and energy storage media, de-ionized water combines the advantages of high relative permittivity(is about 80), self repairability, low cost and ease of handling.
And in an insulator, like rubber, electrons can't really flow at all.
And for retrofitting older buildings to be more energy effcient, wood is a good insulator.
And since asphalt is an insulator, it traps that heat over the course of the day.
All right, let's begin. Show of hands, who here is familiar with the concept of topological insulators?
好吧 开始上课 请举手告诉我 在座的哪位对拓扑绝缘体的概念比较熟悉？
The researchers think Dsup acts as a sort of chromatin insulator, shielding DNA from attack by hydroxyl radicals.
Most of the material is an insulator, but its surface can carry an electric current.
A topological insulator acts like both at the same time, which we used to think was impossible!
We do a fair amount in tiles and in insulators for electrical appliances. But kitchenware and tableware are our mainlines.

Nowadays, scientists are working to develop topological insulators, and some think they could be as important for future technologies as semiconductors are today.
Thouless and the final winner, Duncan Haldane, are both also using topology to pave the way for a new kind of material: topological insulators.
I've always found it interesting that snow, which is literally frozen water, is such a great insulator that structures made of it can keep you warm.
