aIn addition, after CNS injury CSPGs are one of the main neurite growth-inhibitory molecules present in the glial scar and play a crucial part in the failure of axon regeneration. 另外,在CNS伤害CSPGs是其中一个主要neurite成长禁止分子当前在glial伤痕并且起关键的作用在轴突再生之后的失败。[translate]...
aInsulator (electrical). A nonmetallic material that has a filled valence band at 0 K and a relatively wide energyband gap.Consequently,the room-temperature electrical conductivityisverylow,lessthan about 10?10(?-m)?1. 正在翻译,请等待... [translate] ...
A vacuum tube is an electronic device that uses a vacuum as an insulator and to shield against electric currents. It works by creating a vacuum inside the tube, which means there is no air or other material inside that could conduct electricity. Vacuum tubes are also known as valves in som...

Step by step video & image solution for Solid A is a very hard electrical insulator in solid as well as in molten state and melts at extremely high temperature. What type of solid is it? by Chemistry experts to help you in doubts & scoring excellent marks in Class 12 exams. ...
What Is a Semiconductor? A semiconductor is a material product with some of the properties of both insulators and conductors (hencesemi,meaning half or partial, conductor). Semiconductors are usually comprised of silicon, since this conducts electricity more than an insulator, such as glass, but ...
Electricity is all around us--powering technology like our cell phones, computers, lights, soldering irons, and air conditioners. It's tough to escape it in our modern world. Even when you try to escape electricity, it's still at work throughout nature, from the lightning in a thunderstorm...
Breakdown voltage is defined as a minimum voltage level at which the insulator starts behaving as a conductor and a large number of current passes through an insulator. The electrical properties of a diode lie between insulator and conductor because diodes are made up of semiconductor materials like...
