The conclusion shows that the nonlinear factor of electromagnetic material results in the density of stimulated current to be related to the position of the remote field.

结果表明：铁磁材料的非线性因素导致激励电流密度与二次穿透区的位置直接相关联。

And adopting the optimization design, high conductivity, the electromagnetic material production equipment in no-load loss low power output, more powerful, and stability, long service life.

并采用优化设计、高导电磁材料制作，致使设备在空载时损耗低、功率输出更强劲、稳定、寿命更长。

But when supermassive black holes at the center of a galaxy feed, the material falling into them heats up, giving off a bright glow across the electromagnetic spectrum.

然而，当星系中心质量超级大的黑洞“吞食”时，落入其中的物质便会升温，发出一道明亮的光，通过电磁波频谱可以显示出来。

Matter falling into them swirls around, and atoms rub together generating heat "like spinning a stick against another piece of wood to start a fire" and producing enough heat to make the material radiate across the electromagnetic spectrum.
