电磁共振

在提高传统压缩机COP的基础上，许多公司提出使用线性压缩机，通过线性电动机以电磁共振方式驱动，而不由旋转电动机通过机械连接方式驱动压缩机。

On the base of improving COP of conventional compressors , linear compressor has a simple structure with no crank mechanism , which greatly makes friction and noise less and less .

另外一家名叫WiTricity的公司还使用了电磁共振耦合技术，这也是一种完全具有可行性的技术，但它只在给距离很近的大型物体充电时才有效。

Then with magnetic resonance coupling , which a company called WiTricity is using , it 's a totally viable technology but it 's only effective in charging really large objects over really short distances .
