WITH A MAXIMUM speed of 430kph (267mph), the Shanghai magnetic-levitation (or maglev) train is as much fairground rideas vital cog in the city’s transport system.

最高时速430公里（267英里）的上海磁悬浮不仅是一条展示线，也是该市交通系统重要的组成部分。

It also showed that the complex dielectric constant and complex permeability decrease as the measuring frequency increasing, and maximum dielectric loss was 0.30, but magnetic loss is small.

其介电常数、磁导率基本都随测试频率的增加而下降；介电损耗值最大可达到0.30，磁损耗值较小。

Close to the switching characteristics of the switch size is small, maximum detection distance. It can detect magnetic objects (usually permanent magnet), and then generate the output trigger switch.

接近开关的特点是以细小的开关体积达到最大的检测距离。它能检测磁性物体(一般是永久磁铁)，然后产生触发开关输出。

During solar maximum, the intense magnetic fields that reach above the Sun's surface become tangled, particularly near the sunspots.
