损耗

The permittivities of the composites decreased with increase of frequency or ferromagnetic YIG content.

复合材料的介电损耗峰随频率的增加向温度高的方向移动。

Busbar in the actual operation of the current great up hundreds of thousands of amperes and voltage is very small, and because of wear and tear resistance fever, If not timely heat, the temperature would increase bus may exceed the allowable temperature, which can affect their work performance, even burn.

母线在实际运行中通过的电流很大可达几十万安培而电压很小，且由于电阻损耗而发热，如不能及时散热，母线温度将升高，可能超过允许温度，从而影响其工作性能，甚至可能烧坏。

The distributing function of geodesic lens mode field w as established in this paper.
