4 lower power loss film material has high reflectivity and low light absorption, and low thermal conductivity, which largely prevent solar energy into the room.
更低的动力损耗膜材有较高的反射性及较低的光吸收低，而且热传导性较低，这极大程度上阻止太阳能进入室内。
The utility model has the characteristics of light weight, small dielectric gain loss, low dielectric thermal noise temperature, small input voltage standing wave ratio, etc.
本实用新型具有重量轻、介质增益损失小，介质热噪声温度低、输入电压驻波比小等特点。
The present invention has high thermal conductivity and low loss Angle tangent and may have relatively high machining accuracy.
本发明具有高热导性和低损耗角正切性能，并且可具有较高的加工精度。
