红外反射率 meaning in English

infrared reflectivity

The lush vegetation shows large infrared reflectance, which the surrounding geological areas are only as bright as that shown on the green spectral record .
茂盛的植被具有很高的红外反射率，而周围的地质区域却和绿波段中一样亮。

铝及铝合金阳极氧化镀层试验方法.第14部分:红外反射率测定
Both the dielectric layer and metal film were internally deposited on the fiber . it is found that ag is able to engender the highest ir reflectivity among the metal materials , so ag is ascertained as the metal layer material of the hollow waveguide , cop was used in this work as the dielectric material . based on countless calculations , optimum thickness for the deposited films were obtained , namely , 0 . 2 / / m for ag layer and 1 . 4 fan for the cop layer
实验用来制备空芯光纤的基管材料为石英基管；内径为1mm ；通过理论推导与分析发现：相对于其它的金属材料而言，金属银的红外反射率最高，因此金属银最适合用做制备空芯光纤的金属膜层的材料；通过比较几种聚合物的性质确定选择环烯聚合物cop为电介质层材料；通过理论推导与计算确定了金属银膜与电介质膜的最佳理论厚度，即银膜为0 . 2 m ， cop膜的厚度为1 . 4 m 。
