the region is otherwise undistinguished at optical and radio wavelengths, but it does contain a number of oh and maser sources. 此区在光学和射电波段是不著名的，但却包含有许多OH和微波激射源。
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。
The spectral region in the red or near infrared will be emphasized, because this is a region of low loss for optical fibers and therefore of interest for optical communication systems . 着重研究光谱区域是红及近红外波段，因为这是光学纤维低损耗的区域，也就是对光通信系统有意义的区域。
