reflectivity

反射率英释中释na measure of the ability of a surface to reflect radiation, equal to the reflectance of a layer of material sufficiently thick for the reflectance not to depend on the thickness

1 With these layers downloaded, you can combine them with the base reflectivity image to produce a more easily readable image map..下载了这些图层之后，您可以把它们与基本反射率图像结合起来生成更易于阅读的图像地图。

2 Using a model that simulates how light, water, and air interact, Seitz found that microbubbles could double the reflectivity of water at a concentration of only one part per million by volume..塞茨利用一个模型模仿了光、水和空气是如何产生相互作用的，他发现：按体积计算，密度仅为百万分之一时，微型气泡可以使水的反射率加倍。

3 Do not include the radar base reflectivity image as it can make precise area location more difficult..请勿包括雷达基本反射率图像，因为它可能会使精确定位地区变得更困难。
