permeability

The most interesting dimension of this is what Google Search Appliance says about the increasing permeability of a company and the outside world.

其中，最有趣的一点是谷歌搜索设备所反映的“公司和外部世界日益增加的渗透性”。

The idea behind enhanced, or engineered, geothermal systems is to inject water underground to enhance the permeability of rock, allowing for the release and capture of more heat.

增强型的或是工程型的地热系统将水注入到地下，使岩石的渗透性提高，这样便可以吸收或释放更多热量。
