LCA is not only applied to technological sciences and natural science, but also is applied extensively to social science, economic science, management science and international relationship etc.
For instance, a series of equipment activity, such as manufacturing of the tank, overhauling repairmen of naval vessel, maintenance of fighter plane, accession of fuel of rocket guided missile, warehousing and transportation of Military Materials etc, may all cause polluting to the surrounding environment seriously.

Highly porous materials can be made from different types of materials, such as metals, polymers or ceramics.
The properties of porous materials depend on their specific use in practice.
It is effort to achieve this trend in the prepared porous materials.
