The structure and process of BIOSTYR~,a new generation of biological aerated filter with light filtering material are analyzed.

A new biological filter called biostyr using biostyrene as media to purify raw water was compared with the widely studied bio-ceramic filter.

Researches on the floating media filter;

Through the GRC density,mechanical properties testing include tensile strength and flexural strength test,and thermal conductivity analysis,it can be found out with appropriate alkali resistant glass fiber ratio,water ratio,water-cement ratio,light material ratio,the material can achieve the best performance,such as density of 0.

Natural environmental corrosion protection technology database for light materials was designed and established making use of material corrosion data and environmental corrosion data of natural environmental test network,under the Windows operating system,and adopting SQL database management system.

As a kind of geotechnical material, light material is made of artificial materials, the primary character of which is that it is lighter than common soil while the intensity and the deformation feature may be equal to or even be better than good soil.

In the design for the reinforment,lightweight materials are used to reduce the weight of the building itself,and some measures are taken to decrease the measure length of the ground column so that the building can be more earthquake resistant.

Lightweight material s application actuality using to automobile is instroduced, and expatiate that using lightweight material is important path of automobile energy conservation.

The mathematical model of light fuel oil production was then constructed.
