The paper brief express the basic physics performance and peculiar optics performance of nanometer SiO x,at the same time,particular discuss the scatter importance and essentiality of nanometer SiO x,as well as the scatter method in the architecture paint.

The system of estate ownership law,whose core is estate benefit,is something like a net composed of estate benefit, fundamental estate ownership, auxiliary estate ownership,compositive estate ownership and compositive ownership containing estate ownership,and a variety of compositive ownerships which exist in realistic life are its verges.

The results from tension test indicate that CG-FRP bars exhibit "yielding plateau" similar as steel bars,a comparison between theoretically and experimentally basic mechanical properties of CG-FRP bars was investigated with coincidence results,which provide an evidence for the application of CG-FRP bars in the civil engineering.

Some thematic engineering geological researches have been conducted in the north, middle and south section of the desert, through which the basic physical mechanics properties of the sand, such as compactibility, compressibility, permeability, frost and heave, .
