Titanium dioxide (TiO2) is one of popular semiconductor materials that usually used for photocatalytic application.
Many studies show that TiO2 has highly effective material for photocatalyst [1], solar cells [2,3], gas sensors [4], lithium batteries [5], self-cleaning materials [6] and so on.

(2)According to the processing information and practical situation in spot, the distribution plan of auxiliary tools and materials is formed, including the distribution amount and time of the auxiliary tools and materials to specified equipments
(3)The distribution plan is timely sent to tools and material warehouse in workshop, so that the tools and materials could be prepared in advance according the plan
Equipment consuming more materials within the same time is supplied with materials available with shorter waiting time.

Introduction Electromagnetic properties of material are determined by the values of permittivity and permeability.
But artificial materials with simultaneously negative relative permittivity and permeability have been realized at microwave frequencies in 2000.
Materials with unconventional values of permittivity and or permeability named metamaterials have been the object of intense research in the last few years.

Corrosion Condition The field study on the eroded concrete buildings in JRD and GID showed that white crystal materials appeared on the concrete structures surface and caused surface scaling and lower intensity.
At the second stage, the amount of expansion materials generate great expansion stress, destroy the pore structure and expand the small cracks.
The CM anti-Corrosion Composite Material was developed by Chinese Academy of Sciences，which is mainly used to improve the intensity of concrete.
