The Gas Sensitvity Character of WO3 Nanosized Material HUANG Shi-zhen1,a , LIN Wei 1,b ，CHEN Wen-zhe1,c 1 Department of Electronic science Applied Physics, Fuzhou University,Fuzhou 350002,China a email: hs501@fzu.edu.cn b email: mqks@fzu.edu.cn cemail: cwz@fzu.edu.cn Key words: Nanosized material; WO3; NO2 Abstract By thermal decomposition, WO3 nanosized material was prepared as sensitive material and doped SiO2 nanosized material has been prepared using Sol-Gel process.
WO3 is a material developed in recent years.
Figure 1(a) and figure 1(b) are SEM pictures of microstructure of materials doped with SiO2 and pure WO3 respectively.
In the sinter temperature of 500-600℃，surface activity of grains of the sensing material is strong and BET of the material is large, result in high sensitivity to NO2 of the material.

The aim of the present study is to clarify the actual conditions of indoor thermal environment with building materials, which built after 1980 years in urban areas of Zhejiang Province.
The results show that the wall materials of the most residential buildings are clay solid bricks, the most windows type is aluminum alloy, and the most buildings are uninsulated.
Fig.5 shows the wall materials of the investigated residential buildings.
The wall materials of the most buildings were clay solid bricks, and the ratio of perforated brick to all is about 20%.

Intelligent Matching of Cutting Tools with Workpiece Materials J.
Those cutting tools, which materials have greatly chemical affinity with workpiece materials, are scarely selected.
Those ceramic tools which materials contain aluminum and Ti elements, i.e.
After matching in material performance between cutting tool and workpiece materials, geometry angle needs to be considered.

The reversible changes are material expansion and plasticization, which could be clear up after dry the materials.
Matrix plays an important role in composite materials.
