In order to apply the concept of green chemistry into the actual production, we considered wood structure and chemical composition and utilized light absorption characteristic of wood to research the coloring method by UV light.
Considering the above factors, we researched the effect of UV-irradiation on surface color and chemical structures of mongolica followed by acid pretreatment.
The products were likely to contain unsaturated structures which changed the surface color of samples.

The meaning of modern science Physics has transformed the chemistry, is changing the life science, materials science, has been into electronics, finance, sociology.
With further analysis, we found that cross-structure of science in science and technology system has its location.
Therefore, we should based on the level and structure of complement, enrich and develop the sport form according to the Engels principles of scientific classification. 2. modern science has a highly differentiated and highly integrated features, the mutual penetration of various disciplines gives rise to new disciplines and integrated disciplines.
Physics has transformed the chemistry, is changing the life science, materials science, has been into electronics, finance, sociology, and social science issues (traffic flow, urban expansion, deserted systems, social network geometry, economic returns of scientific research, Financial physics, etc.) is closer to physics.

X-ray diffraction (XRD) found that all AZO samples have peaks of the ZnO hexagonal wurtzite structure.
Results and Discussion Effect of the ethanolamine family on crystal structure and optical properties.
This is to study the effect of autoclaved temperature on ZnO crystalline structure.
At 120℃, the ZnO particles showed individual nanoscale structures that are more preferential than of 100 and 140℃.
From these results, the different morphological structures may lead to different optical properties.

The results show that, La doping didn’t change the crystal structure, but the sample crystallinity was deteriorated.
Literatures suggest that, the lanthanum-doped affected directly on shift catalyst structure and performance [8-12].
The effect of La doping amount on composition, structure, activity and performance difference of the copper-manganese mixed oxides catalyst were studied.
