The four type of precipitated phase possess same body-centered cubic crystal structure and crystal constants, but different orientation relationship with α-Mg matrix, therefor, they will release different energy with their precipitating process, of course, they will absorb different energy with the solution process.

The structure tends close in this way and the stability of the system is improved considerably[4].
In such glass composition,the structure of SiO2 and [BO4], connected with SiO2,remain stable when they are etched by water[5].

The general features are: (i) The damage area- crater is not sharp as in the case of Fig. 1; (ii) appearance of a periodic structure on titanium, Fig. 2 (C2), was recorded; and (iii) plasma appeared in front of the target during irradiation.
A clearly pronounced crater was registered, but also cracks and grainy-structured layers inside the irradiated area, Fig. 3B3, instead of melted material.

The results indicate that the ultrasonic irradiation of a suspension of Fe(OH)3, Zn(OH)2 and Mn(OH)2 did not result in the formation of a spinel structure.
We believe that the formation of hematite in the early stage of the sonochemical treatment hinders direct formation of the spinel structure due to its high chemical stability and poor chemical reactivity.

Eu2O3 (99%) was obtained from changchun institute of appied chemistry.
Emission spectra of three complexes in the order of the fluorescence intensity is 3c>3b>3a, this phenomena can be explained that the ligands structure and conjugation of substituents affect luminescence efficiency of rare earth ions.
Incorporation of Eu(III) in the PNIPAM structure slightly increases the affinity of the polymer for water.

According to these performance characterizations, this modified asphalt by ANA should be designed for special pavement structure and tested by mixture experiments.
But the ductility of modified asphalt declines due to the higher rigidity of ANA, so this modified asphalt by ANA should be designed for special pavement structure.

Measurements of structures and properties.
Meanwhile, the breaking strength of the cotton thread remained basically unchanged when the periodate concentration was less than 2.0 mg/ml, whereas it decreased dramatically at the periodate concentration over 2.5 mg/ml due to breaking down the crystalline structure of the cotton cellulose.

Investigation of anticorrosive trivalent-chrome coatings on 6063 aluminum alloy Hui Cheng Yu, Fu Hou Lei，Guang Hui Deng and Xue Cai Tan School of Chemistry and Ecological Engineering, Guangxi University for Nationalities, Nanning 530006,Guangxi, China doyhc@126.com, leifuhou@163.com, dgh321@163.com, tanxc@yahoo.cn Keywords: Al alloy; Coating; Corrosion; Electrochemical techniques Abstract.
This is due to the difference of composition and structure of coating.
Considering the above results obtained, it is possible to conclude that the coatings with a more ordered compact structure, a more balanced morphology and an improved corrosion resistance surface was formed on the surface of Al 6063 alloy under the above optimum conditions.
