Dendrimers have been received extensive attention due to their designed structure, exterior functional groups and interior cavums [9].
Ag-G3.5-PAMAM may provide a basis for the development of novel nonenzymatic sensor, which may be used in detecting hydrogen peroxide in industrial water, environment analysis, food industry, clinical chemistry and so on.

Magnetorheological fluid is widely concerned by scientists from many fields such as physics, chemistry, mechanics, mathematics, materials science and mechanical engineering and has important research value[1-3].

It changes the surface of materials, internal organizational structure and stress state, improves strength of materials, fatigue resistance, wearresistant and stress corrosion resistant[1-2], thereby improves the fatigue life of metal materials , the security and the authenticity.

Artificial neural network The actual neural network exists in the brain is called the biological neural networks(BNN).On the other hand, artificial neural networks (ANN)is to imitate biological neural networks via electronic method, optical method or other biophysical chemistry method.
The advantages of BP model are: clear thinking, rigorous structure, stable working.

Data analysis In this study, with exploratory factor analysis to test the scale of construct validity, according to the theory of principal component analysis, utilize orthogonal rotations to decimation factor, and to determined the amount of each factors can explain the variation, to identify the underlying structure of the scale of good construct validity, and delete not suitable item regarding to factor loading, and to decide the number of subscale.

A Novel Strategy for the Synthesis of Azetidine Jian Suna, Shanshan Gongb, Qi Sunc,* Jiangxi Key Laboratory of Organic Chemistry, Jiangxi Science and Technology Normal University 605 Fenglin Avenue, Nanchang, Jiangxi 330013, PR China aemail:sunjian_jxstnu@163.com, bemail: gongshanshan33@gmail.com, cemail: sunqi96@tsinghua.org.cn Keywords: Azetidine; 3-Amino propanol; Diethyl phosphite; Phosphoramidate Abstract.
Though azetidine has the simplest structure, however, it is only commercially available in small quantity and high price.

At the same time as starting materials for their preparation, organic substances of different structure are often selected, the complexity of the synthesis of which largely determines the high cost of such products.
