In order to study the thermal stresses at the mushy zone, a three dimensional rheological model [H]-[H\N]-[N\S] including elastic, visco-elastic and visco-plastic elements was established, its algorithm and codes for finite element method were also developed. A FDM/FEM integrated analysis system of thermal stresses was built based on the integration of this procedure with thermal analysis by finite difference method. A steel sample casting with a hot spot was simulated in order to validate this system, and the calculated and experimental results were in good agreement.

The calalytic perfomlances and surface surface of MgO prepared from different precursors were studied using cataytic test and pulse reaction techniques It was indicated that the MgO prepared from Ma(OH)24MgCO36H2O pretreated with distilled water exhibited the highest activity foe the oxidative coupling of methane. High lattice oxygen mobility and strong surface basicity may favor the OCM reaction.

The reduction of nitrite at Au or carbon electrode in-H_2SO_4 was found to follow achemical-electrochemical (CE) mechanism with a very thin (4×10(-8)cm) preceding reaction *** was proposed and experimentally verified that for such kind of electrode processes the totalreaction the could be effectively enhanced by using electrodes with increased true surface *** as porous electrodes. As a combination of porous electrode and microelectrode, the powdermicroclectrode shows excellent performance for nitrite detection.

A new kind of nonionic surfactant ionophore is introduced to facilitate metal ion transfer across a liquid/liquid interface. The transfer of Na+ facilitated by emulsifier OP across the water/nitrobenzene interface has been studied by semi-differential cyclic voltammetry, and a new method for the determination of emulsifier OP was established. The proposed method is simple, easy and effective.

The sputtering rates of alloys were investigated under constant Ar pressure and voltage supplied. The alloys studied in this work range from binary intermetallic alloys to ternary and quaternary alloys. It is revealed that the sputtering rates of alloy targets under steady states are q = 1/Sigma C-i/q(i)(0) where q is the sputtering rates of alloys, C-i the weight percentage of i-th component in the alloy, and q(i)(0) the sputtering rate of pure metal of i-th component.
