The effects of the waveform of pulse electric current and cooling conditions on the anodic oxidation process and the microstructure and properties of the hard anodic oxidation coating of motor piston were investigated using a specially designed apparatus.

This program was applied to calculate the temperature distribution of copper thin-slab continuous casting with different casting speeds and cooling conditions.

A multiphase model has been developed and applied to two dimension solidification processing of Al7 wet pct Si/SiC particles Fgm on different cooling conditions.

Through the experiments in which the grind-hardening of 65Mn steel has been carried out on a conventional surface grinder with alumina grinding wheel, the effect of the cooling conditions on the microstructures and properties in grind-hardened layer were investigated.

For the optimization of the mould cooling conditions,FEM code Marc has been adopted for the numerical simulation of the influence of the mould water flow rate,the outlet/inlet water temperature difference,the temperature of the inlet cooling water,and the wide of the water gap respectively.

In this paper,refrigerant is introduced into the reaction system,and optimum conditions are gained by orthogonal experiments as follows: The ratio of solvent(50% water and 50% alcohol) and thiourea is 1.

This paper applies the internal model control method to the refrigerant average temperature control problem of a nuclear reactor, using the open-loop impulse response series of the system as its non-parameter model.

By the solidification experiment of 30 %NH4ClH2O with adding refrigerant, the mechanism about the influences of refrigerant quantity and its adding ways on columnar to equiaxedcrystal transition (CET) has been studied.
