	1	PHASE EXTENSION AND STRUCTURE ANALYSIS BY THE MAXIMUM ENTROPY METHOD显示文摘Excellent results are obtained in structure analysis with jew phases of structure factors by the maximum-entropy method (MEM) for CaGaN PbCO3 and ReBe22 single crystals. The computation time and memory space are minimized by symmetry operations so that structure analysis by the MEM can be carried out with a personal computer.	G.B.Hu and Q.B.Yang (Department of Physics, Xiangtan University, Xiangtan 411105, China)(Beijing Laboratory of Electron Microscopy, Center for Condensed Matter Physics, The Chinese Academy of Sciences, P. O. Box 2724, Beijing 100080, China)	1998	Acta Metallurgica Sinica(English Letters)1998，11，4：	1
	2	THERMAL STRUCTURAL DISORDER AND MELTING TRANSITION IN HIGH-ANGLE GRAIN-BOUNDARY: A MOLECULAR-DYNAMICS STUDY显示文摘A structural transition in the fcc ∑=5 (120)/[001] high-angle tilt grain-boundary(GB)is investigated by molecular-dynamics simulation. The calculations have been performed at various temperutures and the thermodynamic melting point Tm of the model system is determined by using a many-body potential fitted to copper. A thermal disorder transition in the GB region occurs well below the melting point. Our results indicate that such a transition is a continuous process and there is no evidence of premelting, which is entirely in accord with experiment results and theoretical prediction.Moreover we also observed that melting initiated at the interface and then propagated into the bulk quickly at or above Tm.
