先进材料疑固实验室 Application:Zone melting Laboratory of Advanced Materials Solidification Equation(3)shows that Cs*increases with x,so the starting end is purer than the finishing end. After many passes,Cs*~0 in a portion of the bar near the starting end. This means that the metal in this portion is significantly purified. vanced Mater形 上浒充通大学 SHANGHAI JIAO TONG UNIVERSITYApplication: Zone melting Equation (3) shows that CS* increases with x, so the starting end is purer than the finishing end.
