| Abstract: | After deep research of the physics meanings of the parameter Bi(i=1,2,3,4) in the temp field equation T = B1eB2X+B3Z of S - L interface during directional solidification , the author inducts the control condition and adopts the advanced M - L method to resolve the initial value problem which is confronted in the application of the temp field equation of S - L interface . By using the strong numerical calculation and visualiz ation function of MATLAB to write the programs, the experimental data can be efficiently treated, which results in the solidification parameters Tc , V, G, R . |
