of anisotropy coefficients, the dendrites grow faster under the same condition. Key words: anisotropy; dendrite growth; crystal morphology; phase field method  .../liquid interface, and it is a key parameter affecting the evolution of crystal morphology. As long as free dendrites form stable morphology of tip, it must have anisotropy. At the same time, the growth......
