微重力下溶液法晶体生长模型中晶体生长界面稳定性的研究

摘要

The stability of the crystal growth face in a two-dimensional mathematical model of crystal growth from solution under microgravity is studied.The growth rate of a crystal is calculated for various tilt angles of the crystal growth face.It is known from the results of calculation that there exists possibly a stable growth face of the crystal.This face should be a suitably shaped curve with the upper end of the face tilting backwards.%研究在微重力条件下溶液法晶体生长的一个二维数学模型中晶体生长界面的稳定性问题。对晶体生长界面为不同倾斜角度的平面的情况作了数值计算，计算结果表明有可能存在一个稳定的晶体生长界面，它应该是一个在Y=λ这一端向后倾的适当形状的曲面。
