A stationary growth of the dendritic tip having the tip shape of an elliptical paraboloid in a binary liquid is considered. A method for constructing a selection criterion that allows one to obtain the growth rate and two radii of the dendritic tip as functions of undercooling is proposed. Selection constants are found theoretically for the n-fold crystalline symmetry. The theory is in good agreement with experimental data obtained on water and water solution previously described in literature.

稳定树突生长理论中的选择常数

考虑在二元液体中具有椭圆抛物面的尖端形状的树枝状尖端的稳定生长。提出了一种构建选择标准的方法，该选择标准允许过冷的函数获得树枝状尖端的生长速率和两个半径。理论上发现选择常数为n-倍晶体对称性。该理论与先前在文献中描述的关于水和水溶液的实验数据非常吻合。
