树枝晶(dendritic crystal)是指一种能将其分枝成长过程中的某一阶段保留下来的树枝状晶体。其中有的是由于在其分枝成长过成中母液枯竭而直接残留下来的,有的是虽已无枝状形貌,但经过适当的溶液侵蚀而间接显现的。
此时,树枝晶已延生了半个电池。
That lets you know that the dendrites have grown halfway across the battery.
一般地,铸造组织为树枝晶组织,组织成分不均匀;
In general, dendrites occur in the microstructure of castings and the distribution of chemical elements is not homogeneous.
模拟结果表明熔体过冷度和树枝晶的计盒维数呈近似抛物线关系。
The results of simulations indicate that the relationship between melt undercooling and box counting dimension of dendrite is close to parabola.
