1·The results show that the dendrite crystal area of alloy is diminished and then become equiaxed structures after lithium is added;
结果表明：锂能消除合金凝固态的柱状晶区并使之转变为等轴晶区；
2·The whole process of the dendrite growth in PGO melt crystal growth was visualized in the in situ observation system.
本文介绍了用实时观察方法研究水溶液中晶体生长长机制的实验。
