查询词典 crystal diffraction

It was indicated that the effect of crystal orientation on interfacial stability is because of the different atomic bond number formed in the solidification of liquid atoms on different crystal planes, which affects the decrease of system energy, and affects the effective jump frequency of liquid atom migration to solid interface and solid atom migration to liquid, and finally affects the solute distribution in the front of liquid-solid interface and composition undercooling.

研究表明，晶体取向对凝固界面稳定性的影响是由于液相原子在不同晶面结晶面上沉积时形成的原子键不同，影响了系统自由能的降低，影响了液相原子迁移至固相界面上的有效跳动频率和固相原子迁移至液相中的有效跳动频率，影响了液固相界面前沿的溶质分布和成分过冷所致。
