论文摘要
对于具有生长缺陷的$^4 $ HE水晶，观察到了“爆发样的增长”制度。该观察结果证实了导致晶体方面向高温和低温下异常快速生长状态过渡的相同物理机制的假设。发现动力学生长系数的松弛过程类似于快速生长阶段结束时晶体的弹性模块的松弛。动力学生长系数在快速和缓慢生长的阶段确定。发现从快速到缓慢的晶体面生长动力学的跨界跨界很刺耳
The "burst-like growth" regime is observed for the $^4$He crystals with the growth defects. The observation has confirmed the hypothesis for the same physical mechanisms responsible for the transition of the crystalline facets to the state of abnormally fast growth at high and low temperatures. The relaxation process of the kinetic growth coefficient is found to be similar to the relaxation of the elastic modules of the crystal at the end of the fast growth stage. The kinetic growth coefficients are determined at the stages of fast and slow growth. The crossover from the fast to slow kinetics of crystal facet growth is found to be drastic
