摘要：
The undercooled melt growth behaviors of benzophenone crystals were in situ observed to measure the growth rates of two selected crystal faces and aspect ratio of grown crystal. The results showed that the relations between growth rate, as well as aspect ratio, and the undercooling presented exponential profile. The expression of the aspect ratio with the undercooling was also deduced by using a two-dimensional crystal model. The agreement between theoretical prediction and experimental results implies that the undercooled melt growth kinetics of benzophenone crystals satisfied the two-dimensional nucleation mechanism.
