BCF theory were verified by lots of experiments of the crystal grown from vapour phase,but it has not yet proved quantitatively to the growth in aqueous solutions.In this paper,a method is introduced to study the mechanism of crystal growth by in situ obervation on the step movements of the crystal grown from aqueous solutions.The results of the experiments have showed that the distance of a step train is considerably larger than the step height. Among various methods, the phase contrast microscoped is most effective to observe the microstructure of the crystal face in aqueous solution. Combining a microscope with the TV camera and video recorder system , make it convenient to study the process of crystal growth in aqueous solution.
