从化学工程的角度研究了GdAl_3(BO_3)_4熔剂体系中热力学控制和动力学控制在传质过程中的相互竞争。熔体生长体系中不同的传质控制机制导致了单晶不同的介观形貌。计算结果和实验结果都表明晶体生长过程中各向异性传质的热力学控制，导致了类似于Matryoshka的GdAl3(BO3)4单晶的细观形态演变。本工作可以加深我们对助熔剂生长系统中GdAl3(BO3)4单晶微观形貌演化的理解。
In the flux system of GdAl3(BO3)4, the compromise in competition between thermodynamic and kinetic control on the mass transfer has been studied from the viewpoint of chemical engineering. Different control mechanisms on the mass transfer in the melt growth system result in various mesoscale morphologies of a single crystal. Both the calculated and experimental results demonstrate thermodynamic control of the anisotropic mass transfer during crystal growth, leading to the mesoscale morphology evolution of the GdAl3(BO3)4 single crystal similar to the matryoshka. The present work can deepen our understanding of mesoscale morphology evolution of the GdAl3(BO3)4 single crystal in the flux growth system.
