%X 本文主要研究了硼酸介稳区和结晶3D成核理论模型，为考察不同杂质离子对硼酸介稳区的影响，实验选取了2种典型杂质离子Na+、Cl−，每种离子选取3个浓度(200 ppm、600 ppm和1000 ppm)。结果表明随着杂质离子含量的增加，经修正后硼酸的成核级数也逐渐增大。Na+和Cl−的对成核级数的影响大致相同。结晶3D成核理论模型的研究表明，在纯硼酸溶液中，随着饱和温度的提升，其界面能γ逐渐降低，而动力学因子A则呈现相反的变化趋势。而对于同一温度下的饱和硼酸溶液，杂质离子的加入会使得界面能γ逐渐增大，离子浓度越大，界面能的增幅越大。
In this paper, the metastable zone of boric acid and the 3D nucleation theoretical model were investigated. To examine the effects of different impurity ions on the metastable zone of boric acid, two typical impurity ions (Na+ and Cl−) were selected for experimentation, each at three concentrations (200 ppm, 600 ppm, and 1000 ppm). The results demonstrate that as the impurity ion concentration increases, the corrected nucleation order of boric acid gradually rises. The influence of Na+ and Cl− on the nucleation order was found to be broadly similar. The study of the 3D nucleation theory model of crystallization shows that in pure boric acid solution, as the saturation temperature increases, the interfacial energy γ gradually decreases, while the kinetic factor A shows the opposite trend of change. For saturated boric acid solutions at the same temperature, the addition of impurity ions leads to a gradual increase in interfacial energy (γ), with higher ion concentrations resulting in greater increments of interfacial energy.
