| 摘 要： | 通过光学显微镜观察NaCl稀溶液在玻璃基底上快速蒸发结晶形成了完整的立方晶体、DLA凝聚体和形状复杂的凹凸状结晶3种形貌.对复杂的凹凸状结晶进行分析,认为不完整的NaCl小晶粒构成了一个个微小的生成元,以随机Koch曲线的生长方式自组织地顺次相互连接起来,指出此类结晶符合随机Koch曲线,是远离平衡态下的自组织现象.通过改变观测尺度求维数的方法,得到分形维数是1.15±0.06,与Koch曲线相近. |

| Abstract: | The crystallization morphology of NaCl dilute solution which evaporated rapidly on glass substrate is observed by optical microscope.Three types of morphologies including complete cubic crystal,DLA aggregates and concave-convex crystallization in complex shapes are found.The analysis of the concave-convex crystallization in complex shapes show that self-organized tiny generators formed by incomplete sodium chloride small crystals connected successively in a growth path of random Koch curve.And it's pointed ... |
