不知您注意过没有,冬天,当气温在零摄氏度以下、雪花形成的时候,微细的冰晶会渐渐围绕着凝结成冰核,而雪花亦随之诞生。这个过程被称为“结晶”。在结晶过程中,水分子会以它们的基本排列方式从液态变成固态。由于冰晶的基本模式是六角棱体,大部分冰晶的雏形都是六角形的。当更多的水分子与冰晶结合后,它们会由第一个六角形开始保持冰晶的形 I do not know if you did not notice it. In winter, when the temperature is below zero degrees Celsius, when the snowflakes are formed, tiny ice crystals will gradually come to condense into ice nuclei, and snowflakes will also be born. This process is called “Crystallization”. During crystallization, water molecules change from liquid to solid in their basic arrangement. Since the basic pattern of ice crystals is a hexagonal prism, most of the prototype ice crystals are hexagonal. As more molecules of water combine with the ice crystals, they begin to form ice crystals from the first hexagon
