完美的雪花的照片

Snowflakes — those intricate, one-of-a-kind ice crystals — form when precipitation falls through varying levels of humidity and temperatures in the air. While plenty has been written about the science of snow, we're focusing on the sheer beauty of them. Here are some to study and admire, with a nod to some beautiful frost as well.

雪花——那些复杂的、独一无二的冰晶——是在空气中不同湿度和温度的降水过程中形成的。虽然已经有很多关于雪的科学的文章，但我们现在关注的是雪的纯粹之美。这里有一些值得研究和欣赏的照片，还有一些美丽的霜冻。
