snow crystal

基本解釋

Silicate materials – clay minerals and micas – can act as the core of a fledgling snow crystal.
硅酸鹽物質(zhì)——包括粘土礦物和云母——會(huì)成為剛成型的雪花冰晶的核心。
Water molecules join together in a rigid pattern – a tiny ice structure that’s the heart of a snow crystal.
水分子連接成堅(jiān)固的結(jié)構(gòu)排布，這一小小的冰結(jié)構(gòu)是雪花晶體的核心。
Why snow crystal shapes change from thin, flat plates to long, slender needles when the temperature changes remains something of a scientific mystery.
為什么在溫度變化時(shí)雪晶的形狀也隨著變化，從薄且平的盤狀變成長(zhǎng)且細(xì)的針狀，這仍是一個(gè)科學(xué)之謎。

The shape of a snow crystal may change from one form to another as the crystal passes through levels of air with different temperatures.
Soon the sun's warmth makes them shed crystal shells - Shattering and avalanching on the snow crust-- Such heaps of broken glass to sweep away You'd think the inner dome of heaven had fallen.
陽(yáng)光的溫暖接著使那水晶的硬殼,從樹枝上崩落，一齊傾瀉在雪地上-,這么一大堆碎玻璃盡夠你打掃,你還以為是天頂?shù)娜A蓋塌了下來(lái)。
耶魯公開課 - 現(xiàn)代詩(shī)歌課程節(jié)選
Soon the sun's warmth makes them shed crystal shells Shattering and avalanching on the snow-crust-- Such heaps of broken glass to sweep away You'd think the inner dome of heaven had fallen.

To illustrate, consider how a quickly flowing stream forms stable eddies as it curls around a boulder, or how a snow crystal spontaneously grows its precise, hexagonally symmetric, yet idiosyncratic branches.
