Marcasite is more crystalline . it produces even more of the glittery , shining tiny crystals than pyrites 因其永不褪色的獨(dú)特光澤,易于搭配,多鑲嵌在各類(lèi)首飾上,裝飾感極強(qiáng)。
Opals get their milky sheen and rainbow sparkle from the way light is scattered by the tiny crystals that form them 貓眼石呈現(xiàn)出乳白色光澤和彩虹般光芒,這是由構(gòu)成貓眼石的微小晶體散射光線(xiàn)而形成的。
Opals get their milky sheen and rainbow sparkle from the way light is scattered by the tiny crystals that form them 貓眼石乳白色的光澤和彩虹般的光芒是由于進(jìn)入其內(nèi)的光線(xiàn)被組成其的微小晶體所分散成的。
But careful studies of microscopic , magma - filled bubbles trapped inside tiny crystals of quartz tell a different story 但是,詳細(xì)研究石英的微小晶體內(nèi)那些僅能在顯微鏡下看到、充填著巖漿的氣泡,則令我們發(fā)現(xiàn)了不同的故事。
Snow particles fall at rates ranging from nearly zero for tiny crystals to about a metre per second for a typical snowflake and several times larger for melting snow 雪粒子由天上降至地上的度快慢各異,極小的晶體下降度近乎零,一般雪花則以每秒一米的速度,溶化中的雪還要快好幾倍
