| 1. | For example , when we see a snowflake with plate - like shape and needles - like arms , we can guess that when this snowflake was formed , the temperature was between - 5c and - 20c so that a plate - like ball could be generated , and then the temperature got warm to between 0c and - 5c for it to get the needle arms
例如,我们能够看到一个片状主体时,温度大约介乎摄氏零下五度至零下二十度.如果温度变暖至介乎摄氏零度至五度,针状分支便会形成.此外,雪花在空气中飘浮的时间越长,图案会越复杂 |
