Compare the melting point and freezing point of a substance.
应该考虑到这种物质的熔点低。
Account should be taken of the low melting point of this substance.
这两组行星的构成物质根据熔点分为三类：气体、岩石和冰。
The substances that make up both groups of planets are divided into three groups—gases, rocks, and ices—based on their melting points.
介绍凝固点下降薄层比较法测量熔点标准物质熔点的测量装置的构成与工作原理。
