adj.取决于粒子数目的

The four properties, vapour pressure lowering, freezing point depression, boiling elevation, and osmotic pressure, are known as the colligative properties of solutions. 溶液的这四个特性：蒸汽压下降、凝固点降低，沸点升高和渗透压，称为溶液的依数性。

That is what makes vapor pressure lowering a colligative property--it only depends on the number of dissolved solute particles. 这使得蒸气压降低1 colligative财产-它不仅取决于一些溶解溶质粒子。

There are several other properties of solutions, besides concentration and solubility, called colligative properties, that depend only on the number of solute particles, not on their identities. 还有其他一些性能的解决方案，除了浓度和溶解度，所谓colligative性质，即仅仅依靠数量的溶质粒子，而不是对他们的身份。colligative性质的，我们将研究的蒸气压降低，凝固点抑郁，沸点海拔和渗透压。
