The sample is introduced and the new volume recorded. The difference is the bulkvolume of the sample.
然后把样品放到容器中，记录此时的新体积，前后体积之差就是样品的体积。

Porosity is defined as the ratio of the void space in a rock to the bulkvolume of that rock multiplied by 100 to express in percent.
孔隙度定义为岩石内的孔隙体积占岩石总体积的百分率。

By the density test of blow-drying and stoving of non-aridity core sample from asphalt pavement, the bulkvolume relative density and compactness can be calculated under different test conditions.
