比密度 [bǐ mì dù]
specific density
- 因为大多数物质再结冰的时候会缩小，所以物质的固态比液态密度打。
Most substance contract when they freeze so that the density of a substance's solid is higher than the density of its liquid. - 它几乎有木星——我们太阳系最大的行星——的1.5倍大。而且它比水的密度更小。
It is almost one and half times bigger than Jupiter -- the largest planet in our solar system. And it is less dense than water. - 当填料密度比液体密度小时，在液泛前填料会发生松动和膨胀，通过修正填料床的孔隙度可以计算膨胀填料床的压降。
When the density of the packing material is smaller than that of the liquid, the packed bed becomes less dense and will expand before flooding.
