摘要
气体透过法已经被用来测量粉末的比表面和粒度。细粉末和超微粉末在稳定流动下,伴随有分子流效应。这个效应,30多年来没有从计算上很好解决。本文已解决此问题。
The gas permeating method has been used in measuring both specific surface
and particle size for powders. Ultra-fine and fine powders, are made after the
molecular flow effect under the steady flow. The effect, has not been calculated
very well for thirty years. This work has solved the problem perfectly.
