Article 4: The formation mechanism of substance boundary layers /物质在各形态中的分层与边界形成机制:
Author: Liu Huan, MSc (First Class Honours), The University of Auckland.
In the three-dimension materials space, the boundaries commonly exists among the materials of solid state, liquid state or gas state. For example, atmosphere is divided into troposphere and stratosphere by the clear boundary layer between both; the water temperature is divided into different thermal layers along the depth of a lake by the clear boundary between water layers; apparent lithologic stratification is segregated by the geological boundary between them.
The formation of substance boundary: the polarity of polar molecules and atoms (or the induced van der Waals force of non-polar molecules and atoms) leads to the symmetrical arrangement between positive and negative poles. As the whole substances, it tends to be a neutral substance boundary. This neutral substance boundary becomes the obstacle stopping the polar substances from the transmission through it, resulting in different substance layers.
