boundary layer diffusion

基本解釋

In a fully developed convective boundary layer, the variation of vertical diffusion coefficients increases with height.
在充分發(fā)展的對(duì)流邊界層中，垂直擴(kuò)散系數(shù)隨高度的增加而加大。
This impervious layer or boundary will retard the free diffusion of moisture. This condition is referred to as case hardening.
這一不透氣的殼層(或邊界層)會(huì)阻滯水分自由擴(kuò)散，這種情形稱爲(wèi)表麪硬化。
Therefore, in the convective boundary layer the variation of vertical diffusion coefficients obtained from the Doppler acoustic radar can express the diffusion process well.
用聲雷達(dá)測(cè)量的垂直擴(kuò)散系數(shù)能夠較好地反映對(duì)流邊界層中的擴(kuò)散過(guò)程。
