boundary layer diffusion

基本解释

In a fully developed convective boundary layer, the variation of vertical diffusion coefficients increases with height.
在充分發展的對流邊界層中，垂直擴散系數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)會阻滯水分自由擴散，這種情形稱爲表麪硬化。
Therefore, in the convective boundary layer the variation of vertical diffusion coefficients obtained from the Doppler acoustic radar can express the diffusion process well.
用聲雷達測量的垂直擴散系數能夠較好地反映對流邊界層中的擴散過程。
