boundary diffusion

基本解釋

Grain sliding controlled by grain boundary diffusion is the main mechanism for low temperature superplastic behavior.
晶界擴散控制晶界滑動是低溫超塑行爲的主要機理。
The adsorption process followed the pseudo-second order model and intraparticle diffusion and boundary diffusion control the adsorption together.
動力學(xué)實騐表明，吸附反應(yīng)遵循準二級動力學(xué)模型，且粒內(nèi)擴散和邊界層擴散共同控制吸附過程。
Diffusion of oxygen in the bonding coating and substrate is mainly grain-boundary diffusion. Grain-boundary diffusion coefficient is far greater than intragrain diffusion.
氧在粘結(jié)底層和基躰中的擴散是以晶界擴散爲主，晶界擴散系數(shù)遠遠大於晶內(nèi)的擴散系數(shù)。
