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(kuò)散控制晶界滑動(dòng)是低溫超塑行爲(wèi)的主要機(jī)理。
The adsorption process followed the pseudo-second order model and intraparticle diffusion and boundary diffusion control the adsorption together.
動(dòng)力學(xué)實(shí)騐表明，吸附反應(yīng)遵循準(zhǔn)二級(jí)動(dòng)力學(xué)模型，且粒內(nèi)擴(kuò)散和邊界層擴(kuò)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(kuò)散是以晶界擴(kuò)散爲(wèi)主，晶界擴(kuò)散系數(shù)遠(yuǎn)遠(yuǎn)大於晶內(nèi)的擴(kuò)散系數(shù)。
