heat diffusion

基本解釋

In this article the analytical calculation has been made for the evaporator heat transfer in absorption-diffusion refrigeration system with the annular two-phase two-component heat transfer model.
本文采用雙組分環(huán)狀二相流模型對吸收-擴散式制冷系統(tǒng)蒸發(fā)器的傳熱進行了分析計算。
Based on the reasonable assumption, a numeric model describing the process of axial heat conduction and gas-solid two phase diffusion within porous composite desiccant wheel was set up and solved.
基于合理的假設(shè)條件，建立了同時考慮軸向?qū)?、質(zhì)擴散以及多孔結(jié)構(gòu)的數(shù)學模型，對硅膠基復合干燥劑轉(zhuǎn)輪的傳熱傳質(zhì)過程進行了數(shù)值模擬計算。
Coatings become smoother and denser after heat-treated in a H2 atmosphere through the diffusion of newly reduced Co atoms driven by the surface energy reduction.
氫熱處理使化學鍍層變得致密光滑，還原生成的金屬原子的擴散是鍍層形貌和結(jié)構(gòu)演變的主要途徑，而表面能的下降則是形貌演變的驅(qū)動力。
