According to finite element segmentation principle, by combining test with observation, the author has measured the air streamline and speed distribution of burning equipment in dally situation, which provides some guide for research of air field in hearth on cold and hot conditions. and the law is found of air speed distribution by measuring its speed and distribution of upper and lower deck on cold condition, thus it lays the foundation for analysis on hot condition. under four burning states, we measure the air speed in single, double - deck, and find out its corresponding distribution law
5 .根據有限元分割原理布置測點，採用降溫方法，用k五江9106等儀器分別測出單雙爐排燃燒方式4種不同工況下，該燃燒設備爐膛內coz 、 02 、 co氣體濃度，並找到了隨爐膛高度方向及深度方向變化規律;從燃燒原理分析評價了2種燃燒方式爐膛內coz 、 02 、 co氣體濃度場分佈特點及相應燃料層內乾燥、干餾、氧化、還原、灰渣層厚度，肯定了雙層爐排燃燒方式爐膛中c02 、 02 、 co氣體濃度場分佈合理性，從燃燒理論找出了最佳濃度場分佈狀態及燃料層內各反應層厚度。The key part of proton exchange membrane fuel cells ( pemfc ) is membrane electrode assembly ( mea ), where mass transfer processes and electrochemical reactions proceed simultaneously. the accurate, systematic and in - deepth acquaintance with mea has not been obtained yet. so a comprehensive study about mea is completely necessary
質子交換膜燃料電池（ pemfc ）的膜電極中包含多種傳輸過程，且傳輸過程與電化學反應過程在相互交錯的區域內進行，目前人們對膜電極的結構、傳輸過程和電極的微觀性質還缺乏準確、系統和深層次的認識。
