【摘要】 最近国外报道把ＥＭＤ粉末等制成湿度敏感器的技术，但对其作用机理的解释尚有欠妥之处，本文除简介此类湿度敏感器的工艺之外，还利用我们研究水蒸气对ＥＭＤｏＡ附的理论予以阐释，并确认其合理与否更多还原

【Abstract】 Recently,the techniques of humidity sensors making by using EMD-basedmanganese oxides have been reported in foreign magazine,However,there st ll exists ambi-guity in the interpretation of the reaction mechanism. In this paper,we shall recommend the technique of humidity sensors making and the interpretation by our theory cf the adsorptionof water vapor on EMD samples,on the basis of the theory we have discussed we shall de-cide the feasibility of the humidity sensors.更多还原
