英文摘要	Ｚｒ（Ｖ＿（０．２）Ｍｎ＿（０．２）Ｍｏ＿（０．０６）Ｎｉ＿（０．５４））＿（２．４）合金经ＨＦ溶液处理后，合金表面由富Ｚｒ和富Ｍｎ层转变成富Ｎｉ层，从而使电极初期活化周期明显缩短，电极表面氢吸附性能改善，表面反应电阻减小。本文探讨了上述电极表面反应机理，即表面Ｎｉ的催化、氢吸附和氢转移机理。对阻抗谱进行拟合，给出了相应的电极反应等效电路。; After treated by HF solution,the surface of Zr(V_(0.2)Mn_(0.2)Ni_(0.54)Mo_(0.06))_(2.4) alloywas transformed from Zr-rich and Mn-rich layer to Ni-rich layer.In this way,the nickel on thesurface could be believed to be the Raney-type nickel, which could obviously shorten the activationcycles,improve electrocatalytic activity and hydrogen adsorption ability.In this paper,the reactionmechanism on the alloy surface(i.e. the mechanism of nickel-catalysis,hydrogen-adsorption andhydrogen-transference)had been investigated.And the impedance spectra were fitted to an equivalentcircuit using a non-linear,least-squares(NLLS)fitting program.; 作者联系地址：南开大学新能源材料化学研究所; Author's Address: Institute of New Enorgy Material Chemistry,Nankai University,Tianjin 300071
