英文摘要	循环伏安量热法研究了欠电位沉积条件下，铜在ＬｉＣｌＯ＿４溶液中，铂电极上的电沉积过程，循环伏安热谱图和循环伏安微分热谱图表明，铜离子的电沉积为一放热过程．其中铜～铂（层）相互作用能为－３２２７．０ｋＪ／ｍｏｌ．沉积铜的电氧化包括了吸热的活化和放热的氧化两个过程．活化过程的焓变为７４７．０ｋＪ／ｍｏｌ，氧化过程的焓变为－１８９．９ｋＪ／ｍｏｌ，与热力学数据一致．; In the present paper,cyclic voltammetric calorimetry has been used to study thedeposition of copper on platinum electrode from LiClO_4 aqueous solution. Cyclic voltammetricthermogram and cyclic voltammetric differential thermogram show that the deposition of copper on theelectrode is an exothermal process with a strong interaction between copper and platinum layer(-3227.0 kJ /mol).The electrochemical oxidation of the deposited copper is composed of twoprocesses :an endothermal activation process with 747.0 kJ/mol of activation enthalpy,and anexothermal oxidation reaction with-189.9 kJ/mol of the reaction enthalpy, which are accord withthe data from the theoritical estimation and thermodynamic handbook respectively.; 作者联系地址：沈阳医学院; Author's Address: Shenyang Medical College,Shenyang 110031University College London,London,WC1HOAJ
