摘　　要：分别测量了含０．００、０．０１、０．０３、０．０５、００７、０．１０ｗｔ％Ａｓ的６８ｗｔ％Ｃｕ－Ｚｎ合金在１％ＣｕＣｌ２水溶液中脱锌后的正电子寿命谱。讨论了黄铜脱锌及砷抑制脱锌的空位体扩散机制。Positron lifetimes have been measured for 68wt% Cu-Zn brass containing 0.00.0.01, 0.03,0.05,0.07 and 0.10 wt% As respectively after dezincification in 1%, CuCl2aqueous solution.The vacancy mechanism of the brass dezincification and the inhibition of brass dezincification by arsenic have been discussed.
