摘　　要：本文对单晶性很好的Ｂｉ２Ｓｒ２ＣａＣｕＯ８ － ｘ 进行了插碘，得到完好的插层晶体．尽管碘的插入导致晶胞在ｃ 方向增长了约０ ．３５ｎｍ ，其电阻测量的结果与未插层单晶行为相似，只是Ｔｃ 略有下降，意味着ＣｕＯ面内的载流子浓度没有明显的改变．Intercalation of iodine into single crystal specimen of Bi 2Sr 2CaCuO 8- x was synthesized, and perfect intercalation compound was obtained. Although the intercalation of iodine led to a expansion of the unit cell of 0.35nm, the result of resistivity measurement showed it is similar to the original crystal except that T c reduced a little, which suggested little change of carrier concentration in the CuO 2 plane.
