It is the result of the stretch that the widened peaks are incompatible with a B-centered orthorhombic bravais lattice , and the intensities of satellites become asymmetry. The superlattice based on the lattice mismatch is not orthorhombic but monoclinic and perhaps forms superlattice twin structure in Bi-2212 single crystals. %K BSCCO %K 超导体 %K 单晶调制结构 %K X衍射 %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=6E709DC38FA1D09A4B578DD0906875B5B44D4D294832BB8E&cid=47EA7CFDDEBB28E0&jid=29DF2CB55EF687E7EFA80DFD4B978260&aid=7411BF4698E83734454B0FD2E7529925&yid=8A15F8B0AA0E5323&vid=94E7F66E6C42FA23&iid=9CF7A0430CBB2DFD&sid=6DC9B9BB39B3E540&eid=A7E1C896834B988A&journal_id=1000-3290&journal_name=物理学报&referenced_num=0&reference_num=3
