摘　　要：The abnormal thermal expansion of Bi based high Tc ( HTC) superconductor Bi2 Sr2 Ca2 Cu3 O10( Tc = 105 K) isstudied quantum mechanically and phenomenologically. Itisshown thatthe abnormalexpansion behaviorisof relevancetothe differentenergy ab sorption mechanismsofsuperconducting and normalstatesand pairing mechanisms.The abnormal thermal expansion of Bi based high Tc ( HTC) superconductor Bi2 Sr2 Ca2 Cu3 O10( Tc = 105 K) isstudied quantum mechanically and phenomenologically.
