摘　　要：研究了C.F.Lo定义的广义多模压缩态(Phys.Rev.A 47 733-735)在N=3时的三模压缩态与介观约瑟夫森结超导环相互作用时超导电流期望值随时间演化的情况。在三模量子化光场的模与模之间的压缩参数不相同的情况下,探究了超导电流时间演化的量子坍塌复苏现象与压缩参数的关系。Time evolution of the supercurrent in mesoscopic Josephson junctions has been studied when junctions interacted with three -mode squeezed electromagnetic field （defined by C. F. Lo in Phys. Rev. A V47 733 - 735, when generalized multimode squeezed states at ）. The relation between quantum collapse and revival phenomenon in time evolution of the supercurrent and squeezing parameter with different mode - and - mode parameters of the three -mode quanfized electromagnetic field is showed.
