摘　　要：首次报道130Ce、129Ce和128Ce的(EC+β+)衰变纲图,其中包括核素的产生、核素的分离鉴别以及纲图的建立。着重补充了一些重要的技术细节,更新了129Ce的衰变纲图,并对这些纲图中涉及的物理问题进行了讨论。The （EC＋β^＋） decay schemes of ^130Ce,^129Ce and ^128Ce, those were first reported by our group, have been reviewed, including the production, separation and identification as well as the proposed decay schemes of the three nuclides. In addition, important technical details have been added, the decay scheme of ^129Ce has been revised and the physics related to the three decay schemes have been discussed.
