摘　　要：利用圈量子引力中自旋网顶角定义的一种新的体积不变量,给出"2+1"维和"3+1"维空时单形跃迁的振幅,得到了自旋网跃迁过程中空间体积膨胀的结果.将这一结果引入空间编织理论之中,提出了一种基于空间跃迁中由于体积本征值改变的宇宙量子膨胀模型.同时利用量子四面体提供的量子信息,对引力场的产生提出了一种解释.Using a new volume invariant defined by vertex of spin network, the transition amplitude of ＂2＋1＂ and ＂3-＋-1＂ dimension simplexes are given, and the result of volume inflation of space is obtained during the process of the spin networks transition. Considering this mechanism in the space weaving theory, a universe inflation model based on volume change of spacetime transition is proposed. At the same time, by use of the quantum information given by the tetrahedron, for the emergence of gravitational field an explanation is argued.
