本文的目的,首先封於可数无限階的分立赋值体证明其极大性舆完全性等價,其次,把问题反转,设给有一個可数无限階的赋值体(因之,封有限階的赋值体也成立),其完全性舆极大性等價,則这個赋值必然是分立赋值。从这两方面的结果,我们就得出一個关於可数无限階(因之,也是有限階)的分立赋值体的刻画了。 The purpose of this paper is first to prove that a discrete assignment of infinite order has its maximal completeness equivalence. Secondly, to reverse the problem, there is a set of infinitely valued assignment bodies The order of the body also set up), its completeness of the world is equivalent, then the assignment must be discrete assignment. From these two results, we arrive at a portrayal of discrete assignments of infinite order (and therefore of finite order).
