filtered degree

 filter is defined by introducing  operator in BR0-algebras,and based on that the concept of submaximal  filter is given.

首先在BR0代数M中引入滤子,然后又给出了M中次极大滤子的概念,并讨论了它的性质,得到了BR0代数中的每个滤子都可表示为一些次极大滤子的交的结果。

On the basis of the generalized invariant theory, the invariant-related unitary transfoumation method is developed and used to study the evolution of the third-quantized wave function of the universe.

首先在推广了的量子不变量理论的基础上建立了与不变量有关的立正变换方法，并用此方法研究了三次量子化宇宙波函数的演化，求得了系统的相因子、波函数。
