JB环氧沥青新材料处理路面早期病害探讨

某公路工程建成通车的运行良好,然而近期发现沥青混凝土路面发现裂缝和龟裂病害,避免雨水渗透道路面基层,损害道路性能质量,开始将新材料应用到路面病害处理中。在这研究主要是探讨JB环氧沥青新材料处理路面早期病害的效果,希望能够对相关人员起到参考性价值。

JB_∞- 环

研究了JB∞-环,即满足R/J(R)是QB∞-环,得到了很多J B∞-环的判定条件:R是JB∞-环当且仅当对任意满足条件a R+b R=R的a,b∈R,存在y∈R使得a+by∈R-1J∞当且仅当对任意满足条件a R+b R=d R的a,b,d∈R,存在y∈R,u∈R-1∞使得a+by=du.另外还讨论了替换环是JB∞-环的充分必要条件,这些结论对QB∞-环提供了一些研究基础.

On JB-Rings

A ring R is a QB-ring provided that aR ＋ bR = R with a, b E R implies that there exists a y E R such that a＋ by ∈ Rq^-1. It is said that a ring R is a JB-ring provided that R/J（R） is a QB-ring, where J（R） is the Jacobson radical of R. In this paper, various necessary and sufficient conditions, under which a ring is a JB-ring, are established. It is proved that JB-rings can be characterized by pseudo-similarity. Furthermore, the author proves that R is a JB-ring iff so is R/J（R）^2.
