2)  AP-injective rings
AP-内射环
1.
In this paper,we mainly prove that right P-V′ and right AP-injective rings are left nonsingular and discuss the regularity of right nonsingular AP-injective rings.
主要证明了右P-V′、右AP-内射环是左非奇异的,并且研究了非奇异的AP-内射环的正则性。
2.
The purpose of this paper is to study the following two questions on AP-injective rings: (1) R is a regular ring if and only if R is a left PP-ring and R is left AP-injective; (2) Let R be a right .
本文的主要目的是讨论AP-内射环中的两个问题:(1)环R是正则的当且仅当R是左AP-内射的左PP-环;(2)如果R是左AP-内射环,那么R是内射环当且仅当R是弱内射环。

We combined the known properties of quasi AP-injective modules with the way of studying quasi P-injective modules to give some new properties on quasi AP-injective module.
把拟AP-内射模的已有性质与拟P-内射模的研究方法相结合,给出了拟AP-内射模的一些新性质。
5)  AP ring
AP环
1.
Moreover,the PP rings are extended to AP rings,and some more general results about AP rings are obtained.
同时,用GP-内射环刻画了GPP环,把PP环推广到了AP环,并且得到了比PP环更广泛的结果。

补充资料:双酚AP型环氧树脂(bisphenol-AP type epoxy resin)
分子式:
CAS号:

性质:俗称双酚AP型环氧树脂(bisphenol-AP type epoxy resin)。分子链含有双酚AP结构的缩水甘油醚型环氧树脂。分子量540~640,软化温度100~120℃。固化物断裂伸长率5%~7%。玻纤增强塑料压缩强度392MPa,弯曲强度622.3MPa,剪切强度41.2MPa(150℃时2.94MPa)。由季戊四醇、丙烯醛和苯酚制成双酚AP后,再与环氧氯丙烷缩聚制得。加工方法与双酚A型环氧树脂相似。主要用作玻纤缠绕结构材料如高压容器等。
