direct limit meaning in English

方向极限
归纳极限
正向极限

In the last section , we discuss the covers and envelopes both of which are of great importance in the field of ring theories . by the morita context functors we can transform from rx - cover ( envelope ) into sx - f - cover ( envelope ) . finally they are further characterized by the particular properties of the direct limit
在第四部分中，我们对环论中十分重要的内容? ?包与盖进行探讨，通过一类特殊的模范畴_ rx ( _ sx ) ，使_ rx -包(盖)在moritacontext函子作用下转化为_ sx -包(盖) ，最后利用正向极限的特性，进一步刻画这类特殊的包与盖。
Abstract : direct limit and inverse limit are the methods producing new algebra in universal algebra . in order to further study the production of the new algebra , authors define the family of duplicate set and duplicate limit , discuss the algebraic duplicate limit , the characterestics of the once more duplicate direct set and more duplicate direct limit , the family of once more duplicate direct direct algebra and the limit of once more duplicate algebraic set family
文摘:直极限和逆极限是泛代数中生成新代数的方法，为了进一步研究新代数的生成，笔者给出了重集族和重极限的定义，讨论了代数的重极限；其次研究了二重直集族和二重直极限及相应性质，讨论了二重直代数族和二重直代数族的极限
