Followed, it concucts increasing coproduct steam and unit energy cost in the process of methanol refined is reduced. 同时副产蒸汽增多,甲醇精制过程单位能耗降低。
At last, we study the finite topological property of the category L-FG, andgive out the concrete constructions of finite product and finite coproduct. 最后，研究了L-图范畴L-FG的有限拓扑性质，给出了L-图范畴L-FG的有限积和有限余积的具体构造。
NI Shen-bing.Weak Hopf algebras's twisted Smash product and Smach coproduct [J].J of Zhejiang University (Science Edition), 2002, 29(3): 268-273. [8]倪沈冰.;弱Hopf代数的扭曲的Smash积及Smash余积[J]
Precipitation of metals under hydrothermal conditions has the advantage of a compact plant but the disadvantage of producing ammonium sulfate as a coproduct. 金属在湿法加热条件下沉淀有利的是设备密实,不利的是产出了副产品硫酸铵;
In this paper, we define fuzzy modules over interval-valued fuzzy rings and study itsProp-erties, we also define categories of fuzzy modules over interval-valued fuzzy rings and study its product and coproduct. 定义了区间值模糊环上的模糊模的概念;讨论了它的性质;并定义了区间值模糊环上模糊模范畴的概念;研究了它的积与余积的性质.
Last but not the least, according to the pushouts category , we obtain the theory of triangular commutative diagram and give the necessary condition of the coknernel and coproduct. 最后,证明了两个命题,它们是本文主要结论的基础。第二个部分,给出了推出范畴中的几个重要定理:推出范畴中上核存在的必要条件;三角可换定理;在有上积的范畴的推出范畴中,上积存在的必要条件;
