These changing constraints tend to get lost in a " monolithic " class diagram that does not take state into account 这些不断更改的约束在不考虑状态的“单态”类关系图中容易丢失。
This paper defines homology monomorphism , homology epimorphism , homology regular morphism in the category of topological spaces with point by using homology functor 摘要利用同调函子,在点标拓扑空间范畴中定义了同调单态、同调满态、同调正则态射等概念。
For clusters of 13 nd 25 sites with the special shape , the numerical results show that their gs are respectively 6 - fold and 8 - fold degeneracy ( while the gs of macroscopic antiferromagnet is singlet ) 通过计算含有13个格点和25个格点的双组分海森堡反铁磁团簇,结果表明它们的基态分别是6重和8重态(而宏观反铁磁系统的基态是单态) 。
The findings , which appear in the september issue of molecular cell , not only advance knowledge of how cells sense the presence of singlet oxygen , but also how they turn on critical genes to defend themselves from its effects 该发现刊登在分子细胞杂志的9月刊号上,它不仅增进了我们对细胞如何感受单态氧这种机制的了解,而且还揭示了细胞如何开启关键基因的表达来防御单态氧带来的损伤。
