| 1. | It has a universal property .
它具有泛性质。 |
| 2. | Do such plots show universal properties
这些图显示出了普遍性质吗？ |
| 3. | Owing to providing a database interface for electronic map , the system has well open and universal property
由于本系统提供了电子地图数据库接口，因此具有很好的开放性和通用性。 |
| 4. | It solves the problem of bad universal property of the usual welding torch system , which makes use of gas driving or liquid pressure
解决了常规焊枪运动系统采用气动或液压而通用性不佳问题。 |
| 5. | Xml files are used to store product design data . it has good universal property and expansibility and is easy to communication online
系统采用xml文档结构化存储设计数据，具有良好的通用性和扩展性，便于在网络上的传输。 |
| 6. | Furthermore , structure a kind of commutative semirings . namely fractional semiring . then , we prove a universal property of fractional semiring , and we discuss the relations between the ideals of commutative semirings and the ideals of fractional semirings
然后，我们证明了分式半环的泛性质，并且讨论了分式半环与交换半环理想之间的关系 |
| 7. | Using universal property , we can define general ( pre ) cover and ( pre ) envelope , such as gorenstein injective ( projective or flat ) ( pre ) cover and ( pre ) envelope , 5 - torsion free ( pre ) cover etc . in a word , problems on ( pre ) over and ( pre ) envelope have aroused considerable debate in the academic circle , which embodies flexible use of tools of homological algebra in studying categories of rings and modules
而且利用泛性我们又可定义更广泛意义上的包、盖问题，例如： gorenstin内射(平坦、投射)包(盖) ， s -无挠预盖，等等。用这类比内射(平坦、投射)更广泛意义上的特殊模又能刻画一些环。总之，包、盖问题是当今非常活跃的研究课题，体现了同调代数在环模范畴研究中灵活运用。 |
