1)  acyclicity
非环性
1.
We gave a new algorithm for recognizing four type acyclic database schemes(namely: Alpha-,Beta-,Gamma-,Berge-acyclicity) by using the line graph of the scheme in a distributed environment.
介绍一个在分部式环境下,用线图模型识别数据库模式的四种常见非环性(即,Alpha,Beta,Gamma,Berge非环性)的算法DPRE,并证明该算法的最坏消息复杂度为O(|E|),其中|E|表示数据库中有公共属性的关系对之总数。
2)  noncyclic polyether
非环多醚
1.
The mass spectra of ureide-type noncyclic polyethers with 2(3H)-benzoxazolone as end groups were studies.
研究了以2(3H)-苯并唑酮为端基、具有酰脲结构的非环多醚化合物的质谱。
2.
Eight noncyclic polyethers with 2(3H)-benzoxazolone or benzotriazole as end groups were synthesized.
由于非环多醚化合物分子可以根据其不同的化学结构而呈现不同的柔曲性,因而可能选择性地络合具有不同离子半径的金属离子。
