Delegation step, delegation unit and their dependency relationships are defined to formally describe inherent restriction relationships between flow tasks.
鉴于现有网格虚拟组织访问控制模型没有对网格工作流授权提供有力的支持,该文提出一种网格工作流访问控制模型GWACM,定义了委托步和委托结构体以及它们之间的依赖关系,形式化地描述了流程任务间的内在约束关系,阐述了委托步的生命周期模型。

提出委托凭证以细粒度地表示授权决策结果,定义了委托步和委托结构体以及它们之间的依赖关系以形式化地描述流程任务之间的内在约束关系。
AM1 semi-empirical quantum-mechanical simulations are performed to obtain the geometrical configuration,electronic structure,molecular energy,hydrophobic constant log P,polarizability,and dipole moment for three kinds of C120 isomers-linear 2C60 polymer,peanut-like 2C60 polymer and C120 fullerene.
以哑铃状2C60聚合体、花生壳状2C60聚合体以及C120富勒烯分子为研究对象,采用AM1半经验量子化学方法,计算了3种C120异构富勒烯分子的几何构型、电子结构、分子能量、疏水常数、极化率与偶极矩;然后,根据计算结果,分析对比了3种C120异构体分子的化学稳定性与物理化学特性。
