Abstract: Aiming at the question of lack study about relationship of weak notion properties.Based on a view that people design agent system as agency of individual or social action.Discuss weak notion properties and these properties relationship，bring forward that satisfying weak notion means a agent has autonomy and social property.Define a model to satisfy the weak notion（AS_Agent），discuss its logic structure and work process.Through comparing properties weak notion to object properties， AS_Agent is reusable more than object model.

摘要： 针对缺少Agent弱概念特性间相互关系研究的问题，基于人们设计Agent系统的目的之一是把它们作为人类个体或社会行为的智能代理，文章直观讨论了弱概念特性和特性间的关系，认为满足弱概念是指具备自治性和社会性的Agent。定义了一种满足弱概念的混合型Agent（AS_ Agent）模型，论述了AS_Agent的逻辑结构和基本工作过程。文章还比较了弱概念特性和对象特性，认为满足弱概念的Agent比对象具有更好的可复用性的潜能。
