The extensible schemes based on symbol representation are much useful in computer animation and industrial prototype design application .

由于该方法基于 符号表示，因此易于实现与扩展，适合于 计算机动画造型和工业原型 设计。

By setting up a hierarchical mechanism motion model for conceptual design through the formal description of function symbol we provide a solid support to the computer aided conceptual motion design .

通过功能 符号形式化描述建立分层次的机构概念运动模型，实现对 计算机辅助概念运动 设计的支持。

This method put forward in this paper lays the foundation for embodying symbol scheme into three-dimensional entity at the same time it also makes condition for computer aided conceptual design of complex mechanical system based on basic mechanisms .

符号方案的自动识别为 符号方案三维实体化打下了基础，同时也为基于基本机构的复杂机械系统的 计算机辅助概念 设计创造了条件。
