Abstract The feature and the issues associated with it,including its definition,representation and multi viewpoint, were discussed in detail. The feature modeling and the design based on constraint were analyzed.The viewpoint that feature is an entity or abstractor with special meanings based on application fields was proposed.On analyzing the dynamics characteristics of rotatory machine, a system based on feature and object orientated technology was constructed.The paper laid the foundation for developing application system based on feature and object orientated technology.

特征及其应用
对目前研究较多的特征及相关问题进行了分析，包括特征的定义、表达、特征的多视角问题等。对特征造型
方法和基于约束的设计进行了讨论。提出特征是某一应用领域内具有特定意义的实体或抽象体。建立了基于特征
思想和面向对象实现技术的旋转机械动力特性分析系统。本文的工作为下一步开发面向对象和基于特征的系统提
供了基础。
