金属材料拉伸特性曲线特征数据的自动求取

Auto-quest Feather Data of Extended Curve in metal Material

本文对金属材料拉伸曲线特性数据的自动求取进行了详尽的分析与研究，利用计算机的软件编程对拉伸曲线特征数据进行求取，克服了传统的人工测量人工计算带来的诸多不便和测量误差。研究发现，通过软件可以实现对工程应用测量曲线的准确处理和分析，并进行相应的闭环自动控制，具有一定的通用性。

A new method which auto-quest the feature param of extend curve is present in this paper.We have tried out this mehod by computer programming and got the accurate result. After comparingthe measure result with that calcu1ated in traditional hand-measuring way we find the program couldgreatly improved the accuracy and eliminated the erro basically. After reaserching, we can draw a con-cIusion that this method is not only used in this paper but also adapt to general measure curve in otherfields.
