X-射线荧光光谱定性解释专家系统

Application of Forgetting Factor and Other Computational Method in Spectrophotometry

本文提出了解释X-射线荧光光谱领域知识的“谓词——规则——过程”表示法,提出了专家系统工作数据库的“主——支”链数据结构.进行了专家系统用于该领域时推理机制和控制策略的研究,建立了X-射线荧光光谱定性解释专家系统。该系统解释人工合成样品P_(12)的结果准确率为87％,解释钢样品的结果与领域专家的解释完全吻合。该专家系统的性能已接近领域专家的水平。

This paper involves the study on forgetting factor spectrophotometry and other computational method such as least square, kalman filtering, linear programming, principle components regression, P-matrix algorithm and partial least square. The analytical results show that forgetting factor method in spectrophotometry has its own merits.
