【摘要】 采用模糊集有关理论对所有可能影响保留指数定性准确度因素通过隶属函数表示出来。本方法弃之以传统“定性窗口”的概念,代之以隶属度,并根据最大隶属原则定性。不仅如此,本方法尚具有“窗口”定性法不具备的多种优点,使得定性可靠性大大增加。而且本方法还为定性结果优化、因素校正提供了有效的手段。经过对任意多阶方式下石脑油组分定性分析证明了其特有的作用。更多还原

【Abstract】 Peak identification in gas chromatography is based on comparison of peak retention values between analytes and standards.In order to describethe uncertainty of retention,membership functions have been derived for the identification process.Such a fuzzy method not only increases the reliability of the identifying results but also provides a practical means of identification optimization.Application of this method in the analysis of petroleum products has shown its effectiveness.更多还原
