广义判断下AHP(GJAHP)的一致性检验与可接受性的进一步探讨

广义判断下的AHP(GJAHP)是在单准则下通过构造广义判断矩阵的数学模型而建立的一种广义AHP.本文提出了广义判断矩阵一致性的一种非参数统计检验方法--spearman秩相关系数法, 给出了广义辅助矩阵的构造性定义, 并进一步探讨了广义判断矩阵的可接受性。最后本文给出了GJAHP的应用实例。     

湿地松对松针褐斑病的抗性测定

从松针褐斑病（Ｌｅｃａｎｏｓｔｉｃｔａ ａｃｉｃｏｌａ）重病林分中选出３６个湿地松（Ｐｉｎｕｓ ｅｌｌｉｏｔｔｉｉ）抗病表现型优树无性系，用人工喷洒病菌孢子液接种法对其进行抗病测定，结果表明，有２２个是高度抗病的。与用松针褐斑病产生的毒素粗提液处理上述无性系的离体针叶进行抗病性测定的结果基本一致，相关系数为０．８０。

SIMULTANEOUS REACTION AND LIQUID-LIQUID EXTRACTION IN THE HYDROGEN PEROXIDE PRODUCTION

The gas-liquid-liquid reactive extraction system for preparing hydrogen peroxide via anthraquinone was investigated. The oxidation reaction of hydrogenated working solution was combined with the extraction of hydrogen peroxide from working solution in a sieve plate column. The reaction of 2-ethylanthrahydroquionone with oxygen and the liquid-liquid extraction of hydrogen peroxide take place simultaneously. The oxygen was introduced with hydrogenated working solution through a nozzle in the bottom of the column, which worked as agitated air as well as oxidation reagent. The results showed the oxidation and extraction do not hamper each other, on the contrary, the presence of oxidation gas in the column can promote the transfer of hydrogen peroxide from organic phase to aqueous phase, thus the reaction efficiency and extraction efficiency increased with increasing gas superficial velocity. Furthermore, the oxidation efficiency is almost 100% and the extraction efficiency is higher than 90% in this process.
