Shuitu Baochi Xuebao, 2002 将高维降维技术--投影寻踪分类模型(PPC)应用到土壤学科领域,利用改进的加速遗传算法(RAGA)优化投影方向(土壤评价指标),将多维数据指标转换到低维子空间,通过寻求最优投影方向及投影函数值来实现对土壤的分类与等级评价,避免了主观赋权的人为干扰,取得了较好效果,为土壤质量变化与等级评价研究提供一条新思路与方法.

Dianci bileiqi, 1985 本文提出以产量——平均产量、比产量、输送效率和产量波动,能耗——功率和单耗,机重——机器重量和单重等主要技术经济指标作为评价真空练泥机的主要内容之一;并以ZLN-350和ZLN-500真空练泥机为实例作了比较评价。提出以泥料陶瓷物理性能均匀性指标,挤制泥料温升,真空度和泥料中的空气含量以及结构批陷等评价真空练泥机的质量。

Zhongguo shiyan zhenduanxue, 2006 目的对室间质量评价的得分情况进行统计学分析,总结室内质控和室间质量评价的经验,以便更好地为临床服务。方法用全自动生化分析仪检测盲样19项临床生化指标。结果六年中质控检测19项指标,变异指数得分（VIS）A级占83.19%,B级占13.14%,C级占3.67%。1999年-2004年Na VIS得分A级从50%提高到60%,ClVIS得分A级从40%-88%。结论经过改进使过去结果不太准确的指标得到修正,质量控制对于临床生化检验结果的质量保证非常重要,只有做好室内质控和室间质量评价 ...
