New generation thermo-mechanical control process(TMCP) based on ultra-fast cooling is being widely adopted in plate mill to product high-performance steel material at low cost. Ultra-fast cooling system is complex because of optimizing the temperature control error generated by heat transfer mathematical model and process parameters. In order to simplify the system and improve the temperature control precision in ultra-fast cooling process, several existing models of case-based reasoning(CBR) model are reviewed. Combining with ultra-fast cooling process, a developed R5 CBR model is proposed, which mainly improves the case representation, similarity relation and retrieval module. Certainty factor is defined in semantics memory unit of plate case which provides not only internal data reliability but also product performance reliability. Similarity relation is improved by defined power index similarity membership function. Retrieval process is simplified and retrieval efficiency is improved apparently by windmill retrieval algorithm. The proposed CBR model is used for predicting the case of cooling strategy and its capability is superior to traditional process model. In order to perform comprehensive investigations on ultra-fast cooling process, different steel plates are considered for the experiment. The validation experiment and industrial production of proposed CBR model are carried out, which demonstrated that finish cooling temperature(FCT) error is controlled within ±25 ℃ and quality rate of product is more than 97%. The proposed CBR model can simplify ultra-fast cooling system and give quality performance for steel product.

目的 修订中文版亲密关系冲突应对方式量表并检验其在中国群体中的信效度.方法 通过翻译和回译以及专家评审和预实验的方法形成原始的中文量表,对223名中国已婚被试进行测量,完成量表的条目筛选和探索性因素分析,确定正式的中文量表.然后在454名中国已婚被试中施测以检验中文量表的信效度.对其中78名被试在1个月后再次施测,考察重测信度.结果 探索性因素分析表明,中文版亲密关系冲突应对方式量表由7个因子构成,可解释的总变异率为60.887%,与原版量表的6因子结构存在差异.经过验证性因素分析发现中文量表的6因子模型比7因子模型拟合的更好,并结合专家意见最终确定中文版量表包含妥协、控制、顺从、分离、回避和行为反应共6个因子,30个条目.各因子 x的Cronbach'sα系数、分半信度系数和重测信度系数分别为0.604~0.872、0.613 ~0.808、0.611 ~0.672,均达到统计学意义.结论 中文版亲密关系冲突应对方式量表具有较好的信、效度,可以用于评估中国夫妻的冲突应对行为.

针对结构相似度(SSIM)模型不能对模糊和高纹理图像进行较好的质量评价,提出一种基于相位一致结构相似度(MPCSSIM)的全参考图像质量评价方法.该方法保留SSIM中的亮度函数和对比度函数,将结构函数替换成相位一致函数,然后将三者结合起来进行质量评价.实验中LIVE数据库上的计算结果与主观评分的线性相关系数和斯皮尔曼相关系数分别为0.9501和0.9362.实验结果表明相位一致能够更好地提取图像的结构信息,该方法有较好的性能,能够更准确地评价模糊图像和高纹理图像的质量.
