个体社会责任品质的培育应合乎现代人的身心发展规律并与社会发展的规律相统一,其培育目标应以马克思主义人学理论为基础,突出人的现实性、社会性和全面性,主要从内容维度和过程维度进行建构。内容维度的总体目标应包括秩序理性、社会关怀、社会担当、社会参与四个方面,即通过秩序理性强化社会责任认知,通过社会关怀培育社会责任情感,通过社会担当磨炼社会责任意志,通过社会参与引导社会责任行为。从过程维度考察,起步阶段的目标在于培育个体的是非品质,深化阶段的目标是培育个体的合群品质,成熟阶段的目标重在使个体养成利他主义的品质。

以粗轧轧辊孔型为优化对象,对影响折皱缺陷的因素进行了分析,提出了一种基于随机森林的粗轧过程孔型参数优化设计方法。首先,采用DEFORM-3D软件建立三维轧制热力耦合有限元模型,分析了折皱缺陷的产生原因,探究了折皱缺陷的影响参数;然后,开发了基于随机森林算法的机器学习模型,建立了变形温度、孔型圆角尺寸、槽底宽度和轧辊与轧件间的摩擦因数与宽展值之间关系的设计数据库;结合约束条件,得到了孔型参数的最优解,最后,对优化后的孔型进行了验证。研究结果表明:当孔型槽底宽度b k为165 mm、圆角尺寸R为14 mm时,取得最优解,此时宽展值最小;采用优化后孔型进行生产,消除了折皱缺陷,成品合格率明显提高。

Palladium nanoparticles(Pd NPs) were fabricated by using insulin amyloid fibrils(INSAFs) as *** force microscopy measurements showed that ultrasmall Pd NPs were well adsorbed and dispersed on surfaces of INSAFs. X-ray photoelectron spectroscopy confirmed the partial reduction of Pd ion into metallic Pd(0) probably due to the presence of Cys groups on surface of the insulin fibrils. The electrochemical performance of Pd/INSAFs to reduction of H_2O_2 was further evaluated by cyclic voltammetry. The remarkably high electrocatalytic activity, low detection limitation and excellent stability make the Pd/INSAFs a promising bio-nanoelectrocatalyst.
