摘要：在“双碳”背景下,企业数字化和绿色化转型协同显得至关重要,它不仅有助于推动经济社会全面绿色转型,而且有利于促成企业实现可持续发展。本文首先通过运用熵值法和耦合协调度模型,对企业数字化与绿色化转型协同度进行测算。接着,基于2010—2021年1659家A股上市公司的面板数据,构建双向固定效应模型,探究企业数字化与绿色化转型协同对可持续发展绩效的影响作用与内在作用机制,以及地方“低碳”政策力度对上述关系的调节效应。研究发现:(1)企业数字化和绿色化转型协同是一种相辅相成、相互支撑与协作的战略协同关系;(2)企业数绿转型协同对可持续发展绩效具有显著的促进作用;(3)企业数绿转型协同通过提高资源配置效率,进而提升企业的可持续发展绩效;(4)我国地方低碳政策力度显著增强了企业数绿转型协同对可持续发展绩效的促进作用。本研究可为企业可持续发展以及地方政府关于低碳政策的设计及实施提供意见参考。

摘要：为了解决连铸高温、高噪声环境下钢包水口人工装卸劳动强度大、安全风险高、连铸钢包对接水口准确率低与效率低等问题,设计了以3D高精度视觉引导技术为检测系统,PLC设备为控制平台,六轴工业机器人为柔性驱动源的连铸钢包长水口装卸控制方案。该方案通过以太网通信将视觉系统检测到的位置信息经PLC控制传送至机器人系统,并按工艺要求驱动机器人完成自动化动作流程,实现连铸钢包长水口装卸流程动作的精确智慧控制。经测试结果证明,该技术实现了从机器人取工装开始到放回工装,整个安装或拆卸长水口时间≤80 s,装卸命中率>99%,满足了工艺要求和指标。此系统不仅使操作人员从重体力劳动和恶劣工作环境中解放出来,而且提高了装卸水口的准确性和稳定性,极大地提升了生产效率,保证了铸坯质量。

摘要：为了有效地提高钢空腹夹层板剪力键的传力效率,将传统的方钢管剪力键改为带翼缘的十字型剪力键,又称异形剪力键。对该结构设计5.3 m×1.3 m×(0.2+0.1)m的缩尺模型进行静力加载试验,采集挠度和应变等数据。介绍使用大型有限元(finite element,FE)软件ANSYS对该结构进行模拟的建模方式。将试验采集的数据与有限元计算结果进行对比,得到如下结论:试验与有限元结果吻合度较高,可以在接下来的研究中采用文中所述有限元建模方式进行进一步的研究;相较方钢管剪力键,异形剪力键的腹板与盖板协同传力,使得剪力键各部位受力更加合理、均匀,传力效率更高。

摘要：目的评估三维扫描技术在扩张皮瓣术前设计中的价值,通过此方法对病人二期扩张皮瓣转移手术时机进行客观和准确地判断,避免扩张皮瓣面积不足或过量。方法2024年4月~2024年9月收治的拟计划接受局部扩张皮瓣修复病人10例,借助Vectra WB360三维成像仪对病人的创面缺损面积、扩张器底座面积及扩张皮面积进行测算,并与术中结果进行比较,评估此技术用于指导扩张皮瓣手术的准确性。结果10例病人采用Vectra WB360三维成像仪测量扩张器表面积(扩张皮面积)、扩张器底座面积、病灶面积分别为(539.3±268.4)cm^(2)、(157.0±78.13)cm^(2)、(252.8±141.6)cm^(2),术中实际测量分别为(470.7±230.4)cm^(2)、(159.9±83.2)cm^(2)、(241.7±134.1)cm^(2),其中仪器测量的扩张器底座面积、病灶面积与术中实际测量的相比,差异均无统计学意义(P>0.05),仪器测量的扩张皮面积大于术中皮瓣面积,差异有统计学意义(P<0.05),与扩张器取出后扩张皮回缩有关。术中皮瓣均可完整覆盖创面,术后皮瓣全部存活,1~6个月的随访显示,术区外形和功能恢复良好,病人满意度高。结论Vectra WB360三维成像仪能显著提高术前皮瓣面积估算的准确性,优化手术计划,提高扩张皮瓣手术的成功率。

摘要：以利用视错觉改善服装与人体结合呈现效果为目的,在多种色相条件下,对色彩饱和度高低与明度高低进行分组实验,测量消费者在不同条件下的唤醒、注意力、身材感知和购买意愿。采用方差分析、回归分析讨论色彩饱和度、明度分别对身材感知的影响以及唤醒、注意力在其中的中介作用。研究结果表明:高色彩饱和度服装比低饱和度服装的穿着效果更显胖,高明度比低明度的服装穿着效果更显胖,但前两种效应对消费者购买意愿影响差异均不显著;唤醒和注意力在饱和度对身材感知影响中起中介作用,具体表现为高色彩饱和度会引起高唤醒水平,吸引更多注意力,从而影响身材感知更胖,但这种中介作用仅仅在纯色服装中显著,而在条纹服装中不显著。
