多参数协同优化下新型模块化节点的承载性能研究

Jianzhu Gangjiegou Jinzhan
针对带中心区加强环的新型铝合金模块化节点承载性能优化问题，文中基于ABAQUS建立精细化有限元模型，系统性探究模块化单元厚度、加强环板厚、底部加劲板、螺栓布局等多参数的耦合影响规律。结果表明：将模块化单元底板厚度提升至顶板厚度的两倍，并增设10 mm厚底部加劲板，可使节点极限承载力最大提升11.98%，同时节点位移降幅达18.37%。通过对螺栓进行参数化分析，提出非对称优化配置方案，优化翼缘区与腹板区螺栓数量，既能改善节点受力分布，又可避免施工冗余。节点荷载-位移曲线显示，底部加劲板对刚度提升的贡献显著，

肠道菌群代谢物TMAO对兔动脉粥样硬化斑块形成及狭窄程度的影响 附视频

Zhongguo shiyan zhenduanxue
目的 探讨氧化三甲胺(Trimetlylamine oxide, TMAO)在兔动脉粥样硬化斑块产生及狭窄程度中的作用。方法 3月龄新西兰雄性白兔32只，随机分为对照组、模型组、TMAO组和TMAO抑制组，每组8只。对照组给予普通饲料喂养，余各组给予高脂饮食。喂养1周后，模型组给予高脂饮食+低温气体损伤兔颈动脉内膜建立动脉粥样硬化斑块模型；TMAO组操作同模型组，并给予氯化胆碱灌胃；TMAO抑制组操作同TMAO组，但饮水中加入TMAO抑制剂3,3-二甲基-1-丁醇(DMB)。术后12周再次检测血脂 ...
