为了分析轮对蛇行运动的形成机理与能量传递机制,基于车辆系统动力学理论推导了轮对蛇行运动的能量表达式;借助轮对运动参数的相位关系和能量表达式,确定了轮对蛇行运动过程中各部分所做的功及其对应的能量传递路线;通过数值仿真计算不同参数条件下的输入能量,对比了踏面等效锥度、轮对质量、一系悬挂刚度与重力刚度等参数对轮对稳定性的影响规律。研究结果表明:蠕滑力和锥形踏面的协同作用是轮对产生蛇行运动的根本原因,蠕滑力中的刚度项通过调节纵、横向蠕滑率向轮对系统横向运动输入能量,蠕滑力中的阻尼项耗散轮对系统的能量;当输入能量大于耗散能量时,轮对蛇行运动发散,当输入能量小于耗散能量时,蛇行运动收敛,当输入能量等于耗散能量时,轮对做等幅周期运动;增大轮对质量和车轮踏面等效锥度不利于轮对的稳定性,增大一系悬挂纵、横向刚度对轮对稳定性有利;踏面等效锥度对轮对稳定性的影响最大,当锥度由0.15增大到0.20时,输入能量增大了约9.5倍;一系悬挂刚度的影响次之,刚度由75kN·m^(-1)增大到100kN·m^(-1)时,输入能量减小了约60%;轮对质量影响最小,轮对质量由1 000kg增大到2 100kg时,输入能量增长了约1.1倍;在锥形踏面下,重力刚度对轮对稳定性的影响可以忽略。

Enteromorpha prolifera polysaccharide-Fe(Ⅲ) complex promotes intestinal development as a new iron supplement

Science China Life Sciences 2025年第1期 219-231页

Iron is a crucial micronutrient, and its deficiency can have detrimental effects on the health of infants. Dietary polysaccharide-iron(Ⅲ) complexes(PICs) are promising for addressing iron deficiency due to their minimal adverse reactions and high iron absorption rate. This study aimed to investigate the effects of dietary Enteromorpha prolifera polysaccharide-Fe(Ⅲ) complex(EP-Fe) on newborns, using 3-day weaned piglets as the iron-deficiency model. Results showed that EP-Fe improved iron levels and promoted intestinal development in piglets. Transcriptome sequencing revealed that EP-Fe increased the survival of intestinal epithelial cells under hypoxia by upregulating the expression of genes that promote the development of the vascular system. Additionally, EP-Fe enhanced the mucosal barrier functions by inhibiting myosin light chain kinase(MLCK)/phosphorylated myosin light chain(p-MLC) signaling pathway to increase the expression of intestinal tight junction proteins. Furthermore, the 16S r RNA gene sequencing of gut microbiota showed that EP-Fe promoted the enrichment of Bacteroides＿fragilis and other gut microbes that can metabolize carbohydrates. In conclusion, EP-Fe is an effective iron supplement for newborns, and it can be developed as a comprehensive nutritional supplement.

《孙子兵法》与《战争论》被誉为东西方军事史上的两颗明珠。《战争论》以其"绝对战争"理论曾长期引领西方乃至世界的军事学,但在第二次世界大战后,特别是当"绝对战争"遇到"绝对武器"(核武器),敌我双方都拥有相互确保摧毁能力的情况下,人类将面临同归于尽的选择之时,孙子的"全胜"战略追求便成为战争问题上的济世良方。克劳塞维茨的理想战略是"百战百胜",属于军事层面的制胜观;而孙子追求的则是"不战而屈人之兵"的全胜战略,是大战略层面的价值观。两者最根本的区别是哲学上的区别,道胜是《孙子兵法》的哲学,器胜是《战争论》的哲学。
