大学生体育锻炼与社会公平感之间的关系：感知到的社会支持和生活满意度的链条介导的作用
结果：（1）在体育锻炼和社会公平感之间发现正相关（r = 0.151，p <0.01）。还观察到了体育锻炼对社会公平感的显着直接影响（β= 0.151，t = 3.971，p <0.01）。（2）体育锻炼是感知社会支持的积极预测指标（β= 0.113，t = 4.062，p <0.01），进而对生命满意度产生了积极影响（β= 0.333，t = 18.047，p <0.01）和社交意义（β= 0.485，t = 0.485，t = 6.9331，p <0.485，p <0.011，p <0.01，p <0.01，p <0.01。此外，生活满意度对社会公平感有积极影响（β= 0.431，t = 3.247，p <0.01）。（3）感知到的社会支持和生活满意度都通过两种途径显着介导了体育锻炼和社会公平感之间的关系：体育锻炼→感知的社会支持→社会公平意识（调解效果：0.055）；和体育锻炼→感知的社会支持→生活满意度→社会公平感（调解效果：0.016）。

供应链是参与供应原材料、生产产品并将其交付给最终用户的公司组成的物理网络。供应链管理是一系列相互关联的活动和决策，旨在有效地整合供应商、制造商、仓库、运输服务、零售商和消费者。本研究的目的是确定Jeky PM供应链管理的绩效。本研究采用定性方法，重点评估供应链管理绩效。杰基PM鸡肉供应链，从农户作为活鸡的供应商开始，下一条链条就是杰基PM作为鸡肉的供应商，这条链条上有从农户的活鸡加工成鸡肉，再分销给代理商和批发商以及直接销售给周边社区的生产环节，经过主链条之后，有5条链条是杰基PM的分销渠道，分别是：周边社区，批发商，超市，酒店和餐馆。五条链条中，有三条最终链条，即当地社区、传统市场和超市的买家、以及烹饪鉴赏家。 Jeky PM的领导层应该建一个仓库来储存鸡，以尽量减少鸡肉分配的延误。

链条附件已使用多年，具有多种配置和应用，但是，附件不能从一个制造商的链条互换到另一个制造商的链条，从而限制了用户只能使用一个供应源。人们审查了尺寸和公差标准化的必要性，以实现滚子链附件的互换性，并于 1947 年成立了该协会滚子链技术委员会的一个小组委员会，以提出实现互换性的标准。这项工作的结果已由分部委员会 229 审查和批准。

第 10 讲：重力、功和能量守恒
力方向上的距离。示例：两匹马拉着一辆临时雪橇上的一名男子。男子和雪橇的总质量为 204 公斤，雪橇和地面之间的摩擦力为 700 N。当马拉雪橇时，三条链条中的每一条都具有 396 N 的张力，并且相对于水平方向成 30.0° 的角度，它们将男子拉动了 20.2 米的距离。确定 A) 其中一条链条对雪橇所做的功，B) 其中一条链条对马所做的功，以及 C) 摩擦对雪橇所做的功。
