An increase in extracellular potassium does in fact shift the pacemaker within the sinus node from the cephalic to the caudal portion . 细胞外液钾的增高确实能使窦房结内的起博点从头侧移向尾侧。
With the diaphragms assumed rigid in their own planes, all the frames sway by the same amount at a given floor level . 假设各楼板在它们自身平面内为刚性者,在每一给定楼板水平面处所有的框架产生相同的侧移。
Second - order elastic analysis of sway frames 有侧移框架二阶效应的弹性分析
For the whole structure its controlling effect is secondary 对于结构而言,其侧移起辅助控制作用。
Lateral displacement stiffness of structure 结构侧移刚度20
Lateral displacement stiffness of storey 楼层侧移刚度20
Effective length factor of columns in sway and semi - rigid composite frames 有侧移半刚性连接组合框架柱的有效长度系数
Frame without sidesway 无侧移框架12
Frame with sidesway 有侧移框架12
Lateral displacement analysis is one of the most important items for steel frame design 侧移分析是钢框架结构分析的重要内容之一。
