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
