Carotid sinus pressure has little or no effect on the atrial rate in atrial flutter.
压迫颈动脉窦对心房扑动时的心房率几乎不起作用。

The effect of nonlinear structural stiffness on flutter velocity was considered, too.
同时，本文还考虑了结构刚度非线性对颤振速度的影响。

The panel flutter boundaries are finally determined and the effect of temperature, airflow speed, etc, on the panel flutter characteristics is analyzed.
