Comparing the highest and lowest quartiles of carotid intima - media thickness, the researchers found that the relatie risk of atrial fibrillation, after adjusting for all potential confounding factors, was 1. 90 oerall, which broke down to 1. 61 in men and 2. 14 in women
比較頸動脈內中膜厚度的最大和最小的四分位數，學者發現針對所有潛在的混雜致病因素進行調整后，房顫的相對風險總的來說為1 . 90 ，分為1 . 61 （男性）和2 . 14 （女性） 。In addition, aerodynamic stiffness and aerodynamic damping on the system are already obtained in the condition of fluid - structure interaction. it is known that aerodynamic loads are associated with blade vibration. the systematic eigenvalues are used to judge whether the flutter occurs so as to find the stable operating range of a wind turbine
本文把風力機葉片簡化為懸臂梁，對梁截面的二維葉型建模，完整推導了二維葉型的線性運動微分方程和流構耦合條件下系統的氣動剛度和氣動阻尼，此時氣動載荷與結構的位移矢量以及速度矢量是相互耦合的，再利用系統的特徵值來判斷葉片顫振是否發生，從而獲得風機的穩定工作范圍。
