以牛顿第二运动定律的转动方程介释一枚大小为27mm的Carbomedic人工心脏瓣膜。在(?)升力和纯物体经验主义建立无用力时,由潜流原理建立了升力和纵向摆动力矩。浮力和重力的作用是在假设瓣叶均匀一致的前提下。另一假设包括均匀流动、枢轴的摩擦忽略不计和在对称的条件下,按1～10Hz顺序,从开启动态特性方面观察振荡。看到振荡频率 Explain a Carbomedic heart valve with a size of 27 mm using the rotation equation of Newton’s second law of motion. In the (?) Lift and pure object empiricism to establish uselessness, the lift and longitudinal oscillatory moments are established by the underflow principle. The effect of buoyancy and gravity is on the assumption that leaflets are uniform. Another hypothesis consists of a uniform flow with negligible friction at the pivot axis and observing oscillations in the symmetrical conditions in the order of 1 to 10 Hz from the opening dynamics.
