He was stunned when he opened my heart, since the structure of my mitral valve was so particular that they may had never seen it, there was no chordae tendineae on the back lobe of mitral valve, my mitral valve shaped like a cloak, medically called " cone mitral valve", I thought they may basically had seen it on textbook.

The simulation results show that the asymmetry structure of the ratchet die cavity influences the BMG's flowing behavior greatly. During the material filling tooth cavity, dead zone volumes exist and situate on the areas with sparse teeth distribution. The full filling or not of the ratchet tooth tips, as the final filling region of the forming process, determines the super-plastic forming quality. Adopting smaller punch speed or longer load holding time is necessary for full filling of the tooth tips.

研究结果表明，棘轮模腔结构的不对称性对材料的流动行为影响显著；在材料向齿形的充填过程中存在流动死区，死区的位置处于齿形分布较稀疏的部位；齿形尖角是成形的最后充填部位，在终成形阶段采用较小的压下速度或较长的保压时间，有利于齿形尖角的完全充满。
