<International Circulation>:Peoples anatomy is similar enough that you end up with errors that small， but is this the anatomy of their hearts or of their vascular? 
  《国际循环》：人体解剖如此相似所以您能将误差降至很低，请问这种解剖学上的差异在心脏和血管上也很小吗？
    Prof. Alvolio :Essentially the brachial artery system， the arteries is the one place or case where that type of model does not work. For example， if you have an obstruction of the subclavian arteries are obstructed then that doesn’t work because you are then measuring something else. Thankfully that sort obstruction doesn’t happen too often in people – people’s arms don’t fall off and so on and so forth… But it does happen， and when it does happen it can’t be used.
    Alvolio教授：实际上上臂的动脉系统中的动脉血管是那种模型使用无效的地方。比如，如果你的锁骨下动脉有阻塞，这时使用那种模型就没用，因为这时测量得到的是其它的数值。庆幸的是这种阻塞并不是经常发生——人们的上臂并不是向下再向外……但是这种情况还是时有发生，并且一旦发生这种模型就不能被应用。
