This paper gives a method to evaluate the quality of the impedance-matching experiments by the relation between standard and unknown materials shockwave velocities.
介绍了用标准材料与待测材料的冲击波速度的关系评价阻抗匹配实验质量的一种方法。

This method is used when the stone is large and not able to be removed by extracorporeal shockwave treatment.
这种方法时所用的石头是大和无法被删除体外冲击波治疗。
