Objective To discuss the clinical result of A-V impulsepump application in the treatment of intra-articular calcaneal fracture.
目的探讨动静脉泵在跟骨关节内骨折围手术期应用的临床意义。
2
The impulse motion and the unbalanced vibration of the pump generate certain structural noise which could be significantly expressed in frequency spectrum.
泵的脉动运动与不平衡振动产生了结构噪声，结构噪声在频谱中清晰显示出来。

By adopting the technical proposal, the rotor pump can effectively reduce discharge impulse with low cost and simple structure.
