碎石技术中利用声冲击波粉碎生物矿质结石是生物医学中一大研究课题。这里使用的是上升时间为0.3μs、能量300J、峰值压力300MPa的指数式声冲击波。结石成分由红外分光技术分析。在初期。结石分裂具有这样的特点,即由于介质界面机械应力的作用。使得结石表面分离出碎粒。对于每一个声冲击波,碎粒分离的情况如下:0.1—1mm的碎粒(称为第4部分),占总重量的3—5.3％;1—2mm的碎粒(第3部分),占1.3—5.2％;2—4mm的碎粒(第2部分),占0.6—1.7％;更大的碎粒(第1部分),没有发现。3个声冲击波作用后,小于1mm的碎粒重量只占3％;
The use of acoustic shock waves to crush bio-mineral stones in gravel technology is a major research topic in biomedicine. Here are the exponential acoustic shock waves with a rise time of 0.3 μs, an energy of 300 J and a peak pressure of 300 MPa. Stone composition by infrared spectroscopy. In the early. Stones split has the characteristic that due to the mechanical interface effect of the media interface. Making stone surface separation of nibs. For each acoustic shock wave, the particle separation is as follows: 0.1-1 mm of nibble (referred to as Part 4), 3-5.3% of the total weight; 1-2 mm of nibs (Part 3), 1.3 -5.2%; 2-4mm nibs (Part 2), 0.6-1.7%; larger nibs (Part 1), not found. After 3 acoustic shock waves, the weight of the pieces less than 1mm accounted for only 3%.
