西德研究把高能冲击波导入人体内,使冲击波在反跳到肾结石时将结石粉碎。冲击波通过均匀介质的速度比声音快,基本上与声波有相同的传播规律。这种冲击波遇到人体不同声阻抗时,就会产生部分反射。在结石的前面出现冲击波,在背面产生张力波,被用来粉碎结石(见图1),这已得到实验证明。通过使水池中的水下火花隙放电 West German research into high-energy shock wave into the body, the shock wave in the anti-jump to the kidney stones will be crushed stone. Shock wave through the uniform medium faster than the sound speed, basically the same with the sound wave propagation. This shock waves encounter the body’s different acoustic impedance, it will have some reflections. Shock waves appear in front of the stones, and tension waves are generated on the back, which are used to crush stones (see Figure 1). This has been experimentally demonstrated. By discharging the underwater spark gap in the pool
