Ultrasonic properties of kidney stones were studied with a double-probe-through-transmission technique, the micro hardness was studied using the Viker indentation method and the chemical composition studied using an X-ray technique. The microhardness is found to vary with chemical composition as well as ultrasonic propagation velocity. The comparative results obtained are discussed in detail.
采用双探头穿透传输技术研究肾结石的超声特性，使用维氏压痕法研究其显微硬度，并采用X射线技术研究其化学成分。发现显微硬度随化学成分以及超声传播速度而变化。对所获得的比较结果进行了详细讨论。
