1.Objective To investigate the best postures of patients with cystolithiasis for extracorporeal shock wave lithotripsy(ESWL) treatment.

1.目的探讨体外冲击波碎石术(ESWL)治疗膀胱石的较佳体位。

2.According to the syntaxis skill of shock wave and the theory of effective charge,the annular conical booster pellet structure is designed.

2.根据冲击波汇聚技术原理及有效理论,设计出环锥构。

3.Experiments on influence of shock wave with some strength on components of blood were conducted in a diaphragmless shock tube developed in our laboratory.

3.用自行研制的无膜激波管，研究在一定强度激波的作用下，激波对血液成分的影响。

4.Most of the work was based on experiment results, and some empirical formulas of shock wave peak pressure, electroacoustical efficiency, and plasma parameters were obtained.

4.这些机理的获得绝大部分基于实验果，如已经获得了一些冲击波峰值压力的经验公式，电声学效率，以及等离子体参数。
