From the results obtained in the study, the following conclusions can be made:The methylene blue and spectrophotometer method can capture the free radicals generated successfully. This is an effective way to measuring the free radicals quantitatively in cavitation, moreover it is easy to fulfill.The intensity of cavitation increases with reduction in the cavitation number. But the different mechanism of various enhancive processes (chemical and physical processes) results in different effect by cavitation number.The effect of operating parameters, such as inlet pressure, temperature and time on cavitation indicate that optimum operating conditions exist at the cavitation enhancive effect is maximum.It is important to optimize the structure of hydrodynamic cavitation reactor for achieving a desired effect. A reasonable geometric parameter can promote the enhancive effect for a fixed hydrodynamic condition.Ventilating appropriate gas to cavitating flow can increase cavitational intensity and hence promote the enhancive effect of hydrodynamic cavitation.

研究结果表明：亚甲基蓝分光光度计法，能够成功地捕捉到水力空化产生的羟自由基，是定量检测空化自由基简便易行的有效方法；空化程度随空化数的减小而增强，但对于不同的强化过程，因其强化机理不同，故空化数对强化效应的影响也不同；水力空化系统的压力、温度及时间等操作参数对空化强化效应的影响规律表明：在适宜的操作条件下可产生最佳的空化强化效果；空化发生器结构的优化设计是保证空化强化效应的重要前提，在一定的水力学条件下，合理的结构尺寸可以增强空化作用效果：往水流中适量加入干扰气体能够提高空化强度，增强空化强化效果。

Nine years did I stay with them, and many beautiful works in bronze, brooches, spiral armlets, cups, and chains, did I make for them in their cave, with the roaring waters of Oceanus foaming as they rushed ever past it; and no one knew, neither of gods nor men, save only Thetis and Eurynome who took care of me.

作为工匠，我在她们那里生活了九年，制铸了许多精美的用品；有典雅的胸针、项链、弯卷的别针和带螺纹的手镯，在空旷的洞穴里，四周是俄开阿诺斯奔腾不息的水流，泡沫翻涌，发出沉闷的吼声。除了欧鲁诺墨和塞提丝――因为她俩救了我――此事神人不知，谁也不曾悉晓。
