In order to research the mechanism and effect of hydrodynamic cavitational enhancement, find the basic rule which affected it. The work has been carried out as following.First, an effective equipment of hydrodynamic cavitition is built. Second, we find a new method to capture the free radicals, which is used to measure the amount of hydroxyl. And its correlation with the intensity of cavitation has been studied aims at analyzing the effect of various factors on the yield of hydroxyl, achieving the optimum hydrodynamic cavitation conditions. Then, hydrodynamic cavitation is used to the degradation of organic wastewaters containing rhodamine B, and sterilization of biologic wastewaters containing enterobacter aerogenes. Finally, numerical simulation based on computer fluid dynamic has been made for verifying the effect of hydrodynamic cavitation theoretically.

In the second chapter, the stabilities of periodic regular gaits for six-legged robots walking longitudinally and laterally were systematically studied respectively, employing a hexpod's geometric model with outward extension of middle legs. Major progress and achievements reached are: a Both the necessary and the sufficient conditions for static walking of hexapods were established theoretically. b A generalized optimization method of gait stability was investigated. c For all feasible duty factor, stability-optimal gaits were obtained, with the expressions being of wide adaptation.
