2.2197合金在T6状态欠时效以δ′相强化为主，峰时效以少量δ′、θ′和T1相联合强化为主，虽然T1相的强化效果远远优于δ′、θ′相，但由于该合金不是主要以大量T1相强化为主，因而2197合金只具有中等强度。

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.

By non-enhancement scan, 12 cases showed low density mass, 4 cases equal density mass, 1 case slightly high density mass, and 2 cases stippled calcification mass. By enhancement scan, 13 cases showed inhomogenous enhancement in cortical phase, 2 cases showed slight to moderate enhancement. Another 2 cases of small cystic RCC presented enhancement of wall with nodules and the partition.
