The extend work of my doctoral research is introduced in the part. problems of cavitation noise are investigated with three methods such as theory analysis, numerical simulation and experiment research. mixed boundary element method is put forward to solve acoustics of bubble collapse by author
第二部分：空化噪聲研究該部分工作是作者博士期間工作的延續，對空化噪聲問題從理論分析方面、數值模擬及實驗三方面進行研究，應用作者提出的混合邊界元方法求解了空泡在邊界附近潰滅時的輻射噪聲問題。Due to its complexity of the problem, the theories and experiment results obtained are discrepant, and some of them are even contrary one another. started from the influence by movement rules of small cavities and solid particles, the mechanisms of combined effect of cavitation and sand abrasion are study in this thesis from the aspect of the turbulent coherent structure near the wall. first, a dynamic equation is established for a single spherical bubble and single spherical sand under the non - turbulent coherent structure near the wall, and then a dynamic equation established under the turbulent coherent structure near the wall
首先從理論上推導出在典型湍流邊界層模式的非擬序結構下空泡與固體顆粒的近壁區運動方程，然後推導出湍流近壁擬序結構作用下的空泡與固體顆粒的近壁區運動方程，再將兩種不同條件下的的運動方程進行比較，指出湍流近壁區的擬序結構對空蝕與磨損的發生具有決定性的意義，即正是由於擬序猝發作用的存在，才使得空泡、沙粒對壁面的空蝕與磨損作用得以發生。The effect of hydrogen on the ductility of electroless copper deposit is primarily caused by molecular hydrogen contained in voids, particularly the type gb voids
鍍層延展性降低的主要原因是由氫氣泡的缺陷效應，特別是第三類氫氣泡、晶粒邊界氣泡空穴。
