  3. The formulation for the error analysis of acoustic radiation problem calculated by the boundary point method ( bpm ) is put forward ; the physical explanation of the boundary point analysis of the acoustic radiation problem is given ; the influence of the particular solution on the calculation stability of the bpm is studied ; the etthanced volume source boundary point method ( evsbpm ) is presented ; a test for the effectiveness of the evsbpm is carried out on the aspects of its calculation precision, calculation speed, calculation stability, adaptation to the geometric shape of vibrating body as well as its ability to overcome the non - uniqueness problem through various examples with different boundary shapes and different boundary value distributions

    第三章導出了邊界點方法分析振動聲輻射問題的誤差估計理論公式，揭示了邊界點方法分析振動聲輻射問題的物理本質；研究了特解場的局部特性對邊界點方法的數值穩定性的影響；改進了現有的特解場構造方法，提出了改進體積源邊界點方法；通過諸多不同邊界曲面和不同邊界量分佈的聲輻射算例，從計算精度、計算速度、計算穩定性、對振動體表面幾何形狀的適應性以及克服解的非唯一性等方面，對改進體積源邊界點方法的有效性進行了考證。
