nonrestrictive

In this paper matlab and vb are used to build a software which can predict absorption coefficient ' s of the underwater anechoic coatings from these analytical models . finally , some algorithm of the single parameter minimization , nonrestraint nonlinear minimization and restraint minimization in the optimization design theory are studied . the formulas of absorption coefficient of these analytical models are object functions 本論文利用各種解析模型的聲學設計理論,使用matlab與vb軟件建立了一套水下消聲覆蓋層吸聲系數預報軟件,研究了最優化設計中單參數最小化、無約束非線性最小化和有約束最小化理論的一些算法,利用現有模型的吸聲系數計算公式作為目標函數,初步優化了一些結構的材料參數。
