摘　　要：应用无因次多项式表示理论风浪频谱可在相当大的范围内灵活选甩各项指数。文中绘出的各项系数可使频谱表达式满足:谱峰位于给定点S(1)=P;谱面积m_o=1;分段点w_1处谱值及斜率均连续。Non-dimensional multinomal is applied to theoretical wind-wave frequency spectrum, which produces much flexibility in choosing exponential for each term in the expression. The coefficient of each item in the spectrum is determined under the condition 1) the spectral peak is corresponding to a specified point where S(1)=P; 2) spectral area m0 = l and 3) spectral value and gradient continue at piecewise point w1.
