摘　　要：文章给出了成长谱(GS)中的参量随风区、风时成长的计算式,其中由Toba的3/2次方定律引出了随有效波龄β_s变化的有效波陡的表达式。文章给出了CHGS方法中波高、周期随风时及风区的成长曲线,并与其他方法作了比较。文章还对波浪数值计算中风浪和涌浪的概念及其划分作了阐述。The calculation formulae of the parameters in the growth spectrum,which vary with the fetch and wind period, are given in this paper. Especially,one of them is the significant wave steepness expression δs = 0.093√2π√/βsvarying with the significant wave age βs,which is deduced from Toba's 3/2 order rule,and is practically valuable.The curve describing the wave height and period varying with fetch and wind period in CHGS method is given and compared with other methods.The concepts of wind wave and swell, and the division of them in the numerical calculation of ocean wave are explained as well.
