| 摘 要： | 本文用Taylor方法计算规则波中垂直圆柱二阶绕射力,发现该法对于水深与波数的乘积大于2.5时是有效的,其结果是精确的,但当水深与波数的乘积小于2.5时,结果是不稳定的。因此,须对方法作些改进。

| Abstract: | The method suggested by reference [1] is used to calculate second order diffraction force on a vertical cylinder in regular waves. It is found that the method is effective when the product of the water depth and the wave number is larger than 2.5 and that the result is instable when the product of water depth and the wave number is less than 2.5, In the latter case we must improve the method to obtain an approximative solution. |
