    Abstract: 在理想流體及低航述的假定下,將浮體在任意方向的波與流作用下之運動方程式予以簡
    化。簡化後之新的運動方程式的基本解可以格林函數之形式被表示為G:::::G0 + G1 ; 其中
    G0是一震盪源,為零航速情況的基本解;G1 相當于航遠的存在而出現的修正項。最後利用
    Under the assumptions of potential theory and low moving speed, the equations of a body advancing in waves are simplified. A form of the Green function for the simplified equations is expressed as G.apprxeq.G/sub 0/+.tau.G/sub 1/. It consists of Green function of an oscillating source at zero forward speed, G/sub 0/, and a correction term for low forward speed, G/sub 1/. It has been found that this form has good numerical performance. To test the present method it is applied to a hemisphere. The numerical results of the present method will be compared with the analytical solutions. The approach may offer a decent method in obtaining body responses due to low moving speed while wave damping effects are considered.
