对非定常线性兴波问题的求解，第5章作为算法的验证，从较简单的近自由面运动潜体的非定常兴波问题入手，首先对无限水深近自由面潜体突然加速和渐近加速的非定常兴波问题作了计算，给出了非定常兴波波形和非定常兴波阻力随时间的变化曲线，计算结果与其它文献给出的结果进行了比较，其吻合程度令人满意。

Tsunami waves are long waves of gravity, the wavelength of up to 100 kilometers above; its velocity equal to the acceleration due to gravity (9.8 m / s) and the product of the square root of water depth, so the deeper the water, the faster the tsunami wave, the more shallow water , the slower the speed of tsunami waves.

海啸波是重力长波，波长可达100公里以上；它的传播速度等于重力加速度（9.8米／秒）与海水深度乘积的平方根，所以，海水越深，海啸波速度越快，海水越浅，海啸波速度越慢。
