• In general , the upward amplitude curve " curvature is larger , and it changes quicker . on the contrary , the downward is smaller and slower ; because the flare force contains the square of the wave elevation velocity , it results in an difference between the flare force frequence and the associated moving frequence ; the flare force decreases the downward amplitude of heaving oscillations ; the speed of ship has an ignorant effect on the peak values of three calculated values , but there is an obvious effect on the oscillating frequence ; the wave amplitude has an effect on the ship motion , and there is an linear relation between the oscillating amplitude and the wave amplitude on the whole . by the way , there are some experiences and lessons according to the progress calculation : before the calculation of the ship motion , we should checkout the balance in a calm water firstly , namely , the whole displace of ship and the longitudinal position of the center of gravity must be consistent with the draft in calm water , or else , the calculation may show the " floating " phenomenon ; the mixed language programming has a lot of virtues , but it exists a fatal limitation - the debug of dll
  研究表明：在某些频率范围内相关水动力系数基本不随吃水变化，只有超过某一频率后水动力系数的值才会出现差异；在横摇方向，水动力系数并没有随着吃水的变化发生规则变化，而是出现了波动现象；近船首剖面的水动力系数计算表明，水动力系数的波动非常大，并远远偏离了平均位置的水动力系数值，值的变化速率也不尽相同，总的看来，上振幅曲线曲率较大，变化较快，下振幅曲线曲率较小，变化较慢；外飘力和波面运动的速度的平方项有关，导致其振动频率和相应运动方向的频率不同；外飘力使升沉向下运动的幅值减小；船速对三个计算量的峰值影响甚微，但对振动频率有明显影响；波幅对船舶运动的影响是明显的，船舶运动的幅值基本上和波幅成线性关系。
