bulbous bow

Secondly, the Genetic Algorithms are introduced, and the position optimization and the dimension optimization of the bulbous bow are carried out in turn, and the optimal wave-making resistance coefficients are reached for different speeds and the form parameters of the bulbous bows are obtained.

然后通过引入遗传算法，先后进行了单体船的球首位置优化以及球首主尺度优化，得到各种速度下的最小兴波阻力系数，同时得到球首各形状参数。

the most obvious changes from the original titanic would be below the water line, including welding rather than rivets, a bulbous bow for greater fuel efficiency and enlarged rudder and bow thrusters for increased maneuverability, palmer said.

帕尔默说，泰坦尼克II号区别于泰坦尼克最大的地方就是在水位线下焊接了（不是铆接）球形艏门以提高燃料的工作效率，扩张船舵和船首推进器的尺寸，使其更便于操作控制。
