海豚是海兽中的游泳冠军,速度可达70千米小时,当它受到惊扰或追捕其他海中动物时,速度可达100千米小时,比普通快艇要快得多。现在,越来越多的科学家对海豚产生了浓厚兴趣。这些飞梭般出没于海中的海豚,游泳时毫不费力,好像水的阻力对它们不起作用似的。然而,根据流体力学专家的计算,海脉的游动速度似乎不可能超过20千米小时,而且早在1936年,英国科学家格雷就发现,海豚的游速已超出了它的肌肉力
The dolphins are swimming champions in the beasts, which can reach speeds of up to 70 km. When they are disturbed or hunt down other animals in the sea, the speed can reach 100 km. This is much faster than ordinary speedboats. More and more scientists are now interested in dolphins. These shuttle-like dolphins are found in the sea. They swim effortlessly, as if the resistance of water does not work for them. However, according to calculations by fluid mechanics experts, it seems unlikely that the velocity of the sea pulse will exceed 20 km. And as early as 1936, British scientist Gray discovered that the speed of the dolphins has exceeded its muscle strength.
