1.如果流过蓝鲸或长须鲸身体的水流没有湍流,每磅所需的马力。运动肌的收缩率大约是格雷(1936)对鼠海豚和海豚的估计值的十分之一。2.如果这些大鲸的水流是湍流的话,每磅所需的马力。的肌肉同意密切与Gray9的估计较小的鲸类,或其他类型的哺乳动物的肌肉已被调查。
1. If the flow of water over the body of a Blue or a Fin whale be free from turbulence, the horse-power required per lb. of locomotory muscle is of the order of a tenth of the value estimated by Gray (1936) for the porpoise and dolphin. 2. If the flow be turbulent in these large whales the horse-power required per lb. of muscle agrees closely with Gray9s estimate for the smaller Cetacea, or for the other types of mammalian muscle that have been investigated.
