rotary motion

基本解釋

With the right configuration of muscles it is even possible to produce rotary motion.
只要配置得當(dāng)，它甚至還能產(chǎn)生旋轉(zhuǎn)運動。
That was useful for pumping, but limited the engine’s application to things that require a rotary motion—grinding, for example.
這適用于抽水的水泵，卻不能運用于諸如研磨機(jī)這類其他需要旋轉(zhuǎn)移動的機(jī)器，限制了蒸汽機(jī)的應(yīng)用。
With the possible exception of the propeller-like flagella of bacteria, there are no examples of organisms that use muscles to create continuous rotary motion.
也許細(xì)菌那像螺旋槳似的鞭毛是個例外，但其他有機(jī)體是無法用肌肉產(chǎn)生持續(xù)不斷的旋轉(zhuǎn)運動的。
