This is how the electric motor transforms electrical energy into mechanical energy.

这就是电动机将电化机械过程。

That vibration converts sound energy to mechanical energy, which muffles the echo that gets back to the bats.

这种振动将超声波化机械，从而减弱了传回蝙蝠回声。

" Power, " finally, can mean energy, especially electrical or mechanical energy.

最后，“功率”可以表，尤其是电或机械。

The ball mill's mechanical energy turns the plastic into a fine powder.

球磨机机械将塑料变成细粉。

DNA, bone, and silk all have this ability to turn mechanical energy into electrical.

DNA、骨头和丝绸都具有将机械化电力。

Both of these results, turning mechanical energy into electrical, and electrical energy into mechanical, were remarkable.

这两个结果，将机械化电，将电化机械，都是非常了不起。

For the opposite transformation, converting mechanical energy to electrical, consider the lights that turn on when you clap.

对于相换，将机械换电，请考虑在您拍手时打开灯。

That vibration converts sound energy to mechanical energy, which muffles the echo that gets back to the bats.

霍普金：这种振动将声化机械，从而抑制了传回蝙蝠回声。

The competition will not require the machines to produce electrical power. He says changing the mechanical kinetic energy into electrical energy is easy.

这场竞赛不需要机器来制造电力，他说将机械动化电很简单。

And piezoelectric devices may become even more common since electricity is in high demand and mechanical energy is abundant.

由于电力需求大且机械丰富，压电设备可会变得更加普遍。

Motors take electrical energy – so, the current running through a coil of wire – and convert it into mechanical energy as the motor turns.

电机吸收电——即流过线圈电流——并在电机动时将其换机械。

The amazing thing about your complicated, self-healing, blood-guzzling muscle tissues is that they turn chemical potential energy into mechanical energy, or movement, simply by doing two things — contracting and relaxing.

你复杂，自愈，耗血肌肉组织神奇之处在于它们将化学势化机械，或运动，仅仅通过做两件事情——收缩和放松。

He wished to be shown that changes in form caused evolution in force; that chemical or mechanical energy had by natural selection and minute changes, under uniform conditions, converted itself into thought.

他希望证明形式变化会导致力进化。化学或机械通过自然选择和微小变化，在相同条件下，将自身化思想。

Generators, on the other hand, take mechanical energy – the rotation of a coil of wire – and use induction to convert it into electrical energy, in the form of a current running through a wire.

另一方面，发电机获取机械——线圈旋——并使用感应将其换电，以电流流过电线形式。

In general, metal foams are useful for high-tech shock and impact absorbers, the gas inside makes them extremely compressible, so they can absorb a lot of mechanical energy, while still retaining some of the strength and durability of a metal.

总之，金属泡沫对高科技震动和压力吸收帮助很大，内部气体让物质极度压缩，可吸收很多机械，而且依然保留金属强度和耐用性。
