now I'm really fantastic at drawing this mechanical device, but you can imagine that dropping a weight can cause a paddle wheel to turn.

机械装置的时候,我真的很着迷，你可以想象,当重物掉落的时候会带动桨轮旋转。

And so this is really a mechanical term, if you like, and this is electrostatic or coulombic.

所以说这真算是一个力学问题，你愿意的话，也可以说它是,静电学或库仑定律方面的问题。

This is a story about mechanical objects, -- some of which move-- -- remember those smiling houses in the background-- and some of which are stationary, but they're all mechanical objects.

这是一个关于会活动的，机械的故事-,还记得那些作为背景微笑的房子吗？,它们不会动但也都是机械的东西。

This is visualizing the process of the conversion of mechanical energy into chemical and electrical energy very nicely.

这一模拟恰到好处地演示了,机械能到化学能和电能的转换过程。

In some sense, that's one reason to associate this as a kind of energy, H just like mechanical energy u or enthalpy H, it's the minimum free energy state that is the equilibrium state under the relevant conditions.

在某种意义下，这是我们把这些物理量称为能量的原因，就像机械能U和自由焓，具有最小自由能的状态在特定的条件下,就是平衡态。

So the two points of interest of research are how does it work this conversion of mechanical energy into electrical energy how are we able to bring back lost hair cells to cure deafness.

因此这项研究的两个关键点,一是机械能,是如何转化成电能的,我们能不能通过修复受损的毛细胞,来治疗耳聋。

This conversion from a mechanical energy into a chemical energy can be nicely visualized when one fills a hair cell with a sensitive die that responds to the calcium ions that influx into the cell.

如果在毛细胞中注入,对钙离子敏感的物质,可以精确地模拟,这一机械能到化学能的转化过程。
