1·Its two sides install the paddle wheel which can rotate.

它的两舷装着会转动的桨轮。

2·Work was done in turning the paddle wheel against the resistance of the water.

转动搅拌轮，克服水的阻力做功。

3·Mann found that by rotating his bottles in the water with a device similar to a paddle wheel.

曼用一种与浆轮相似的装置在水内旋转水瓶，发现了这一点。

4·The most obvious production of thrust comes from pushing back on the water like a paddle wheel.

最明显的推力来自于手臂的向后推水，就像圆盘明轮那样。

5·The straight arm is brought around in a full circle, with the hand flat (see paddle wheel figure).

直臂划手是把手臂绕一个整圈，手平放(就像明轮的图)。

6·Interestingly, the paddle wheel or propeller style movement creates lift and thrust. In this case lift adds to thrust.

这个很有意思，明轮推水或者桨叶方式的推水产生了上举力和向前的推力，在这种情况下上升力和推力会叠加在一起。

7·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。

8·So, it's a trivial matter, by looking at what is the weight and how far does it drop, to say OK, how much work is done by the paddle wheel.

好，让我们看看重物的质量,以及它下落的距离，就知道桨轮做了多少功。

9·Oar oar oar ships to change paddle wheel forward, the oar oar paddle wheel instead of the intermittent advance of the roundabout forward (continuous operation).

桨轮船把桨楫改为桨轮推进，把桨楫的间歇推进改为桨轮的回旋推进(连续运转)。

10·Now you could do a similar sort of thing, but instead of having a candle, you have a paddle wheel, and the paddle wheel is spun by a weight that's dropping from here to here.

那接下来可以做一件类似的事，但不再是蜡烛，我们将它换成一个桨轮，桨轮末端拴一个重物，它可以从这掉落到这。
