YODA
尤达大师
Q. How much Force power can Yoda output?
Q．尤达大师的原力的输出功率有多大？
A. I 8217;M GOING TO-of course-ignore the prequels.
A．星战前传不在本文的讨论范围之内，你们懂的。
Yoda 8217;s greatest display of raw power in the original trilogy came when he lifted Luke 8217;s X-wing from the swamp. As far as physically moving objects around goes, this was easily the biggest expenditure of energy through the Force we saw from anyone in the trilogy.
在《星球大战》原三部曲中，最能够展现尤达大师原力风采的当数他把卢克的X翼战机从沼泽里提出来了。就物理移动物体这一点而言，尤达此举无疑是整个三部曲中消耗能量最多的一次。
The energy it takes to lift an object to a given height is equal to the object 8217;s mass times the force of gravity times the height it 8217;s lifted. The X-wing scene lets us use this to put a lower limit on Yoda 8217;s peak power output.
提升一个物体至一定高度所需的能量等于物体的质量乘以重力加速度乘以提升的高度。从尤达提起X翼战机一事中，我们可以猜出尤达最大输出能力的下限。
First we need to know how heavy the ship was. The X-wing 8217;s mass has never been canonically established, but its length has-12.5 meters. An F-22 is 19 meters long and weighs 19,700 kg, so scaling down from this gives an estimate for the X-wing of about 12,000 pounds (5 metric tons).
首先我们要知道一架战机有多重。X翼战机的重量从来没有官方的说法，但我们知道它的长度为12.5米。一架F-22战机长度为19米，质量19700千克，所以按比例算下来X翼战机的重量大约为5600千克。
Next, we need to know how fast it was rising. I went over footage of the scene and timed the X-wing 8217;s rate of ascent as it was emerging from the water.
接下来我们要知道提升的速度有多快。我又去看了一遍电影中这个场景，给X翼战机提出水面的场景记了个时。
The front landing strut rises out of the water in about three and a half seconds, and I estimated the strut to be 1.4 meters long (based on a scene in A New Hope where a crew member squeezes past it), which tells us the X-wing was rising at 0.39 m/s.
战机的前起落架用了约3.5秒才从水中出来，我估算了一下起落架的长度大约为1.4米（基于《星球大战4：新希望》中一名机组成员从起落架前挤过的场景计算），因而X翼战机的提升速度为每秒0.39米。
Lastly, we need to know the strength of gravity on Dagobah. Here, I figure I 8217;m stuck, because while sci-fi fans are obsessive, it 8217;s not like there 8217;s gonna be a catalog of minor geophysical characteristics for every planet visited in Star Wars. Right?
最后我们要知道达戈巴星球上的重力加速度。我目测自己要卡在这个问题上了，因为就算科幻迷们再狂热，也不太会有《星球大战》中去过的每颗星球的地质特性的目录表，对吧？
Nope. I 8217;ve underestimated the fandom. Wookieepeedia has just such a catalog, and informs us that the surface gravity on Dagobah is 0.9g. Combining this with the X-wing mass and lift rate gives us our peak power output:
不，我低估了影迷们的能力。乌奇百科上就有这么个目录表，从上面我们可以得知达戈巴的表面重力加速度为0.9倍地球重力加速度。算上之前得到的X翼战机的质量和提升的速度，我们可以计算出峰值输出：
