"Now if you look at that bottom picture on your pages, you'll see that you can measure the length and the width of that spatter droplet,right?
VOA: special.2010.05.05
Now you have this situation where you have a droplet that is net negative or perhaps net positive.
现在的情况是那些液滴,可能是净负电,也可能是净正电。
Let's plot droplet velocity as a function of looking at the number that have this velocity 0 with the zero being in the center here.
我们将液滴的速度设定为,观察那些数字作用,在中心的地方,速度为。
If I get you down to a cluster of about 30 water molecules, the boiling point is a function of the size of the water droplet.
如果对于一个由30个水分子,组成的簇,沸点是,水珠尺寸的函数。
When the charge is applied, if the upper plate is negative, we would expect that the negative droplet would be repelled at a rate exceeding the gravitational fall.
当电荷起作用时,如果上边的板子是负电的,我们可以期待负电的液滴会,超过重力下降速度的速度被排斥。
He reasoned then that the charge, since he could vary voltage continuously but got a discontinuous variation in velocity, his conclusion was that the charge must be discontinuously attached to the droplet.
他推断出电荷,因为他可以不断地改变电压,但是得出了速度是在不连续变化着,他的结论是电荷,是间断地依附于液滴上的。
