We could just collect a bunch of data. For a material .What's the volume it occupies at some pressure and temperature?
对一种物质我们可以得到一系列测量数据,在给定的温度和气压下,它的体积是什么?
If we get the pressure in there just right, we will allow for gas electron collisions and then we get the glow that ultimately was sent through the slits.
如果我们把气压设置在一个适当程度,把气体电子碰撞也算在里面,我们得到的炽热,最终将通过裂缝传送。
That little zero, that little superscript means one bar always. OK.
这个小上标的意思,是处于1巴气压下。
It would be much better if you had a reference point that didn't care where the pressure was.
我们还需要精确地定义气压,你必须知道气压的大小,当然如果我们能找到一个。
As we increase the voltage, we get to a critical value at which it is possible to actually draw electrons across the gap.
当我们增加气压时,我们得到了一个临界值,在这个临界值上,将电子吸引过来是完全有可能的。
Now let's change the pressure and temperature and sweep through a whole range of pressures and temperatures and measure the volume in every one of them.
然后改变气压和温度,并且让气压和温度,取便所有可能的数值,测量相应的体积。
There's hardly any vapor pressure above your ice water glass.
冰水混合物上方,水蒸气的气压非常小。
It depends whether you're in Denver or you're in Boston.
00摄氏度,但沸点与气压有关。
