That's different when you have continuous values-- you don't have P because it's always zero.
和离散型随机变量的分布不同的是,连续型随机变量的分布中,某一点的概率值始终是零
We will always have r equals zero in these radial probability distribution graphs, and we can think about why that is.
在这些径向概率分布图里,总有r等于0处,我们可以考虑为什么会这样。
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。
So my answer is always going to be zero and therefore almost always going to be wrong. Yeah?
所以我的答案总会是,因此,几乎这总是错误的,对不?
It is always a number that lies between zero and one, or between 0% and 100%.
概率一定是一个在0和1之间的数字,或者说0%和100%之间
In other words, T surrounding dS has to be greater than zero, and of course temperature is always positive.
换句话说这就意味着,环境温度T乘以dS必须大于零,当然环境温度T是正的。
Thus far, we always put what after the zero?
至此,我们总在在0后面放置什么?
So I said before when we were talking about single atoms, we always define the zero energy as when an electron was actually ejected, but now, when we talk about chemical reactions taking place, it's very, very rare that we're actually going to be talking about anything that gets to this point here.
我之前说过,当我们讨论单个原子的时候,我们总是把零点能,定在电子被发射出去以后,但是现在,当我们讨论化学反应发生的时候,非常非常罕见出现,确实达到,这种程度的情况。
In other words, we choose a convention for the zero of entropy, so that then we can write entropies of products and reactants always referring to the same standard state.
换句话说,我们选择了一个,焓零点的约定,这样我们,就可以总是相对于同样的标准,状态写出生成物和反应物的焓。
The answer is always going to be zero.
那个答案总归是。
isothermal always means delta u equals zero.
理想气体。
What they did was they got subjects to participate in a psychological experiment and the experiment consisted of asking the subjects questions that had quantitative answers, which were always numbers from zero to one hundred.
他们找了很多人作为实验对象,参加这个心理实验,在实验中会问这些人,需要量化回答的问题,答案范围是从0到100
