probability density function

基本解釋

This cartoon shows the probability density function of 1s.
下麪這個(gè)動(dòng)畫(huà)表示了,數(shù)1s軌道的概率密度函數(shù)。
Well, it depends on what you know about the measurements' probability density function (PDF).
它依賴於您對(duì)度量值的概率密度函數(shù)（probability density function，PDF）的認(rèn)識(shí)。
Figure 1 shows a typical normal probability density function, so called because most observations fall into this sort of distribution.
圖1顯示了一個(gè)典型的正態(tài)概率分佈函數(shù)，這樣命名是因爲(wèi)絕大多數(shù)值都屬於這個(gè)分佈範(fàn)圍內(nèi)。

We can graph out what this is where we're graphing the radial probability density as a function of the radius.
我們可以，畫(huà)出它來(lái),這是逕曏概率密度,作爲(wèi)半逕的一個(gè)函數(shù)圖。

We can talk about the wave function squared, the probability density, or we can talk about the radial probability distribution.
我們可以討論它,波函數(shù)的平方，概率密度，或者可以考慮它的逕曏概率分佈。

a function representing the relative distribution of frequency of a continuous random variable from which parameters such as its mean and variance can be derived and having the property that its integral from a to b is the probability that the variable lies in this interval. Its graph is the limiting case of a histogram as the amount of data increases and the class intervals decrease in size (Also called density function) &rarrcompare cumulative distribution function ,frequency distribution
