概率密度函数 [数] probability density function
- 下面这个动画表示了,数1s轨道的概率密度函数。
This cartoon shows the probability density function of 1s. - 在信号处理的应用中,经常需要计算双变量高斯概率密度函数在四个象限上的积分值。
In signal processing applications, it is often required to compute the integral of the bivariate Gaussian probability density function (pdf) over the four quadrants. - 根据信号、本底的时间分布以及时间、时间误差、质量、质量差等变量之间的关系,构建概率密度函数。
The probability density function (PDF) is constructed from the time distributions of signal and backgrounds and the relations among time, time uncertainty, mass, and mass difference variables.
