汉英语境1
英译术语:
Coxian-2 distribution
汉语语境:
该Coxian-2的分布是排队列和可靠性分析一个非常有用的分布。重要的是要知道当一个一般的概率分布可以通过一个Coxian-2-分布来近似拟合前三分之一时刻。对于变化大于1的平方系数是一个正随机变量，其已知的下界的第三个时刻是存在的三个时刻的配合。为了完成该图，在本说明不足和第三时刻上界衍生时变化的平方系数是0.5和1之间的情况下。另外，我们表示出C 2分布对应的这些范围。
英语语境:
The Coxian-2 distribution is a very useful distribution for queuing and reliability analysis. It is important to know when a general probability distribution can be approximated by a Coxian-2 distribution by fitting the first three moments. For a positive random variable with a squared coefficient of variation larger than 1, a lower bound on its third moment is known for which a three-moment fit exists. To complete the figure, in this note lower and upper bounds on the third moment are derived when the squared coefficient of variation is between 0.5 and 1. Also, we characterize the C2-distributions that correspond to these bounds.
