积项 meaning in Chinese

product term

In queueing theory , the research on gi / g / l queue have been continued for decades of years . by the end of last century , the integral representation of its transient distribution of the queue length has been obtained . in this integral representation , the integrated term can be determined recursively by a system of kolmogorov differential equation
在排队理论中，关于gi / g / 1排队系统的研究，延续了几十年，直至上个世纪末，方得到了它的瞬时队长分布的积分表示，在这个积分表示中，其被积项可以由一组柯尔莫洛夫偏微分方程递归地确定。
3 , 4 , 5 and ? 6 of this chapter deal respectively with the transient distribution of the queue length of these four queueing systems . such results are obtained as follows : under the condition of the interarrival times distributions and service times distributions of these queueing models which have density function , their transient distribution of the queue length can be represented as an integral , and the integrated term of this integral can be recursively obtained
在这一章的夸3 、芬4 、县5和号6中，分别针对这四个排队模型，讨论了瞬时队长的分布，最终得到了以下的结果:在这几个模型的到达间隔分布和服务时间分布均具有密度函数的条件下，它们的瞬时队长分布可以表示为一个积分，该积分的被积项可以递归地求取。
