By demonstration , the author studies the status of the equal opportunity of compulsory education in zhijiang , hubei province , describes the diversity which the infant and juvenile of the right age share the equal opportunity in educational resources , on the base of statistic about time and interspace distribution draws a conclusion that in zhijiang infant and juvenile of the right age share unequal opportunity of education in finance investment , teacher resource , learning content and school substance , at the same time , the author discloses the character of unequal opportunity in enrollment 本文从义务教育的性质和价值、国情、社会稳定和受教育者权利保护的角度分析了实现义务教育机会均等的必要性。用实证研究方法从时间分布特征与空间分布特征两个层面对湖北省枝江市适龄儿童、少年存在的享受教育资源方面机会均等的差异状况作统计描述，并得出如下结论：枝江市适龄儿童、少年在享受教育资源方面存在着机会不均等状况。
According to studying these influences , which are cauced by economic developing level , changes of life style and the regularities of distance deceding in tourist demand , distribution of time and psychology of choosing destination , this article analyses the fundamental conditions for developing lushan tourist and the temporary situation in tourist market , then discusses methods for further development 本文通过研究经济发展水平、生活方式变动等因素对旅游消费的影响，旅游需求的距离衰减规律、时间分布规律和目的地选择心理规律等的基础上，分析了庐山旅游开发的基础条件、旅游市场目前的状况，探讨庐山旅游市场进一步开发的途径。
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。
