Meanwhile, it could be seen that there does not exist a confidence interval with width less than 0.5 because of the property of Poisson distribution. Based on these conditions, the author mainly carried out research into two aspects of this problem as follows. Firstly, by numerical and theoretical analysis, the author compares some existent confidence intervals, for example,"exact" confidence interval, Wald confidence interval and Bayesian confidence interval, and finds some deficiencies points of the confidence intervals, whose modification version has been proposed .Also, several better confidence intervals such asare also presented .Secondly, for given confidence coefficient and interval width, the author constructs a class of asymptotical two-stage interval estimate procedures. At the same time, under varies restriction of confidence coefflcientent interval width, the optional sample size of the first stage has been computed by numerical computation. The numerical computation shows that the method considered in this dissertation have good properties and applied value.

同时,由于Poisson分布的特性,我们知道不存在其参数区间长度小于0.5的置信区间,基于这些情况,我们主要展开了以下两个方面的研究:一是利用数值计算分析与理论分析的方法对现有的若干置信区间如"精确"置信区间,Wald置信区间,Bayes置信区间等进行分析比较,发现了一些缺陷,针对这些缺陷,我们进行适当的修正,并得到几种性质较好的置信区间如:修正大样本区间Jeffreys原则下置信区间二是针对已给定的置信系数与区间长度,我们提出了一种渐近的两阶段区间估计程序,并利用数值计算的方法,在各种置信系数与区间长度限定下,算出了最优的第一阶段观测次数,大量数据表明,本文考虑的方法性态良好,具有应用价值。

Reduced SQP based on orthonormal bases, orthogonal bases and coordinate bases are studied and compared. With the correction item introduced, the null-space move is adjusted and the reduced SQP based on coordinate bases decomposition is improved.●The key problem of steady-state data processing for RTOPT is studied. A new algorithm of simultaneous strategies for data reconciliation and gross error detection is proposed. Here the objective function that is constructed using maximum likelihood principle and joint distribution function is minimized. Efficient algorithm is developed which exploited the nonlinear lease-square structure of this objective function.

To now my look back on, what I get this brushstroke is as essential as what pay do not become direct ratio, after because of that the station finishs, I regret to close too less, that person says the interface is them place is done best with the industry, I just know later is he cheated me, because the interface before him is done very uglily, it is beautiful that when I help him do, he says with me 2500, actually he was spent 4000, I also did not say, the affirmation that loses what industry face anyway is this kind of person, too not responsible, because be ASP code and code is written so that do not have method to change at all, a few regulation are done not have, besides him himself, estimation knows without the person is how one kind writes a law, everybody should know the advantage of standardization now, the thing of standardization no matter who is taken go up in one's hand, same can operate, otherwise your thing became a rubbish to others hand, the likelihood is highest grade in your hand, but others is not used when going up, its what value also was done not have.

到现在我回过头来看,这一笔我得到的与付出的根本不成正比,因为那个站做完以后我就后悔收得太少了,界面那人说是他们当地同行业做得最好的,后来我才知道是他骗了我,因为他以前的界面做得很难看,我帮他做的时候他跟我说是花了2500,其实他花了4000,我也不说了,反正丢什么行业脸的肯定是这种人,太不负责,因为是ASP代码而且代码写得根本没办法改,一些规则都没有,除了他自己,估计没有人知道是怎么样一种写法,现在大家应该知道标准化的好处的,标准化的东西不管谁拿到手上,都一样的可以操作,否则你的东西一到别人手上就成了一件垃圾,可能在你手里是极品,但是别人用不上的时候,它什么价值也没了。

With constant on-the-job training and relentless television schedules that call for twelve-hour workdays, for every day of the week, these new graduates and others of the Japan cartoon market are finding themselves vastly outpaced by the demands of wealthy broadcast and satellite television stations (who in turn, contract studios for a fraction of the animated property's estimated worth).

由于持续的在职培训和要求每周七天每天24小时的无情的电视时间表,这些和其他在日本卡通市场中的刚毕业的学生发现他们已经远远跟不上富有的广播公司和卫星电视台(同工作室签合同分享动画财产估计价值的一部分)的需求了。
