By calculating the LST and asymptotic series of the service-time distribution we analyze the steady-state waiting-time probabilities of M/G/1 queue system. We also extend the special caseγ=3/2 to the normal case. The results show that it will be helpful to analyze the heavy-tailed waiting-time distribution of self-similar traffic sources. This chapter also proposes a generalized packets loss method.

本章第一部分通过引入一类混合指数分布并证明此类分布服从Pareto重尾分布，得到相应的LST变换闭合形式及服务时间渐进级数，同时将形状参数γ=3/2时的服务时间及其LST变换推广到更一般的情形，较为有效地解决了重尾分布的信源排队等待时间分析问题。

So Beta distribution could be used as a unified distribution to denote practical optical measurement distribution. Solving the problem of calculating Beta distribution parameters and characteristic value.

在光学测量领域做了大量实验统计工作的基础上，用Beta分布表示实际测量工作中遇到的多种非正态分布，验证了Beta分布统示表示实际测量分布的方法可行。

The Gumbel-Hougaard Copula was employed to construct a bivariate joint probability distribution for describing flood peak and flood volume, whose marginal distributions are both the Pearson type Ⅲ.

利用Cumbel-Hougaard Copula构造边缘分布为PⅢ型分布的两变量联合分布，用以描述洪峰和洪量。

The distribution characteristics of primary neurons in skin referral area and gastric mucosa are that spinal ganglions present segmental distribution and superposing with each other,moreover,sympathetic ganglions present diffused distribution and have no segmental distribution,which may be the neural basis of treating visceral pain by intracutaneous- injection drug.

结论胃痛的皮肤牵涉区与胃黏膜初级神经元分布的特点是在脊神经节呈节段性分布且相互重叠，在交感神经节呈弥散性分布，无节段性分布，也相互重叠，这可能是皮内注药治疗内脏痛的神经基础。

Especially since Lindley and Smith (1972) addressed the thought of hierarchical prior distribution and Han (1997) provided the methods to construct hierarchical prior distribution, more achievements have been made on hierarchical Bayesian methods to be used for solving zero-failure data problem.

所谓λ的多层先验分布的构造方法——减函数法，主要是选取λ的减函数作为λ的第一层先验密度函数的核，第二层先验分布——第一层先验分布中超参数的先验分布取均匀分布。

This paper leads into the multinomial distribution concept and discusses the content in the following four aspects in details: First, defining the random vector is NA's, drawing out the nature of NA's for the multinomial distribution and proving the multinomial distribution is NA's; Then, introducing the way to own maximum values by three distributions, giving the method to gain the maximum value from general multinomial distribution, which is named the method of elimination.

本文引入了多项分布概念，同时详细讨论了以下四个方面的内容：1。定义了随机向量是NA的，并由此引出多项分布的NA性，并且证明了多项分布是NA的；2。介绍了三项分布最大值的求法，在此基础上给出了一般多项分布最大值的求法，即淘汰法。

The percent of Cosmopolitan genus increase along with the elevation, but the trend is contrary to that of the pteridophyte genus.

在垂直梯度上：种子植物属热带分布诸类的比例自海拔400至800米（～1100米）之间呈上升趋势，然后下降；温带分布的第8、9、10、11类随海拔而上升；地中海—中亚中心分布的第12、13类只见于比较干热的河谷地带；东亚分布和中国特有属在海拔900～1100m和1600～1800m段取得小的峰值；世界分布属的比例随海拔而上升，蕨类植物属则相反。

There are 11 population distribution cores obviously instead of a monocentric pattern.

结果是：沈阳城市内部人口分布具有较高的不均衡性和聚集性；城市人口密度分布不符合单核心圈层式范式，具有11个明显的人口分布核心；在城市中心区域，人口分布的区域化特征更为显著；人口分布主要受到相近的两个人口核心的影响。

To demodulate the OFDM signals accurately, channel estimation algorithms are adopted. This paper examines the slow-fading estimation algorithms based on block pilot arrangement: LS and LMMSE algorithms, as well as the fast-fading channel estimation algorithms based on comb-type pilot arrangement: linear and transform domain interpolation algorithms.

本文分析了导频分布的两种方案：1块状导频分布，对基于块状导频分布方案的慢衰落信道估计算法：最小平方和线性最小均方误差算法进行了计算机仿真，比较了二者的估计性能，以及各自的优缺点；2梳状导频分布，对基于这种分布方案的快衰落信道估计算法进行了研究，对两类经典算法：线性插值法和基于变换域的插值法分别进行了理论分析和计算机仿真。

But when a rectangular continuous data set appears to have a longer tailed than normal distribution or it contains some values that are influential on statistical inference with normal distribution, the multivariate t distribution becomes useful for multiple imputations as an alternative to the multivariate normal distribution.

在多重插补法的基础上，当一个矩形连续数据集看起来有一个比正态分布还长的尾巴，或者是它包含了一些对正态分布的统计推断有影响的数据，多元t分布作为多元正态分布的替代分布，对于多重插补来说变的很有用了。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
