Equidistance point and difference theory in theory of function approximation are studied. Meanwhile, the relation among difference, difference quotient and derivate is revealed. By drawing Lagrange's and Cauchy's theorem of mean on difference and Taylor's formula into difference function, four theorems, such as Lagrange's theorem of mean on difference, are concluded in simple way. On the basis of these conclusions, the asymptotic property of middle point is studied, a series of new conclusions are drawn and the discussions on the asymptotic property of middle point in differential mid-value are summarized.

对函数逼近论中等距节点和差分理论进行了研究，揭示了差分、差商与导数之间的联系；将Lagrange中值定理、Cauchy中值定理、Taylor公式引入到差分函数中，简明地推导出Lagrange差分中值定理等4个定理，并在此基础上对"中间点"的渐近性进行了研究，得出了一系列"中间点"的渐近性的结果，概括了有关文献对微分中值公式的"中间点"的渐近性的讨论；给出的引理改进了函数逼近论的证明方法，精简了函数逼近论中的一些内容。

To describe the asymptotic behavior of certain time series or random fields,many ways of modeling the weak dependence have already been work out.

为了描述某些时间序列和随机场的渐近行为，许多作者引入了随机变量的相依性概念，其中最流行的就是混合概念。

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。

Since the introduction, Ajax, a asynchronism pattern with the combination of the merits of both C/S and B/S, has taken the fancy of many developers and has become the hotspot in Web development.

中文摘要：自从Ajax这种结合C/S和B/S优点开发的异步模式被引入后，便受到很多开发者的青睐，成为了现今Web开发的热门。

Since the China telecom industry introduced competition mechanism, mobile service providers have developed themselves at a tremendous speed. Meanwhile, fixed-line telecom service providers, including China Telecom and China Netcom, are facing severe challenges. The network services and traditional telephone services provided by China Telecom can no longer fulfill the various requirements from customers. The ARPU value of the fixed-line telephone services keeps decreasing and the broadband network services becomes SP's information transmission channel due to lacking provision of contents.

自从中国电信市场引入竞争机制以来，移动运营商发展迅速，固网运营商（包括中国电信和中国网通）面临严峻挑战，中国电信所经营的网络业务和传统的电话业务已无法应对日益增长并趋于多样化的用户需求，固网话音业务ARPU值的持续下滑已成为不争的事实，宽带网络也由于没有自己的业务而成为SP的信息传输管道。

Based on the Miedema′s theory of electric charge shift,a modification of Mo-reen′s model of prediction of the lattice parameters in solid solution was approachedfrom the idea of the atomic size and separation in solid solution changing withsolute concentration.

根据Miedema电荷迁移理论，引入固溶体中原子尺寸和间距随溶质浓度改变的观念，修正了Moreen的固溶体品格常数预测模型。
