尺度

Through simple Gaussian line fits, we found not only obvious Fe K line variability with no significant difference in the X-ray continuum flux between two ASCA observations which were separated by～440 days, but also rapid variabilities of Fe K line on time scales～10〓s within the second observation.

使用简单的高斯线拟合我们发现，在间隔440天左右的两次ASCA观测之间，NGC 4051的铁Kα荧光线轮廓和强度有着明显变化，而与此同时X射线连续谱流量保持不变；不仅如此，我们发现在第二次ASCA的观测过程中，NGC 4051的铁Kα荧光线有着10〓s尺度上的快速变化。

Have been developed. However, these approaches are all complicated in the description of physical mechanism and expensive in the consumption of computational resource, even encounter the convergence problem of the computer algorithm when the size parameter, the asphericity, or the refractive index of the scattering particle becoming too extreme.

然而，这些方法在物理机制的描述上过于复杂，并且要求占用极大的计算资源，甚至会出现难以克服的收敛性问题（当一些关键参量如粒子的尺度，非球性，折射率变得极端时）。

X-Digital system company-- the Blackfin processor that ADI firm used in the compositive satellite receiver that a broadcast transmits systematic manufacturer to contain FM modulator in its. X-Digital system company uses Blackfin processor, offerred a kind of such products, promise satellitic operation business to convey digital frequency to still do not have the market that open far-- much resident is unit , for example hotel and apartment building. The satellitic receiver of X-Digital company changes digital satellite signal into the FM imitate signal that can be identified by receiver of consumptive assonance frequency.

X-Digital 系统公司--一家广播传输系统制造商在其带有FM调制器的集成卫星领受器中采用了ADI公司的Blackfin措置器。X-Digital系统公司采用Blackfin措置器，供给了如许一种产物，答应卫星运营商将数字音频传送到远远还没有翻开的市场--多住户单元，例如酒店和公寓大楼。X-Digital公司的卫星领受器将数字卫星信号转换成可被尺度的生产类音频领受器识此外FM模拟信号。

Especially, we study the multi-scale asymptotic expansion and high accuracy algorithm for perforated composite materials in details.

第一章介绍了本文的目的与意义以及复合材料和多尺度有限元方法的重要性，给出了本文的一个概要。

Approximate methods have been developed, including the method of averaging, boundary layer method, methods of matched asymptotic expansion and multiple scales and so on.

近似求解方法已被发展，包括平均法，边界层法，匹配渐近展开和多尺度法等等。

In this paper the defect of the traditionary boundary layer methods (including the method of matched asymptotic expansions and the method of Visik-Lyusternik) is noted, from those methods we cannot construct the asymptotic expansion of boundary layer term really.

本文指出传统的边界层方法包括匹配法和Vi(？ik—Lyusternik方法的不足：不能作出边界层项的渐近展开式。提出多重尺度构造边界层项的方法，得到符合实情的结果。

The homogenization method uses the asymptotic expansion of small parameters, and the effective properties of composite materials are extremum, which are different from the real properties of composite materials.

事实上，多孔材料物性参数测试结果与均匀化计算结果均存在一定差异，这种差异就是材料的尺度效应。

By sampling from the traffic flow and averaging non-overlapping blocks of size m from the original series, the variance asymptotic characteristic of the averaged series is obtained, from which this method shows that the splitting, assembling and merging process of the convergence mechanism will not change the Hurst parmeter of the traffic if the queue length of assemble buffer has a finite second-order moment.

在分析光突发交换边缘结点汇聚机制的基础上，提出了一种基于方差时间图的分析方法，利用"时间离散"和"尺度聚集"的思想，通过构造不同聚集级别m的聚集序列，分析得出业务流时间聚集序列的方差渐近性，从理论上证明了在组装器队长具有有限二阶矩的条件下，汇聚机制的分解、组装和合并过程不会改变业务流的Hurst参数。

Kulldorf'book(1961)sysmatically studied the MLE of the location and scale pa-rameters belonging to the exponential family,Kulldorf proved that the MLE wasconsistent and has asymptotically normal distribution.

Kull-dorf（1961）在所著的书里系统地研究了如何利用分组数据求指数分布族的位置参数与尺度参数的最大似然估计，并且证明了MLE的相合性与渐近正态性。

As a new technology,nanotechnology studies the run rules and characteristics of the electron,atomy,and molecule in the scale of 0.1 nm~100 nm.

0引言纳米技术是指在0.1 nm~100 nm的尺度空间内研究电子、原子、分子的内在运行规律和特性的崭新技术[1]。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
