符号的

Firstly, we get the necessary and sufficient conditions for Toeplitz operators that commutes with another such operator whose symbol is a monomial, meanwhile, we completely characterize when the mellin transform of the bounded function on the interval 0,1 is a rational function.

首先得到了以有界函数为符号的Toeplitz算子和以单项式函数为符号的Toeplitz算子可交换的充要条件，同时给出了0，1区间上的有界函数的Mellin变换为有理函数的充要条件。

For each layer-divide symbol appeares regularly in weave diagram, the layer-divide symbol is affirmed first,then the attribute of each yarn and weft is fixed,the weave of each layer is analyzed at last. As to leno fabric, the reverse side of the fabric should be analyzed, tell the crossing warp from normal warp before drafting the looming draft.This paper introduces the method to analyze this kind of complex fabric through above two examples.

对四层织物分析时，找出组织图上有代表性的组织点的属性，因分层符号在组织图上出现时很有规律，可以先确定各层分层符号的位置，进而确定各根经纬纱的属性，分出各层织物，最后分析各层的组织；纱罗织物分析时，应分析织物的反面，先要区分出绞经和地经，然后才能绘出组织图。

But symbols like "five-pointed star,""portrait of leader," and etc. are not standard format of "Cultural Pop," and Huang Gang excluded the most common elements in Chinese Contemporary Art:"persiflage,""mocking,""sarcasm"– these has been seen as flightiness and kitsch in current art world. In contrast, his usage for these symbols as almost "abstract," and with a bare outline and a section of changed and coordinated color could create settled and dignified visual effect.

但"五星"、"领袖像"等符号并非标准的"政治波普"形式，黄钢采取了一种意象化的方式来呈现它们，剔出了1990年代以来中国当代艺术中常见的"戏谑"、"调侃"和"讽刺"——这些方式，在眼下的艺术世界中，已然变得轻浮和媚俗；相反，他对这些符号的表现几乎是"抽象"的，仅仅一个轮廓，一片变化而协调的颜色便能做到，在视觉效果上显得沉稳而凝重。

In the third chapter "Utterly exhausted", analysed expressly those long-lens and jump-cut; In the fourthly chapter "alpha city",analysed expressly the aesthetic purpose of black and white and simulacrum; In the fifthly chapter "Chinese girl",put emphases on the color and component line;In the sixth chapter "madman Pierrot",analysed expressly color and dissymmetry composition of a picture through psychology; In the seventh chapter "carbinier",analysed lens language from film semeiology; it researched Chinese film in eighth chapter,explained detailedly a successful Chinese films;"Yellow land",analysed presentation format of The sign "China".point out our Chinese film various problems in inditing concept as well as film system.

第八章是对中国电影的研究，提出戈达尔对我们中国电影一些有益的启示，分析了一部成功的中国影片《黄土地》，从电影符号学的角度去分析"中国"这个符号的呈现方式。还指出了中国电影目前存在的一些问题，有电影创作观念上以及中国电影体制等方面的原因。

Differential modulation is also a widely used method to the case of no knowledge of the channels in the receiver. Here we propose noncoherent sequence detection for differential space-frequency modulation, which can be used to alleviate the error floor that occurs in a multipath channel with long time delay expansion.

在接收端不知道信道状态信息的情况下，差分调制也是一种被广泛采用的技术，论文提出了应用于差分空频调制的非相干序列检测方法，该方法通过积累多个符号上的信道信息来完成发送符号的检测，可以消除由于长的信道延迟扩展带来的误码平层。

Because the creation was spontaneous,the symbols were various,ununited and therefore could't be used commonly.

由于创造符号的行为是自发的、各行其是的，因而创造出来的符号是各种各样的、极不统一的、无法共同使用的。

From the connotation of Derrida's différance and the language point of deconstructionism, a phenomenon can be found that the component sign of any language is not self-sufficient, but has a complex relationship with other elements involved, not only possesess the trace of other signs, also has their unique differences, which outstands their own value when forming the differences.

从&异延&的内涵和解构主义的语言观可以看出：任何语言符号的组成要素都不是自足的，而是与周围其他成分有着漫无头绪的复杂关系，既带有其他符号的印迹，但又彼此有别，并在形成差异时突显自身的价值。

"Formalists believed mathematics to be the manipulation of configurations of symbols according to prescribe d rules, a "game" independent of any physical interpretation of the symbols."

形式主义相信数学是按照预先规定好的规则来操纵一些符号的配置，是与这些符号的任何物理解释无关的一种「游戏

But just as a computing machine cares nothing for the significance of symbols it processes, so minds – or their physical 'realizers', brains – care nothing for the meanings of symbols in the language of thought: mental processes are purely 'syntactic'.

正如一个计算机器关心的仅仅是运行符号的含义，所以心灵（或它们的物理实现者，大脑）关心的也无非是在思想语言中的符号的含义：精神过程，仅仅是&句法的&。

In chapter 3,a based on pilot symbols channel estimation method and its simplifiede method are discussed in detailed. In this chapter we bring forth a method that is fit to the extremely fading channels.

第三章介绍了一种基于导引符号的MIMO-OFDM系统的信道估计方法及其改进型方法，同时提出了一种适合于极端衰落信道条件下的基于导引符号的信道估计方法。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
