符号的

Methods in the second group use the cyclic prefix inserted into the OFDM symbol, they do not affect the data rate, but the performance is not agreeable, because the cyclic prefix is contaminated by inter-symbol interference in the multipath channel.

第二大类方法利用了OFDM符号中插入的循环前缀，不影响数据的传输效率，但由于循环前缀受到严重的符号间干扰的影响，这类方法性能不佳。

D Whyte is the first attempt to create a general symbol algebra mathematician, he created the algebraic symbols, by Descartes improved as a modern form.

韦达是第一个试图创立一般符号代数的的数学家，他开创的符号代数，经笛卡尔改进后成为现代的形式。

Because the weights are determined by the correlation of code sequence and estimation error of channels, which can be nearly determined by system load factor, we determine the sub-optimum weights by system load factor through simulations, and substitute the hard-decision symbol function by soft-decision hyperbolic tangent function to decrease the risk of error decision.

由于加权因子取决于前级符号估计的可靠性。也就是取决于扩频码互相关系数与信道估计精度，在随机扩频系统中，估计精度可近似由系统负荷决定，因此可根据系统负荷决定加权因子，以很小的性能降低代价换取计算量的极大降低。同时，为进一步降低误判风险，使用带有斜率控制因子的双曲正切函数代替常规的符号函数。

Then using the previous theoretical models, we improve the sign interactive model of fashion consuming in order to explain the function of sign identity of fashion consuming better and effectively.

随后在前人的理论上改良时尚消费的符号互动模型，以便更好的说明时尚消费的符号认同功能。

Ironically, despite the inappropriateness of his symbol in medicine, Hermes did play a small role in the origin of the true symbol of the physician.

讽刺的是，无论赫尔墨斯的符号在医学中出现是多么的不合适，他在医生真正的符号象征的诞生中确实扮演了一个小角色。

Because the advertisement designer is concerned with the audience, culture can influence advertisement. The more different in the culture, and the more different in the symbol. The incommutability of symbol in different society will be more clearly.

文化影响广告内容是因广告设计者在乎阅听人的反应，且三个社会的文化内涵差异越大，所表现出来的符号内容就越不同，符号本身的不可替代性就越高。

He introduced several notations used to this day, for instance the integral sign ∫ representing an elongated S, from the Latin word summa and the d used for differentials, from the Latin word differentia.

它引入了几个至今人在使用的符号，例如代表拉长S的积分符号∫，因为拉丁语summa的意思是"加和"，用d表示微分，因为拉丁语differentia的意思是"细分"。

The result tells that at the beginning of English learning, semantic competence plays a major part in causing pragmatic failure while in the senior stage; social cognitive competence is the major cause. The thesis based on the research result establishes a semiotic Competence Cultivating Teaching Model in which markedness theory ,theory of interlanguage and interculture and content teaching approach are used to improve semiotic competence and reduce pragmatic failure.

研究结果也对语言学习者和教授者提出了一个新的问题，即在语言教学过程中，如何适当考虑语义能力，解释能力和社会认知能力三者的关系，构建一个教学模型，可以把这三者整体纳入语用能力培养的方案之中，笔者尝试性的提出一个解决方案，借用当前的词义习得标记性理论，过渡语与过渡文化理论和内容教学法理论，构建了一个符号能力发展模型，认为该模型将有利于学习者提高符号能力，进而减少语用失误。

In a sense, what Cassirer did in"Philosophy of Symbol Pattern"was to explore and describe the logical process of symbol pattern from"myth"to"algnuage" to"science".

这一点，卡西尔在他的《符号形式的哲学》中为我们所做的就是去考察与描述从"神话"到"语言"再到"科学"符号形式的逻辑进程。

Her surviving scores reveal Caccini to have taken extraordinary care over the notation of her music, focusing special attention on the rhythmic placement of syllables and words, especially within ornaments, on phrasing as indicated by slurs, and on the precise notation of often very long, melodically fluid vocal melismas.

她幸存的分数显示卡奇尼已接管了她的音乐符号特殊照顾，重点是有节奏的音节词和安置特别注意，特别是在饰品上，措词如诬蔑指出，而在往往很长的精确符号，旋律流体声

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
