符号

Notational systems varied widely from person to person, school to school, and region to region, and Chiang K'uei was in any event probably exceptional among literati in entering—by employing a written system at all—what was more comfortably the province of trained musicians.

符号系统不仅人人有异，而且流派于流派、地区于地区之间也是各自相异，姜夔出人意外地是使用书面符号系统——其对于训练有素的乐师而言不是难事。

You shouldn't have to read every word of every paragraph to find the tips you want — they should be listed in bullet points or a numbered list, or highlighted in bold or somehow brought to the attention to the reader.

你不用阅读段落里的每个字去找你想要的贴士——它们应该要用标志性符号或者是数字清单，或者是用黑体或者是其他能够引起注意的符号来标示。

No additional data for frequency tracking are need, but higher estimation accuracy and low computational complexity can be obtained. Finally, a kind of optimizing joint algorithm for symbol timing, frequency synchronization and channel estimation is proposed. The false alarm probability and miss detect probability of the symbol timing are derived. We proved that the time－frequency offset domain random sequence sliding in the frequency offset direction is orthogonal with the original random sequence, and proposed a new integer frequency offset estimation algorithm. The coarse estimation methods for fractional frequency offset both in AWGN and multipath channels are proposed too.

最后，提出了一种优化的符号同步、频偏估计和信道估计的联合算法，推导了符号同步方法的虚警概率和漏检概率，给出了随机序列在时间－频率偏移域沿频率偏移方向滑动后与原序列近似正交的证明，提出了一种新的在时间－频率偏移域沿频率偏移方向进行滑动相关估计整数频偏的方法，提出了在AWGN信道和多径信道下进行小数频偏粗估计的方法，给出了小数频偏细估计的ML估计结果和利用频域PN序列取值特性的简洁的信道估计结果。

A pair of sign pattern row vectors allows orthogonality if the two vectors are the sign patterns of two real orthogonal row vectors.

一对符号模式行向量是蕴含正交的，若存在一对与它们有相同符号模式的正交实行向量。

A square sign pattern matrix that does not have a zero row or zero column is sign potentially orthogonal if every pair of rows and every pair of columns allow orthogonality.

一个没有零行或零列的 n 阶符号模式矩阵是符号蕴含正交的，若每一对行和列向量都是蕴含正交的。

By analyzing inverted color perceptions and ostensive definition, this paper proves that our sensations are also symbols and a symbol is totally different from the material property reflected.

本文通过颠倒色觉和实指定义分析，证明我们的感觉也是符号，一种符号和它反映的物性完全不像似。

Why is it important to know the relations a sign has with others, such as syntagmetic and paradigmatic relations?

了解符号和符号之间的关系，如组合关系和聚合关系，为什么是重要的？

Give a projecting plane,sign volume of pentahedron for each triangle in mesh,which is constructed by the triangle and it projection in projecting plane,is computed.Volume of the mesh is algebraic sum of all pentahedrons' signed volume.Triangles will be partition into several smaller triangles when necessary.

该方法通过指定投影平面，计算每个三角面片及其在投影平面上的投影所围成的凸五面体的带符号体积（必要时对三角面片进行细分），整个模型的体积为所有凸五面体带符号体积的代数和。

This symbol appeared on the Peso , and looked much like the modern$ sign.

这一符号出现在比索上，很像今天$一符号。

This symbol appeared on the Peso, and looked much like the modern $ sign.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
