符号的

One of the most important issues of pulse position modulation for optical wireless communications is the receiver symbol synchronization subsystem, in this paper, the basic principle of symbol synchronization for PPM sequence is discussed, and the upper limit of exact synchronization probability for random PPM sequence is analyzed.

讨论了PPM序列的符号同步原理；在分析随机PPM序列的精确符号同步概率上限的基础上，给出了一种在PPM序列中插入同步信号来实现PPM精确符号同步的方案及其数字逻辑电路实现。

The newspaper, a kind of plane carrier, whose external images are constructed by visual symbols. Visual and non-linguistic symbols have more effect than written language on readers' vision so that readers can get deeper understanding and impression of the newspaper.

报纸作为一种平面载体，它的外在形象是由视觉性符号构造出来的，而且视觉性非语言符号要比文字语言符号在视觉上给读者的视觉冲击更大，也更能加深读者对报纸的认识和记忆。

The method of constructing the sign patterns that allow orthogonal matrix is given.

给出蕴含正交矩阵的符号模式的一种构造方法，并证明了一类给定符号模式蕴含正交矩阵，最后对蕴含正交矩阵的符号模式中零元的个数进行了研究

Yang Xiong, the Han era philologist, once said"Speaking is the sound to express inner heart, while writing is the drawing to describe inner world," which means language is a vocal symbol and character is a drawing symbol.

意思是，语言是表达内心思想的声音符号，文字是表达内心思想的图画符号，也就是说，文字不是通过记录语言而表意的，文字本来就不是记录语言的符号，而是直接表意。

Then I need to make sure I've got the symlink set up correctly in each runlevel where I want it to run, and if I happen to need it to execute between two scripts that are consecutively numbered, I need to do some symlink renumbering (e.g., if S10xxx and S11yyy exist, and I want zzzz to run between, I need to resymlink one of those files to squeeze zzzz between them).

然后，我必须确保在每个要运行这个服务的runlevel中正确地设置好符号链接。假如恰好这个服务需要在已经连续编号的两个脚本之间运行，我就需要做一些对符号链接重新编号的工作(例如，S10xxx和S11yyy已经存在，而我想让zzzz在它们之间运行，我就需要对前两者之一重新建立符号链接来把zzzz挤进去)。

So, for the study of Semeiology, dig more symbolic characteristics, use more exact semeiology principle to do the visual communication design is a thing which have a special significance.

因此，对于符号学的研究，发掘更多的符号特性，更准确的运用符号学原理来进行视觉传达设计是极具意义的。

His Semiotics Theory is focused on the sign itself and the relationship between signs.

他的符号学理论主要关注的是符号自身和各个符号之间的关系。

Sociosemiotics is a theory that stems from semiotics, the science of the life of signs in society.

社会符号学是在符号学（一门研究社会生活中符号生命的科学）的基础上发展起来的一种理论。

Meteorological and oceanographic symbology is the only set not under the standard's control: rather, they are imported from the symbology established by the World Meteorological Organization .

气象和海洋象征符号不仅仅是一套标准控制的符号，更合适的说，它们是来自于世界气象组织的象征符号。

Finally this paper consideres an applicable case-the symbolic transition graph,then the generalized symbolic observation graph SOG and symbolic congruence graph SCG can be finite,so authors' algorithm is feasible for weak bisimulation and observation congruence.

此时由符号双迁移关系生成的符号观察图和迟符号同余图必为有穷图，因而我们的弱互模拟等价算法是可行的。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
