使用符号

A sound style rule bars the instructions of a program from using any numerical or textual constant directly; instead, they rely on symbolic names, and the actual values only appear in a constant definition (constant in Pascal or Ada, preprocessor macros in C, PARAMETER in Fortran 77, constant attributes in the notation of this book).

一条合理的规则禁止把任何数字或本文常数直接地使用在程序的指令中；而是依赖于符号名，并且真实的数值只在一个常数定义中出现Pascal或Ada的常数(constant，C的预处理程序宏， Fortran 77的叁数，在本书符号中的常数属性。

Using many symbols makes it possible to put a large amount of inFORMation ona single map.

使用多种多样的符号可以在一张地图里放进大量的信息。

Scanning each character in the expression to separate and record operators, operational symbols and data types of operators, when expression being correct in syntax, recording interpreter executive order based on precedence of operator, a general expression interpreter is designed. The interpreter not only is used for numerical value and string computation, but also is easy to extend its functions, and when batch converting data, it could catch run error and continue to successive data.

2通过对公式的一次扫描，记录操作数、操作符号和操作数的赋值特性，并在语法正确的情况下，记录公式基于算符优先级的解释执行顺序，设计了通用公式解释器，它不仅可以进行数值运算、字符运算，而且可以对使用的函数库方便地进行扩充，在批量进行数据转换时，可以记录运行时错误，而不影响后续数据的执行。

Otherwise, you can use the empty space opposite to the CAMERA FRONT sign for line connection.

另外，还可使用与CAMERA FRONT 符号相对的空闲的空间，进行线路的连接。

An ordered set of symbols used in a language, e.

某种语言所使用的符号的有序集合。

In this paper, anovel mechanism based on orthogonal decomposition is proposed for joint timing recovering and multi-path components detection.

该文给出了采用基于正交分解进行脉冲同步的方法，相对于传统的使用匹配滤波器进行的定时估计和接收，具有结构简单，实现方便，在室内密集多径信道下和极大的符号间干扰下均能稳定工作的特点。

Finally, by introducing the differential relations into a kind of orthogonal PN sequence, a joint algorithm using the PN sequence as the training symbol can be got, and it can find the timing position accurately.

最后对一组正交PN序列引入差分关系，提出了一种在AWGN信道下只使用该序列作为训练符号即可完成联合同步的算法，该算法能获得准确的定时同步位置。

The method of multilevel parallel phase modulation was proposed, which means two parallel multilevel phase shift keying signals were transmitted with one frequency at the same symbol period.

提出了高阶并行相位调制的方法，即在同一调制符号周期，使用同一频率、并行发送2路携带不同信息的高阶相位调制信号。

It is handy to use the parentheses and the pipe symbol together.

这是方便使用圆括号和管道符号在一起。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
