arithmetic expressions造句
例句与造句
- note that our discussion of this classic approach will be somewhat simplified : arithmetic expressions will contain only operands, binary operators, and one kind of parentheses
注意到我们谈到的这个经典算法有些简化：算术表达式只包含操作数、二元操作符和一种括号。 - as an example we will write a small program to read and evaluate arithmetic expressions consisting of floating point numbers, parentheses and the usual operators for addition, subtraction, and so on
例如我们要写一个计算由浮点数、圆括号及一些常用的加、减等算术符号组成的算术表达式的程序。 - my master dissertation was supported by the natural science foundation of china . i researched how to measure the characteristic parameter of filed emitters array ( fea ) and acquired the characteristic arithmetic expression
根据场发射的特性，研究其特性参数的测量，以及根据测量结果计算出各参数间的关系式。 - the dissertation mainly deals with the data acquisition circuit, the communication between measuring instrument and computer and how to process the measured data and acquire the characteristic arithmetic expression
测量仪采用89c51单片机作为其控制核心，其数据采集分辨率为12位。本文重点讨论了数据采集电路的实现、仪器与计算机的通信以及对测量数据的处理。 - a column name is required only when a column is derived from an arithmetic expression, a function, or a constant; when two or more columns may otherwise have the same name, typically because of a join; or when a column in a view is specified a name different from that of the column from which it is derived
仅在下列情况下需要列名：列是从算术表达式、函数或常量派生的；两个或更多的列可能会具有相同的名称（通常是由于联接的原因）；视图中的某个列的指定名称不同于其派生来源列的名称。 - It's difficult to find arithmetic expressions in a sentence. 用arithmetic expressions造句挺难的
- working at automatic mode the system can transmit the data to computer through the parallel port which work at epp ( enhanced parallel port ) mode . then the computer shows the characteristic relation curves and acquires the characteristic arithmetic expression . the sampling frequency reach to 4khz, the core of control system is microcontroller uint ( mcu ) 89c51 ， the data acquisition is 12 bite
也可以工作在自动方式下通过并行接口（工作于epp模式），把测量到的数据输入计算机，在计算机上显示特性参数间的关系曲线，以及求出参数间的数学关系式，其采样频率可达4khz。
