程序指令

Programming with customer macroinstruction is a kind of the advanced programming method,which is offered by FANUC CNC system,The function code or address can be replaced by variable during the programming.

用户宏指令编程是FANUC系统所提供的一种先进的编程方法[1]，使用变量代替程序中的功能代码或地址值进行编程，使数控程序具有通用性和灵活性，且简化数控编程，是数控技术的重要组成部分。

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。

All that we have been giving programmers is an optimizing compiler, which mysteriously does something to the programs it translates but which never explains what it does.

我们所给予程序员的只有优化过的编译器，它只会神秘地将程序翻译成机器指令，却从来不解释为什么。

This allows you to see each instruction in your program as it executes, and to examine your variables as they change during the life of your program.

这就允许你看到程序执行时的每一条指令，查看在程序运行期间变量的变化。

A program that translates an instruction into a machine language and executes it before proceeding to the next instruction.

数字计算机借此把高级语言编写的程序中的指令翻译成与其等价的机器语言程序的处理过程。

Also study the method of building machining control parameter and NC program contraposing command format of the NC system.

根据鞋楦数控系统的指令格式，研究了数控加工程序中控制参数的确定以及数控加工程序的生成方法。

By the research to computer virus characteristics,such as ruinousness, infectivity and uncertainty,according to the different classification of virus this paper analyzes the operating principle of computer virus respectively,and discusses some methods to clearing the computer virus.

因此，计算机病毒的防治对于维护系统的正常运行非常重要。1计算机病毒的特征计算机病毒是指编制或者在计算机程序中插入的破坏计算机功能或者毁坏数据，影响计算机使用，并能自我复制的一组计算机指令或者程序代码[1][2]。

When you "trace" a program, the program stops after executing each instruction, giving you the chance to examine the values of registers/memory.

当你跟踪一个程序时，在执行了每一条指令后程序都会停止运行，以便给你一个机会，让你能分析寄存器和内存。

Within RISC,teams of hardware engineers and complier architects work together to forge a unified design ne that will minimize the hardware complexity by integrating in hardware only such instructions that are justified by their occurrence in program trace analysis.

在RISC中，硬件工程师的编译设计师合作制定出一个统一的设计思想：即通过仅将那些由其在程序跟踪分析中的出现而正式的指令集成于硬件，从而将硬件的复杂程序降为最低。

Computer science a program that decodes instructions written in a higher order language and produces a machine language program.

用更高命令语言所写的解码指令程序来产出机器语言程序。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
