The net - culture entwined with digital computer communication is a kind of " individual culture " that cherishes individual value and a kind of power - distributed culture as well 由数字计算机交往编织起来的网络文化是一种注重个性价值的“个性文化” ；是一种权力分散的文化。
To enable a digital computer to work with analogue , an analogue - to - digital ( a / d ) converter is needed to transfer analogue into digital data then stored in the random asses memory ( ram ) installed in the computer 为了使数字计算机能够工作，必须要有一个模数转换器将模拟信号转换为数字信号并存在计算机ram中。
Modern control theory has arisen with the advent of high - speed digital computers and characterized by the state variable concept with emphasis on matrix algebra and with analysis and design principally in the time domain 现代控制理论是随着高速数字计算机的出现而产生的，主要特点是使用状态变量的概念并强调矩阵代数和主要在时间域进行分析和设计。
Rom was typically used for program storage in special - purpose applications , leading to the appearance of the computer numerical control ( cnc ) system , cnc was successfully introduced to practically every manufacturing process 只读存储器作为在特殊用途应用上程序存储器的代表，数字计算机控制系统随之出现，数字计算机控制系统成功地进入到所有制造业的生产过程中。
The digital electronic computer was invented on the forties of the 20th century in the west by the promoting of the urgent needs of social and military , and the development of electronics 是西方工业革命和科研促进了数字计算机有关的机械化数学思想方法在西方的发展，是社会和军事的迫切需要与电子科学技术的飞速发展，使得数字电子计算机最终于20世纪中叶在西方发明。
Seismic exploration data processing is a course that aims at field data processing by means of digital computer in order to obtain the information of subsurface structure and formation , which can be used for searching for petroleum and natural gas effectively 地震勘探数据处理是研究如何对地震勘探野外资料利用数字计算机进行处理，以获得有关地下构造和地层性质的信息，以便有效的寻找石油和天然气等矿藏的一门学科。
It has an advantages of low modek good robustness , strong adaptation and is applicable for the control of digital computer . it may acquire the better control quality if adaptive inverse control based on neural network applies to industrial process control 具有对模型要求低、鲁棒性好、自适应能力强、适用于数字计算机控制昆明理工大学硕士学位论文中英文摘要的优点，将之用于工业过程控制中可以取得较好的控制品质。
Along with the simulation theory , the method and theapplication engineering research is unceasingly thorough , as well as computer technology development , the application digital computer carries on the simulation to theactual system or the imaginary system more and more to be valuedpeople ' s 随着仿真的理论、方法和应用技术研究的不断深入，以及计算机技术的发展，应用数字计算机对实际系统或假想的系统进行仿真越来越受到人们的重视。
Discrete fourier transform is a special word for computers to fourier transform , so dft is adapted for computers to caculate . fast fourier transform is a kind of method to decrease the time used in dft . matlab makes matrix and vector as basic data unit 离散傅立叶变换( discretefouriertransform )并非泛指对任意离散信号取傅立叶积分，而是为适应计算机作傅立叶变换运算而引入的一个专用名词，所以dft是适用于数字计算机计算的ft 。
