Digitalstromkreis haben eine grenze . w & auml ; hrend man die industrieautomation erreicht , sind viele signale analoge signale . man mu & szlig ; die digital - analog umwanden , um digitalstromkreis dieses （ analoges signal ） zu verarbeiten 数字电路有局限性。因为在实现工业自动化过程中，很多信号都是模拟信号，为了用数字电路处理这些模拟信号，必须模数转换。
Modern mechanic equipment is becoming more and more complicated , automated and intelligent , so the importance of rapid diagnosis and maintenance technologies is obvious which ensure the security and reliability of the manufacturing system 现代工业自动化过程日益复杂，自动化和智能化程度也越来越高，因此确保系统安全、可靠运行的诊断和维护技术显得尤为重要。
Made up with a low - power - consumption x - ray tube , proportional counters , preamplifiers , amplifiers , ad converters and multichannel analyzers , an xrfa system is economical and practical and is widely used on scientific research and industrial automatic process control 由低功耗x光管、正比计数器、前置放大器、主放大器、 ad变换器以及多道分析器组成的系统是经济、实用的x荧光分析系统。它在科学研究和工业自动化过程中得到广泛的应用。
The application of image segmentation is very extensive , especially in the information society nowadays , using computer technology to carry out the automation process of the vision information processing makes it almost appeared at all relevant fields of image processing , and that involves various image types 其研究多年来一直受到人们的高度重视。图像分割的应用非常广泛,尤其在信息社会,通过计算机实现视觉信息处理的自动化过程,使得它几乎出现在所有有关图像处理的领域,并涉及各种类型的图像。
At present , it was applied to different industry , depended on information technology , we can realize automatic operation for process base on manual work and the functions of computer , and can also realize different degree of automatization ( manual operation , semiautomatic , automatic ) for the management of operation by applied workflow technology and workflow management system that have well adaptability 在这样的背景下，工作流技术得以产生，并有了巨大的发展，并在不同的行业中得到了应用。工作流管理技术和工作流管理系统得到广泛重视的一个重要原因是它能够在信息技术的支持下实现基于人工和计算机活动组成的业务过程自动化，可以实现不同自动化程度(人工操作、半自动化、自动化过程)的规范化业务管理功能，具有良好的适应性。
