In order to quantitatively analyze the characteristic and development economics of eco - industrial systems , the ecological resource acquisition , conversion , and transfer within a bounded network of processes are characterized and monetarily priced mathematically in terms of the principles of material and energy balance 摘要为了定量地刻画生态工业系统特征过程，建立一组基于物质和能量守恒定律的数学方程，分析了带有边界的生态工业系统与自然（工业）资源相互获得、交换、或转换的过程。

We are having a group of professional and experienced overseas and local engineering , project management , equipment fabrication and servicing team , providing our clients professional process consultancy , space management and detail engineering , equipment fabrication , site installation , commissioning and after sales service 本公司专业于水处理系统、废气处理、气流处理系统和其他主要的工业系统，如反渗透水、去离子水、高超纯水、废水、排风、冷却水、排放液、废气洗涤塔、制程真空、清扫真空和设备机电二次配。
In the past 20 years , b & wbc was awarded consecutively as “ excellent foreign invested enterprise in beijing with advanced technology ” , “ top 100 biggest enterprise in china ministry of machinery system ” , “ excellent foreign invested enterprise in beijing ” , “ top 100 foreign invested enterprise in beijing ” , “ top 10 excellent foreign invested enterprise in beijing ' s industry system ” , “ beijing advanced technology manufacturer ” and “ merit of national labor day ” , etc 二十年来，北京巴威公司凭借自身的优势和坚韧不屈、勇往直前的精神，先后荣获全国“外商投资先进技术企业” 、机械系统“百家最大工业企业” 、北京市“优秀外商投资企业” 、北京市“经济百强生产型外商企业” 、北京市工业系统“十佳外商投资企业” 、北京市“先进技术企业” 、 “全国五一劳动奖章”等多项荣誉。
When facing to complex , dynamic and nonlinear systems , it is usually hard to analysis the mechanism of processes and to build up mathematic models , or it will take us unbearable costs . in most situations a nonlinear system has special properties that are different from the others , so we ca n ' t find out just one or few methods suitable to model and control all those nonlinear systems 然而，工业系统的结构、参数和运行模式在不断的变化，对过程机理的透彻分析和精确数学模型的建立常常需要付出无法接受的代价，系统的控制和故障诊断也就因此面临一个精确建模问题。
With the idea of the open engineering system , using the hail for workshop of metasynthetic engineering ( hwme ) , intelligent control techniques , the expert system and the design of experiments are integrated within the framework of the nonlinear multi - objective decision support system to develop a robust , top - level design specification so as to make the system have the quality of adaptive control , self - organizing , self - learning and robustness 该方法利用综合集成研讨厅体系，提出满意解集概念，把控制模型、专家系统、智能控制技术、仿真程序和实验分析综合在非线性多目标智能协调系统的框架中，探索设计空间，形成一个开放的稳定的设计，充分体现了把生态工业系统设计成一个开放的工程系统的指导思想，并使这个设计系统具有自适应、自组织、自学习和鲁棒性的特点。
With the developing of modern technology , especially with the speedy developing of computer technology and network communication technology , industry system has been become bigger and bigger , and will further progress to integrated automation system mode , which is wide field interlinking , intelligent diagnosing and remote monitoring . these changes cause the structure of modern equipment become more complex , and the coupling of components become worse increasingly 随着现代工业技术的发展，特别是计算机技术、网络通讯技术的飞速发展，工业系统的规模越来越大，并进一步向广域互联、智能诊断、远程监控的综合自动化系统模式发展，这使得现代设备的结构越来越复杂，设备及设备的零部件间的关联耦合程度日益加剧。
