Abstract : considering the special burning situation inside industrial furnace firebox ， an infrared calculation model with elimination of the influence of flue gas was established 2 - dimensional temperature patterns of furnace tube temperature in operation was obtained with infrared thermovision ， which provides scientific basis for the optimization of process operation 文摘:针对工业炉内特殊的燃烧环境，从消除烟气影响切入，建立了红外计算模型，并利用红外热像仪获得运行状况中炉管表面二维温度场及其变化特征，为优化工艺操作提供了科学依据。
The paper mainly simulates the producing process of tubes of small diameter , medium diameter and big diameter . it uses a terminational simulation method to study the producing capacity of these three types of tubes , the using rate of the machines and the occupying state of the machines " buffer - ins of the production line 论文针对小口径、中口径、大口径的高压锅炉管的生产过程进行终止型仿真，得到精整线加工这三种型号钢管的加工能力，各机组的利用率，各机组输入缓冲区的占用情况。
Petri net is good at reflecting systems " logical relationship and suitable to conduct time . it can also model systems on variable logica levels and now is used the most in modeling fms . the paper develops a petri net model of the high - pressure boiler tube production line in baosteel tube branch and a simulator of this system based on matlab / stateflow Petri网擅长反映系统中的逻辑关系；便于引入时间因素；能在不同的抽象层次上为系统建模，是目前柔性制造系统建模中采用最多的方法之一，本文建立了宝钢钢管分公司高压锅炉管精整线的petri网模型。
It testifies that chaos is existed in the sonic signal of boiler tube leak , according to the chaos theory and the correlative contents about the sky dynamics , and illustrates the physical meanings of the lyapunov exponent ( the change at the place of the boiler tube leak ) , based on the calculational methods of the lyapunov exponent and the peculiarities of boiler tube leak detection and diagnosis 根据混沌理论与空气动力学的有关理论，确定了炉管泄漏声信号中存在着混沌，在讨论如lyapunov指数的算法的基础上，针对锅炉炉管泄漏检测与诊断的特点，明确了lyapunov指数的实际物理含义(炉管泄漏点处状态的变化) 。
Based on the analysis and summarization about the hardware and the diagnosis theories of the no . 1 and no . 2 boiler tube leak monitor and diagnosis system , the design optimization is studied , and the experiments and theories about boiler tube leak detection and diagnosis are realized through the chaos and fractal theory ; the develops and designs of boiler tube leak detection and diagnosis system are finished , and acquire some good benefits 在分析、总结第一、二代炉管泄漏监测系统的硬件及线性诊断方法的基础之上，进行了炉管泄漏检测与诊断系统的优化设计，采用混沌与分形理论对锅炉炉管泄漏检测与诊断进行了理论与实验的研究；完成了炉管泄漏检测与诊断系统的设计与开发，该系统已成功地应用于实际，并取得了很好的效果。
