In this paper, taking one 1900t/h supercritical pressure once—through boiler installed in East boiler company as subject investigated, analyzing the structure and characteristic of unit, from the mechanism of units, based on the law of quality conservation, energy conservation and momentum conservation, having Lagrange fluid particle tracing idea in hydrodynamics field application in analyzing of unit operational characteristic, author build up the nonlinear distributed parameter general dynamic mathematical model of single-phase heating surface or diphase heating surface in the steam-water system for supercritical pressure once—through boiler, which is suitable numerical calculation and simulation for large scale disturbance and full working conditions change, and enough materializing distributed characteristic of thermodynamic parameter in process and time lag characteristic of energy transportation in tache. The transient responses curve of the system main variables under several disturbance are computed by Computer Simulation for the model, and theoretical analysis shows that the simulation results are reasonable.

本文以东方锅炉集团公司的一台1900 t /h超临界压力直流锅炉为研究对象，在分析机组结构和特性的基础上，从机组的工作机理出发，以质量、能量、动量守恒定律为依据，将流体力学领域中的Lagrange流体质点追踪思想用于机组运行特性的分析上，建立了适用于超临界压力直流锅炉汽水系统单相、双相受热面的非线性分布参数通用动态数学模型，该模型适合于大扰动全工况变化的数值仿真计算，充分体现了过程热力参数的分布特性和环节中能量输送过程的时滞特性，并对模型通过计算机仿真得出各种扰动下系统主要变量的响应曲线，从理论上分析了仿真结果的合理性。

And why the financial tsunami furniture enterprises of Guangdong such a tremendous impact, root causes, the foundry dependent overseas brand is the drawbacks of the largest such enterprises in this kind of "superiority" against the background of the market, except as federal, red apples, dynasty and a small number of first-class enterprises to maintain a clear development strategy, the overwhelming majority of the owners of a strong sense of satisfaction, enterprise weak, and many companies willing to do for others is only "awake" so that process Zhejiang School of Gary Coull, who ho Lee so that the whole camp Kawasaki friend who Shuanghu, or impressive, or quietly deep secret agents, outflanking the Guangdong faction of the majority of the non-market-oriented camp, resulting in Guangdong Furniture today the so-called "overseas markets are also fast and slow overseas markets also "dual-Ren situation.

而为何金融海啸对广东家具企业造成如此巨大的冲击，究其缘由，依附海外品牌的代工是此类企业最大的弊端，在这种&优越&的市场背景下，除了像联邦、红苹果、皇朝等少数一流企业保持着清醒的发展战略外，绝大多数老板们满足感强了，进取心弱了，不少企业甘于只为他人做&嫁衣裳&，让浙派的顾家工艺、利豪们，让川派的全友、双虎们等，或有声有色地、或悄悄地深耕细作，包抄了粤派所不注重的广大市场阵营，造成了今天粤派家具的所谓&快也海外市场，慢也海外市场&的双仞局面。

Sensors, data acquisition cards and virtual instrument software are applied in the electronic control of ethanol injecting for optimized diesel/alcohol dual-fuel engine, through complement factor experiment which combines three fuel supply advance angle with four ethanol supply time, the performance of dual-fuel engine is compared with the original one under same condition.
