摘要我已经翻译了，不过本人对自己的英语水平不是太自信，希望有英语方面的高手帮忙看看，如果是直接由有道之类软件翻译的，就不必麻烦了。 中文及英文内容如下： 本文采用了MATLAB语言，建立了半干法烟气脱硫工艺物性参数数据库。研发的数据库主要由基本物性参数、热力学参数、传递参数、相平衡数据、反应动力学参数五个子系统组成： (1) 基本物性参数子系统由纯物质基本物性参数、混合气体基本物性参数、溶液基本物性参数三部分组成，提供烟气脱硫过程中涉及的烟气、脱硫剂、脱硫产物、水等物质基本物性参数的查询、回归、调用和输出。计算结果可以以数据、表、图的方式输出。 (2) 热力学参数子系统由纯物质热力学参数、混合气体热力学参数和相界面热力学参数组成，提供烟气脱硫过程中涉及的烟气、脱硫剂、水的比热容、焓、熵等热力学参数以及混合气体的pVT方程的计算。相界面热力学参数由气液相界面参数和液固相界面参数组成，提供固体的溶度积常数和气体亨利系数的查询与调用。 (3) 传递参数子系统由纯物质传递参数和混合气体传递参数组成，提供密度、黏度、热导率、表面张力、扩散系数等传递参数的计算。纯物质的传递参数来源都为可靠的数据或者回归方程，混合气体的传递参数的计算方程采用了多种常用的经验方程，在计算结果给出的同时，也向用户提供各方程的计算式，供用户参考。 (4) 反应动力学参数子系统建立了半干法烟气脱硫反应模型，并讨论了进口烟气温度、进口SO2分压、脱硫剂粒径等操作条件对脱硫效率的影响，并与不同实验值进行了比较，讨论了模型的可靠性。模型的计算结果可以数值的形式输出，方便调用，也可以图的形式输出，方便观察判断各因素对脱硫效率影响的趋势。 本文主要探讨了数据库的结构、数据库子系统MATLAB程序的编写、数据库的调用等内容。数据库可以提供对烟气脱硫过程进行设计、操作、模拟、优化所需的参数，为半干法烟气脱硫过程中参数的查询、过程设计和过程的操作优化涉及参数的调用提供了条件。 关键词：半干法，烟气脱硫，数据库，物性参数，MATLAB Abstract A physical parameter database for semi-dry flue gas desulfurization(FGD) process was set up by using programming language MATLAB in this paper.

Abstract A physical parameter database for semi-dry flue gas desulfurization(FGD) process was set up by using programming language MATLAB in this paper. This database includes basic property parameters, thermodynamical parameter, phase equilibrium parameterstransmission parameters and reaction kinetics（kinetic） parameters. (1) Basic property parameters database includes basic property parameters of pure substances, gas mixtures, （去掉逗号）and solutions. This database provides the basic property parameters of flue gas, desulfurizer, desulfurization product and water in flue gas desulfurization process. The calculations can be output as the forms of data, tables and figures. (2) Thermo dynamical parameters database includes thermo dynamical parameters of pure substances, mixture and interphase. The database provides thermo dynamical parameters of FGD, desulfurization products and water in flue gas desulfurization process, （与上段有点重复，建议换种表达形式，读起来更专业些）such as the calculated results of specific heat capacity, specific （去掉）enthalpy, specific （去掉）entropy and pVT properties. Parameters of interphase include solubility product constants and Henry's coefficients. (3) Transmission parameters database includes transport parameters of pure substances and mixture. The database provides transmission parameters of FGD, desulfurization product and water in flue gas desulfurization process, such as the calculated results of density, viscosity, thermal conductivity, surface tension and diffusion coefficient. Each calculation（result） is computed by common equations（empirical equations ）. The equations are given with the results. (4) The model for semi-dry FGD reaction process was set up in（by） the reaction kinetics parameters databases. The in different temperature of flue gas, pressure of SO2（SO2 pressure ）, dimensions of desulfurizer were discussed, and the consequence of the modeling was proved to be effective by comparing with the results of the experiments. The consequence of the modeling can be output as the forms of data and figures, which can show the trend of the effects of desulfurization. The structure of the database and the realization of each sub database was discussed in this article. This database provides parameters which are required in the operations, experiments, process modeling and optimizing of semi-dry FGD. Keywords: Semi-dry, FGD, database, physical parameter, MATLAB 还要注意的时态要一致，这个就楼主自己修改一下。 |
