A method for mathematical modeling of the BOD-DO dynamics of a river is described. The method is applied to field data collected on Tu Men River in North-Eastern China. In this model of Tu Men River quality the functional structures of the deoxygenation coefficient k1, reaeration coefficient k2 and BOD sedimentation-resuspension coefficient k3 are established and tbe parameters determined by a regression technique to suit the characteristics of a river in the mountain area of North-Eastern China. In the model the sedimentation-resuspension coefficient k3 is given in the form of a single analytical function of the flow rate in the river. The model can also be used as basis for a river quality management scheme to be carried through on Tu Men River.

本文讨论了河流中BOD—DO动态的数学模拟方法,并将该方法应用于图们江,利用在图们江上取得的实测数据建立了江中BOD—DO动态的数学模型。在所得到的模型中,耗氧系数κ_1,复氧系数κ_2,BOD沉淀-再悬浮系数κ_3被表达为流量与水温的函数。表达式中的参数通过系统识别与参数估计方法确定,因此能较好地反映河流的地理环境特点。特别是κ_3的表达式,它以流量为自变量,用一个单一的解析函数同时描述了江中的沉淀与再悬浮现象,具有独创性。 本文所提出的BOD—DO动态模型可以做为图们江水质规划与管理的基础。

The numerical modeling of a two-dimensional pulverized coal flame, stabilized by a high temprature gas jet (nitrogen plasma jet), is proposed by using the integral method. Based on a Lagrangian treatment of the particle phases, the concept of a dilute suspension and the devolatilization and heterogeneous reaction models suggested by reference [3], the integral equations of gas and particle phases are deduced. After introducing approximate gas profiles and submodels of the particle processes had been established...

The numerical modeling of a two-dimensional pulverized coal flame, stabilized by a high temprature gas jet (nitrogen plasma jet), is proposed by using the integral method. Based on a Lagrangian treatment of the particle phases, the concept of a dilute suspension and the devolatilization and heterogeneous reaction models suggested by reference [3], the integral equations of gas and particle phases are deduced. After introducing approximate gas profiles and submodels of the particle processes had been established a system of simultaneous ordinary differential equations, which can easily be solved by conventional numerical methods and computer technics. It can be shown that with some modifications proposed method could be used for mathematical modeling of different cases of pulverized coal combustion, gasification, including coal-fired MHD combustors.

The detailed processes and procedures established by the auther for computer mathematical modeling on thermodynamical functions of metallur- gical reactions and the program design using FORTRAN Ⅳ language have been presented in this paper. Also the program list and two calculation examples have been shown. This computer mathematical modeling and the program can be applied to rapidly calculate thermodynamical functions of different kinds of reactions at any temperatures. When formulae, coeffi- cients of materials taking place in the reactions and reaction temperatures are read into computer, the results of calculations can be immediately obtained, which will be displayed out on the CRT or printed out by the printer.

本文叙述了笔者建立冶金反应热力学函数的电算数模及其FORTRANⅣ程序设计的详细过程和步骤,并列有程序清单(PROGRAM LIST)和两个计算实例。计算时只要将参加反应的物质的分子式及其在反应式中的系数、计算温度读入计算机,便可瞬间得到整齐漂亮便于阅读的打印结果。由于本程序成功地解决了相变温度的自动判断及按温度区间不同而进行积分运算的处理问题,故对任何反应任何温度下的计算均可适用。通过多个反应各种温度下的手算比较,证明了利用本程序进行计算的准确性和适应性。
