July 28, 2001 Computer and Application, Development of Manipulation Module for Operation Module of Chemical Unit Based on Person 1 Wang Xiaohong Lei Ming Zhao Wen Zhou Chuanguang School of Chemical and Pharmaceutical Engineering, Qingdao Institute of Chemical Technology. Qingdao 266042 developed the operation module of chemical unit operation. Users can watch the corresponding performance. It is clear that such important solutions as the cascade solution method to determine the number of theoretical plate layers of the rectifying tower in terms of phlegm moisture, and the physical meaning of important concepts, in order to deepen the understanding of the original operation of the chemical unit, and the dynamic performance of the interface Ask for the process.æ±´ has an open style; Therefore, there is barely flexibility. Suitable for undergraduate graduate students and engineering and technical personnel to learn to use.

1 lead 100 touch 28 is a platform-independent feature of the operating system that can run on fat 13., 8 95, 1052, U Tim, and View 3 and other operating systems. People 18 integrated the advantages of the interactive language and the object-oriented language, and the processing efficiency is hard to compare with other software. Its function can be said to be a set of reliable numerical calculations like image processing and high-level shape interface design style equal to the body, in addition it also provides interfaces with other high-level programming languages ​​such as 艮, which makes it increasingly powerful Since the content of many chemical unit operations is difficult to achieve the expected teaching results only through the description of the text4, it is necessary to add some formative content to assist learning. Therefore, we have to deal with the difficulty of each unit operation and play a role. Strong Receipt Date: 200009 Funded National Institute of Higher Education Teaching and Research Association, National Institute for Research and Education, National Center for Research and Research, Project Support Program, No. 3, Gejie Xie, Qiu Lun, Board of Experiments Feeding board farmers, stocking socks holding equipment, envy 6 distillation, dry performance is difficult to perform a large, based on the development of a chemical unit operating model based on the PCT 1 module. The module has the effect of the text, the user can easily select the relevant content to perform the performance, through interactive operation to achieve learning objectives. If the user has a certain knowledge, the progress reflects the open characteristics of the program, 2 the development and implementation of the operation module of the chemical unit 21 development environment 1 more than 586 computers, 8 Dui, above the graphics card. 5181 coffee. Sound card. 31 memory in software. Need to recognize 95 or more operating systems in Chinese, 殪197 and from 8, several software, 2.2 structure of the performance module 2.2.1 Performing the frame structure of the module Reliable absorption tower equipment and drying unit operation in the typical design and operation of the type, At the same time, a detailed description of the drawings was drawn, and the in-depth analysis of the questions and answers was made, and the corresponding information was provided to impress the users.

Heat transfer convective heat transfer process temperature distribution tower analysis 1 plate load performance distillation solution to determine the theory of distillation tower plate thousands of dry dampness and air state point to determine the maximum absorption rate and minimum liquid-gas ratio solution. Solve for the total number of units in the gas phase Pump line characteristics curve with the change in flow characteristics of the chestnut different connection characteristics of the curve absorption of fluid transport mechanical fluid transport operation of the model analysis Valve opening changes in the impact of the pump operation Supply and demand at the potential energy of the pump Effect of Operation Fluid Density Effect on Pump Operation Effect of Fluid Viscosity Change on Pump Operation Impeller Diameter Speed ​​Change Effect on Pump Operation Comparison of Series and Parallel Schemes of Pump Comparison 2.2.2 Formwork Interface Instructions for Use 1 Worker Pound No Operation Form Ching Lung , 儋 向 向 向 向 向 向 向 向 向 向 茳茳 茳茳 茳茳 茳茳 茳茳 茳茳 茳茳 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8. Each chapter is made into a module that can be played independently. Users can quickly switch between modules through the main interface.

For example, when entering the steam feeding module, Shell appears as a three-dimensional playing interface, using the previous step, and the next step, buttons to control the shape of the single-step speech. The shape of the playing window and the content of the text area correspond. Use the replay button to return to the initial state for the next performance, and the auto-play button automatically plays the various forms and corresponding text descriptions in sequence. Due to the open program of the program, the user 1 adds performance content according to his own requirements so as to meet the corresponding learning needs.

2.3 Program Design of the Performance Module 2.3.1 Production of Material in the Performance The produced text will be used in the following programming of the performance model.

We make full use of the powerful shape-drawing function of Heren 18 to make complex shapes. The shape of the shape will be used in the following program design.

The specific shape rendering is to make the value of 1's idleness 1 attribute value be completed. First of all, it is necessary to determine the change relation equation between the variable drill and the enthalpy variable. Within a given range, the profit and idle numbers are plotted. To distinguish the various lines. Over 1 function in the function. In the process of drawing the shape, it is found that the shape of the last drawing shape is always refreshed next time. In order to use several functions and one function, the design of the program must also be combined with the cycle and judgment statements. For example, the solution in the distillation unit operation determines the precision. Plotting of Theoretical Plate Numbers of Distillation Columns .

2.3.2 The design of the program is determined by determining the shape of the plant. The overall structure of the plant is followed by the structure of the text and the shape of the structure. The realization of each interface of this small module is achieved through the user interface function of the 8's. The user interface redundancy refers to a user interface composed of various types of objects such as a menu bar, a frame control button, and the like. In this user interface, the user's commands and the user's technical skills of the program are realized by selecting various cube-shaped objects. The children of the eight-cube cube-shaped objects are divided into two types of user interface objects and The user interface of the user community, where the design of the user unit object is designed to be effective, must select the appropriate form factor and organize them logically to make it easy to operate and use (1) with a wide interface.

The basic method of creating a control meta object is to use a function that recognizes 8 and the function is called in the form of uimntrolOrfig, an attribute name, an attribute value, and when designing a program, the necessary function name and attribute value may be provided to the function blood, 1 gamma 1 as required. Parameter pair.

Is the value of the window handle. The created control object will be a child of the window and appear in the window. The corresponding 7 static texts and 7 buttons in 2 are the control meta objects created. By calling other subroutines with attributes, the interactive functions of the buttons are realized.

Number, and then enter the corresponding text content and drawing shape in the text window and the command window respectively. After the order is added, the last file is saved as 1 and the corresponding file is called using the attributes of the shape control element. In order to achieve chemical unit operation function.

24 connection between the performance module and the operating environment This module is fully developed using 1 recognition language. The program code is stored as a river file. In the statement of the river file, another 1 file can be referenced, and it can also call itself recursively. The river file can be generated with any text editor and is a human 301-byte text file. Due to the limitation of the current version of 18, the operation of its program cannot completely separate from its environment, so it is difficult to compile its program into an executable file. Therefore, the operation of this module must be based on 18 languages ​​and 3 platforms. It seems that the interface is used to try to use 0 languages ​​to call subroutines. This can give full play to the advantages of the two and greatly increase their application. flexibility. And with the slight upgrade of the coffin, this question will inevitably get a good mole rattle, Chau, Gina oil such as 2.5, several people 8 people, 1 ice application due to the knowing of River Man 6 will successfully put The authors, 8, and Jia, and 97 and Person 8 are integrated into one entity. Therefore, the author runs the source program for calculating the theoretical plate number of the distillation tower in oil, and can watch the generation process of each curve in real time. The parameters of distillation column operation and design in the source program can be modified according to their own needs. The modified shape curve immediately changes, and the progress is reflected. Also, 1 The characteristics of interactivity and openness. 3 Conclusion Based on 28 languages. The difficulty in the operation of the chemical unit has led to the development of a performance-based module with a text-rich interface. The user can understand the physical significance of the important processing methods and important concepts by watching the corresponding performances, thereby deepening the chemical unit. Understanding of operating principles. Because of its open style, users can set the program according to their own needs Schrodinger.
