Research on the Optimization of Oral English Teaching in Junior High School in the Environment of Man-machine Dialogue

Dumb English is a serious phenomenon among most teenagers in China. When the assessment system of man-machine dialogue is added to the entrance examination, English listening and speaking ability becomes indispensable to students. How to arouse teenagers' interest in spoken English and effectively improve their listening and speaking ability is very critical. The main learning environment for students is the classroom, hence classroom teaching plays a key role in enriching students' ability of listening and speaking. In view of the problems existing in junior high school classroom and students' listening and speaking ability, the relevant optimization strategies are presented.

A Study on the Problems and Countermeasures of Oral English Teaching in Rural Junior Middle Schools under the Background of Man-machine Dialogue Examination in China

English is a main subject of high school entrance examination in China. Many Students have learned English for more than ten years, but they are still unable to communicate with others in English after they graduate from middle school or even high school because of the poor oral English. With the advocacy of the new curriculum reform and quality-oriented education, many provinces and municipalities in China have introduced oral English test into the English exam of high school entrance examination. However, comparing with urban students, students’ oral English in rural areas is relatively weak, which is undoubtedly a huge challenge for rural junior middle schools. Hence, rural junior middle schools need to take measures to improve the oral English of students. This paper analyses the problems of oral English teaching in rural junior middle schools from the aspects of teaching facilities, teachers and students, putting forward some suggestions accordingly.

Integrated planning and the design of urban agglomeration: Bernhard Hafner's Comparative Simulation of Alternative Urban Prototypes

Cybernetic simulation programs that renewed the development process of urban agglomerations began to emerge as part of a paradigm shift that took place in the 1960s. During this period, changes in urban planning evolved in the context of cybernetically-informed research methods, in which architects and systems scientists focused on the environmental control of social and cultural planning processes. As such, the urban fabric became an object of planning and regulation. These events in turn generated the need for ‘big data’ processing in architecture. Consequently, the reconfiguration of urban architectural fabric emerged as a topic of scientific operation.In this context, in 1967, the Architecture Machine Group developed ‘Urban 5’, a planning program for urban participation based on man-machine dialogue. In the late 1960s, systems scientist Jay Wright Forrester also developed ‘Urban Dynamics’, a computer simulation exploring the interdependence of urban population, housing, and industry in the urban fabric. It was in this same 1967 environment that the Austrian architect Bernhard Hafner began to work autonomously, and without any personal relation to the other two projects, on a program for the ‘Comparative Simulation of Alternative Urban Prototypes’, based on the assumption that the design of urban forms had to be accompanied by the simulation of fields of urban dispersion.

A Virtual Instrument System for Determining Sugar Degree of Honey

This study established a LabVIEW-based virtual instrument system to measure optical activity through the communication of conventional optical instrument with computer via RS232 port. This system realized the functions for automatic acquisition, real-time display, data processing, results playback, and so forth. Therefore, it improved accuracy of the measurement results by avoiding the artificial operation, cumbersome data processing, and the artificial error in optical activity measurement. The system was applied to the analysis of the batch inspection on the sugar degree of honey. The results obtained were satisfying. Moreover, it showed advantages such as friendly man-machine dialogue, simple operation, and easily expanded functions.

Design and Implementation of Software for Quartz Crystal Feeding System

The paper mainly introduced the working process of automatic feeding system for quartz crystal laser marking, elaborated the human-computer interaction and control software design and implementation. System used double CPU system to control the mechanical parts movement and to send the laser marking control signal, and to conduct the man-machine dialogue. At first, the system realized the main function such as structured programming, reasonable allocation of system resources, and the software anti-interference design. Eventually system realized the automatic feeding and laser marking of quartz crystal, and was favorable to the effective management of the equipment operation personnel, and to meet the requirements of the user.

Research for Uniformity of Insulation Layer on Communication Cable Online Testing Control System

With the feathered development of communication and networks,the needs for the communication cable is highly increased,while the assurance of the communication cable’s quality is an important work for every cable factory to slove.The major research of this project is aim at the problems about the dynamic testing and the uniformity of cable insulation layer,and then the online test control system were designed.The control is mainly use OMRON's CS1G-H PLC as the central control system, at the same time control system uses touch-screen to realize the man-machine dialogue,which can effectively monitor the operational status of the equipment.Through the programming, simulation, simulation experiment for this system in the laboratory,proved that this system can be in motion, achieve the desired functionality. At the same time this system can be used for the promotion and use.

VB-Based Simulation of Four-Bar Linkage

The man-machine dialogue can be effectively realized by developing the animated simulation of four-bar linkage with VB. In this paper, through the analysis of linkage graphics, the animation flow chart of four-bar linkage is drawn.
