The paper focuses on literatures abroad of the use of one networked technology, namely synchronous computer-mediated interaction, in the second language (L2) classroom. The scope is intentionally limited to research concerned with evaluating the potential benefits of computer-assisted classroom discussion (CACD) in terms of second language acquisition (SLA) theory. It is suggested that in addition to analyzing language outcomes by means of well-motivated measures of L2 use and L2 acquisition, a multiplicity of data sources be used in CACD research, so as to be able to document the processes learners actually engage in when interpreting and carrying out CACD tasks. A process- and task-driven research agenda for L2 CACD is proposed with the ultimate goal of describing the nature of language, learning, and interaction fostered in networked synchronous communication and to ascertain which features of CACD may or may not be relevant to the processes involved in second language acquisition.

This paper briefly introduces the importance of the enterprise asset management system for power plant, and presents the whole function requirements of the enterprise asset management. The system modeling method andprocess based on Unified Modeling Language (UML) is discussed, and the modeling process of the system adopts two steps: the first step is to recognize and ensure use cases and actors of the system;the second step is to build the static model and dynamic model of the system. The design scheme of the system is made up of use case diagrams, activity diagrams, class diagrams, sequence diagrams, and component diagrams. The scheme of the enterprise asset management system incorporating with UML technique offers the reference for the analysis and design of related information system.

Along with the rapidly advancement of the computer hardware and software technology, special-purpose simulationcomputer system has gradually failed to keep pace with the developing and application trend of simulation technology. So in its development process, simulationcomputer gradually got rid of the customization road, gradually choose a common path. KDRTS (Ke Da Real Time simulation System), which has been successfully used in hardware-in-the-loop (HITL) simulation experiment of certain guided weapon system, is a general real simulation system based on common personal computer hardware. This paper introduces composition of the hardware system, structure of the software system and expounds its characteristic of KDRTS in detail.

A computersimulation for safety tests, including material nonlinear, geometrical nonlinear and state nonlinear, under static loads of agricultural tractor's cab is completed. The simulationprocess was completed according to the rule 4 of OECD standard codes for the official testing of agricultural and forestry tractors. The test process of back push, back press, side push, front press and front push in static loads test of tractor's cab was simulated, and the absorbed energy, the distortion and the stability state under the static loads of tractor's cab was verified. The safety of tractor's cab can be judged in the design stage by using the computersimulation, some design mistakes can be corrected betimes and the loss due to dissatisfied to the safety standard of OECD can be avoided.

The technology of virtual reality is one of the most important simulation technologies in the world today for its effect and low outlay. A feasible method of the gymnastics movement and the arrangement in the environment of virtual reality is presented in the paper. The model of the gymnastics movement and the arrangement in a set is built by 3Dmax. A system for the movement and movement combination of gymnastics in a set is exploited by the computer virtual reality technique. This newly exploited system can visualize the movement combination process of gymnastics and make it editable. It can decrease the dangerous of the created difficult movement and extend the coach's arrangement space. Also, it makes a good preparation for further research of simulation of gymnastics movement.

The layout design of household electrical appliances belongs to NP hard problem of combinatorial optimization;it has to meet needs of different constraints, and consider the complexity of projects. Practice shows that Human-computer must develop their respective advantages to resolve this problem effectively. Parallel genetic algorithm of Human-computer cooperation was put forward in the paper to optimize layout design of household electrical appliances products based on researching of Parallel genetic algorithm. The algorithm put artificial individual and algorithm individual together to form solutions group. In the calculation process it achieved an effective method of intervention to prevent the defects occurred in algorithm by Human-computer interaction. Comparing the test, it showed that the parallel genetic algorithm using "Human-computer cooperation" solves the optimization problems of the layout design about household electrical appliances effectively.

The air drawing model of polyethylene terephthalate (PET) polymer and the model of the air jet flow field in spunbonding process are founded. The air jet flow field model is simulated by means of the finite difference method. The numerical simulation computation results of distributions of the air velocity and air temperature match quite well with the experimental data. The air drawing model of polymer is solved with the help of the distributions of the air velocity and air temperature measured by a laser Doppler velocimeter and a hot wire anemometer, respectively. The predicted filament fiber diameter agree with the experimental data well. It can be concluded that the higher initial air temperature can yield finer filament fiber diameter , and the higher initial air velocity can produce the finer fiber diameter as well. The experimental results show that the agreement between the results and experimental data is very better, which verifies the reliability of these models. Also, they reveal great prospects for this work in the field of computer assisted design (CAD) of spunbonding process.

Human modelling tools provide a means to perform virtual task evaluations upon designs within the computer environment. The ability to evaluate the accommodation of a design early on in the design process before physical prototypes can be built has many advantages. These advantages are particularly relevant in supporting people in attempting to design products that are inclusive and accessible. HADRIAN is a new tool developed to provide accessible, and applicable data on people with a broad range of size, age, and ability together with a means of optimising virtual task evaluations. This paper describes the use of HADRIAN in performing a task evaluation, focusing on the underlying methodology that aims to achieve a virtual simulation that mimics a real world user trial.
