计算机系统导论课程改革探索(英文)

In the paper,we analyzed the teaching problems in the course of "Introduction to Computer Systems",proposed guidelines with teaching practice and implement bilingual teaching.Then we explored the reform ways in the course of "Introduction to Computer Systems",to enhance students' self-learning ability through the full use of networked multimedia tools;and also the improvement of the teaching level of teachers.

Research on the reform of English writing teaching mode and its system construction under the background of information age

Today’s society has entered the information age, people’s thinking and learning methods have undergone great changes. This brings opportunities and challenges for the College English Writing Teaching. Based on the large background data in order to analyze the main problems of traditional college English teaching of writing based on proposed the idea of the University Teaching of English Writing from teaching objectives, teaching resources, teaching methods, students and life and relationships, and evaluation system. With the development of society and the times, the traditional English teaching model can not meet the needs of students. They urgently need to learn academic English knowledge for the future professional learning and research in the basic culture of academic quality. On the current status of teaching academic English at home and abroad, the author proposes a set of academic English writing class build system, and by way of comparative tests to verify the effectiveness and practicality of the system. We analyzed domestic and composition of the English examination system intelligence related applied research, put forward the theory of Constructivism basis, writing intelligent examination system to practical tools, built on Teaching of English Writing English Writing intelligent examination system so as to promote English writing teaching reform, autonomous learning ability to improve students’ English writing skills

Galerkin Finite Element Study on the Effects of Variable Thermal Conductivity and Variable Mass Diffusion Conductance on Heat and Mass Transfer

This article investigates the effects of variable thermal conductivity and variable mass diffusion coefficient on the transport of heat and mass in the flow of Casson fluid. Numerical simulations for two-dimensional flow induced by stretching surface are performed by using Galerkin finite element method(GFEM) with linear shape functions. After assembly process, nonlinear algebraic equations are linearized through Picard method and resulting linear system is solved iteratively using Gauss Seidal method with simulation tolerance 10^(-8). Maximum value of independent variableη is searched through numerical experiments. Grid independent study was carried out and error analysis is performed.Simulated results are validated by comparing with already published results. Parametric study is carried out to explore the physics of the flow. The concentration increases when mass diffusion coefficient is increased. The concentration and thermal boundary layer thicknesses increase when ?_1 and ? are increased. The effect of generative chemical reaction on concentration is opposite to the effect of destructive chemical reaction on the concentration.
