Abstract: This research focuses on integrated applications of tactic problem solving skills in dynamic reaction figures for Acid and Base chemical learning. It elucidates the strategic validity for major conceptions of reaction equations with ions and charge transmissions in chemistry which often let college students’ chemical learning get misconceptions and misunderstanding. This study takes experimental samples from the experimental group and the controlling group with total number 95 tenth-grade students. It integrates both quasi-experimental approach and statistic analyses for students’ learning achievements in problem-solving skills and satisfactory questionnaire. All fundamental base of this research would be summarized in the following way: (1) Experimental group students, who had mastered strategic skills of chemical dynamic reaction figures, had superior posttests learning achievements to those of controlling group students. (2) By comparisons between posttests and pretests, students in the same experimental group had more significant and increasing learning achievements of posttests in Acid and Base chemical unit of problem-solving skills than those of their pretests. (3) As for the performances of different dispositions of chemistry, experimental group students indicated more significant learning satisfactory attitudes, learning performances and over larger effect sizes in Acid and Base chemical unit. To sum up, students get many problem-solving skills from applications of chemical dynamic reaction figures which could be available approach for the validity and performances in chemistry learning.

Abstract: This work illustrates the application of the sinc-collocation method to the second-order linear hyperbolic telegraph equation in one-space dimension. The exponential rate of convergence makes this method useful for approximating the solution of this equation. Numerical results show the efficiency of this method.

Abstract: The virtual camera technology emerged in the field of three-dimensional animation and 3D movies. In recent years, it is being developed in the domestic. Virtual camera technology is particularly remarkable in the field of animation creation, and which can solve lots of complex and practical problems, such as the problem of low efficiency of works creation, the lacking of the sense of reality. This paper will provide a new design scheme for virtual camera system, using the special inertial senor to collect motion data of the virtual camera to realize the virtual roaming and shooting in 3D virtual scene. We will discuss the design principle of the virtual camera deeply and give an efficient implementation scheme in this paper.
