思政教育在公共课中占有非常重要的地位,但如何针对大学生自身的特点,在公共课的讲授中潜移默化地融入思政元素,并与课程内容完美结合,确实需要任课教师进行深度思考.笔者作为公共课《大学计算机》的负责人,对于思政元素的教学融入方面有了一些探索和实践,取得了良好的效果.

分析目前教学内容和教学活动中的关键问题,提出将互联网慕课模式与传统面授模式相结合的混合教学模式,以C语言程序设计课程为例,介绍混合教学模式的实施方法和实现过程.

Numerical solution for hyperbolic systems has always been a hot problem because of its wide applications in the field of natural science.In this paper,nonlinear elliptic differential operator can be decomposed as linear item and nonlinear item for solving a class of nonlinear second order hyperbolic systems.The former is approximated by the implicit scheme and the latter is approximated by the explicit scheme.The method can turn nonlinear problems to the similar linear system with different right-hand side at each time step,while we have similar triple diagonal matrix on left-hand,it is easy to compute and the scheme is absolutely stable.The Alternating-Direction Schemes can turn multi-dimensional problem into one-dimensional problem and Iterative matrix of x,y are triple diagonal matrices which have same structure,so they are easy to program for parallel computing.At last some numerical results are presented to prove theory analysis.

Mesoporous rare earth luminescence material with Ce was perapared by liquid-crystal template method using non-ionic P123 as the template,and the properties was characterized by FT-IR and fluorescence spectra.Reaction conditions were optimized by investigating the influence of different acidities of reaction systems.The results showed that when pH value of reaction solution was 0.4,the fluorescence intensity of sample materials reached the strongest level.

The finite difference scheme is devised for a class of the unstable nonlinear Schrdinger equation.Two discrete conservation laws of the difference scheme are proved.By using the energy method,the convergence and stability of the difference scheme are proved.

Image fusion is the combination of two or more images to obtain a new image of better quality using a certain algorithm.An energy minimization method which can fuse panchromatic image and multispectral image is proposed.The energy mainly consists of two components.One ensures the injection of more correlated detail spatial information.The other ensures the preservation of the spectral information.Additionally,prior knowledge about the high spatial resolution multispectral image and other constraints can also add to the energy.

数学建模是利用各种相关的数学知识,对实际问题进行分析和核心内容提取,建立起切实可行的数学模型,然后进行分析计算,最终得出一定的结论,应用到实际生活中。利用数学软件MATLAB对提出的实际问题进行建模,就可以使得人们从繁重的计算中解脱出来,把更多的精力投入到对知识的理解和应用之中,从而也大大提高了进行数学建模的效率。
