(1)线性的结构：由数→式→方程和不等式→函数； This paper discusses the applications of idea and method of ordinary differential equations in middle school mathematics Typical material has been provided for the established viewpoint of the middle school mathematics of ordinary differential equations. 在常微分方程课程教学研究中 ,讨论了常微分方程的思想方法及在中学数学中的应用 ,对系统地建立常微分方程高观点下的中学数学 ,提供典型素材 Solutions of some indeterminate equations in high schools 中学数学里不定方程的解法 On how new century textbooks dealing with the contents of equations 谈新世纪版实验教材对“方程”的处理 The solving of inequalities has close relations with functions, equations, sequences, trigonometry, linear programming, solid geometry and analytic geometry. 解不等式与函数、方程、数列、三角、线性规划、立体几何以及解析几何等有着密切的关系。 geometry nature about how to lead the students to understand the geometry nature of circular cone with equations in the thought of figures and shape. 其中定义的教学探究主要是揭示圆锥曲线的本质特征,几何性质的教学探究主要引导学生从方程的角度,用数形结合的思想去理解圆锥曲线的几何性质。 In the method of calculation, the property of ellipse is used to build three equations to find out the size of major radius R and minor radius r of the ellipse, as well as the angle θ between the major axis and the X axis. 在计算法中,利用椭圆性质列三个方程,求椭圆长半径R与短半径r的大小以及长轴与X轴的夹角θ。 This paper deals with the initial and boundary value problem of linear heat equations. 本文研究线性热方程的初边值问题。 This essay exemplifies and discusses how mathematical means (equations, equation sets, functional limits, inequalities, image metholds etc) are used in working out problems in electricity. 对数学工具（方程和方程组、函数极值、不等式、图象法等）在解电学题中的应用进行了举例和探讨． The paper lists five types of solutions to some particular plane equations,expounding the impertant function of solutions to problems in teaching. 列举了一类特殊平面方程的五种解法 ,并分别阐明和强调各种解法在教学中的重要作用。 This paper chooses various parameters from different perspectives and gets different parametric equations. It is proved that all these different parametric equations can be changed into a same common equation. 本文从不同的角度分别选取不同的参数,从而分别得到不同的参数方程,但可以证明,这些不同的参数方程却可以化成同一个普通方程。
