数学模型是针对某种事物系统的主要特征、主要关系等,用形式化的语言概括地表达出来的一种数学结构。数学模型要靠数学概念或数学符号来描述。在利用数学模型方法求解数学问题时,通常会出现以下两种情况:1.由实际问题抽象出来的数学模型恰好是某个已知条件的一部分,可以利用已有的数学知识推导出要求解的数学结果,有利于学生的实际操作能力的培养。2.由实际问题抽象出来的数学模型没有在已知条件中显现,要通过逻辑推理建
The mathematical model is a kind of mathematical structure which is expressed in a formalized language for the main features, main relations, etc. of a certain system of things. Mathematical models rely on mathematical concepts or mathematical symbols to describe. The following two situations usually occur when solving mathematical problems by using mathematical models: 1. The mathematical model abstracted from practical problems is just a part of a known condition, and the existing mathematical knowledge can be used to deduce the solution to the problem Mathematical results, is conducive to the cultivation of students’ practical ability. 2. Mathematical models that are abstracted from practical problems do not show up in known conditions and are to be construed through logical reasoning
