说明：  数学建模就是根据实际问题来建立数学模型，对数学模型来进行求解，然后根据结果去解决实际问题。当需要从定量的角度分析和研究一个实际问题时，人们就要在深入调查研究、了解对象信息、作出简化假设、分析内在规律等工作的基础上，用数学的符号和语言作表述来建立数学模型。
(Mathematical modeling is based on the actual problems to establish mathematical models, mathematical models to solve, and then according to the results to solve practical problems. When it is necessary to analyze and study a practical problem from a quantitative point of view, people should use mathematical symbols and language to establish mathematical models on the basis of in-depth investigation, understanding of object information, making simplified assumptions and analyzing internal laws.)
