一、前言数学模型的建立,就是运用数学方法去解决工程问题。所以数学方法的运用正确与否,必然关系到数学模型的成败。如果使用错误的数学方法,这个数学模型就会变得毫无价值。于仲洁同志所作“高炉碳砖炉底热侵蚀的研究”一文(发表于《武钢技术》1978年第4期,以下简称于文),是尝试应用数学模型解决工程问题的一个例子。这篇文章后来又摘要成“碳砖炉缸炉底热侵蚀的数学模型”一文,在《钢铁》1980年第9期发表。这无疑是十分可贵的,将有助于促进工程界利用数学方法说明工程现象,取得设计参数和解决工程问题。然而,在于文一再发表之后,个人经过反复推敲,觉得其中所用的数学方法,
First, the preface The establishment of mathematical models, is the use of mathematical methods to solve engineering problems. Therefore, the use of mathematical methods is correct or not, necessarily related to the success or failure of the mathematical model. If you use the wrong mathematical method, the mathematical model will become worthless. The article “Study on the Thermal Erosion of BF Briquette Bottoms” by Comrade Zhong Jie (published in “Wuhan Iron and Steel Technology” No. 4, 1978, hereinafter referred to as Yu Wen) is an example that attempts to solve the engineering problems by using mathematical models. This article was later summarized as “a mathematical model of the hearth thermal erosion of carbon brick furnace”, published in “Steel”, Issue 9, 1980. This is undoubtedly very valuable and will help to promote the use of mathematical methods in engineering to illustrate engineering phenomena, to obtain design parameters and to solve engineering problems. However, after the text was repeatedly published, the individual after repeated scrutiny that the mathematical methods used therein,
