摘　　要：理论力学课程所涵内容丰富,往往教师花费较多的精力和时间,但教学效果却不理想。本文提出了理论力学中的定理、定律的表示符号是一种推理性符号,认为理论力学中符号具有能指和所指基本要素,体现了理论力学中形式层面和意义层面这两个层面的对应关系。两个层面的结合具有任意性和动机性,任意性保护符号编码不受任何类比的影响,动机性使记忆变得容易。理论力学中符号是一种具有意指作用的科学编码,认为其符号是随意的意指类型和形象的意指类型的综合体现。借助符号语言进行理论力学教学,可帮助学生正确理解公式各物理量之间的联系,提高教学效果。Theoretical mechanics course is rich in contents. So it usually takes teachers a lot of time and energy to teach students. However, the teaching results are not as good as expected. In this paper, it is brought forward that all symbols and signs used to express theorems and laws in theoretical mechanics are reasoning scientific codes. These symbols and signs possess two basic factors-signifier and signified. They indicate two corresponding relations from two perspectives. One is formed level layer and the other is meaning layer. Their combination has the features of random and motivation. The feature of random protects coded signs against the influence of any other analogy, and the feature of motivation makes them be easily memorized. The symbols and signs in theoretical mechanics are a kind of scientific codes which possess meaning function. They can be seen as a comprehensive expression of random meaning type and image meaning type. With the help of symbolic language, teachers can help students better understand the inherent connection of different physical quantities and improve the teaching effectiveness simultaneously.
