在力学课程教学中，通过引入Dirac函数，可以方便地对力学中的集中力、集中力偶矩以及瞬时脉冲力等物理量，以连续分布的形式加以统一地表达和解决。在介绍Dirac函数的定义、基本性质以及物理背景的基础上，给出了Dirac函数在力学课程教学中的典型应用。Dirac函数在材料力学、结构力学和弹性力学课程中的教学示例，体现了力学教学过程的多样性。

In the mechanics course teaching, using Dirac function can easily express the concentrated force, concentrated couple, instantaneous pulse force and other physical quantities in a continuous distribution in a form of uniform. Based on the definition, basic properties and physical background of Dirac function, the typical applications of Dirac function in the mechanics course are given in the paper. Using Dirac function in the teaching of material mechanics, structural mechanics and elastic mechanics reflects the diversity of mechanics course teaching.
