| 摘 要： | 讲相对论时学生已具有伽里略变换协变性和线性代数的知识，因此在工科物理中由洛伦兹变换协变性出发讲相对论动力学是可行的。教学的重点和难点在于如何让学生相信，相对论粒子的动量必须用四维动量来表达。

| Abstract: | It is able to teach relativity dynamics by Lorentz transformation covariance in engineering physics, since the college students have learned Galilean transformation covariance and linear algebra already, when they studied relativity theory. The emphases and difficulty in teaching is how to make students believe that momentum of a relativistic particle must be expressed by 4|dimension momentum. |
