摘要: 洛伦兹变换是狭义相对论的核心内容.理解并掌握其内含的时空变换规律,对进一步理解狭义相对论时空观具有十分重要意义.本文基于时空图的二维旋转变换,从几何上对洛伦兹变换中所包含的“钟慢尺缩”时空变换本质和光速不变性等条件进行解析.使学生能够更加直观去感受并理解洛伦兹变换,为后续课程学习打下基础.

Abstract: Lorentz transformation is the core content of special relativity. It is of great

significance to understand and master the conceptual connotation of Lorentz transformation

for further understanding the space - time view of special relativity. In this paper,the

nature of time-space transformation called clock slowing and scale reduction and the

speed of light invariance condition are studied based on the two-dimensional rotation of the

space-time dia- gram. It enables students to understand the Lorentz transformation more

intuitively and lays the foundation for subse- quent courses.

Key words: college physics, classroom teaching, special relativity, Lorentz transformation, two-dimensional rotation transformation
