摘　　要： 在狭义相对论的框架下,文中首先论述了在时空间隔保持不变的条件下,惯性系之间的时空变换一定是线性的,随后证明了在这一条件下惯性系之间的时空变换必定也是唯一的,最后证明了这唯一的时空变换就是洛伦兹变换.因此从时空间隔保持不变这一条件出发完全可以建立洛伦兹变换,文中在最后一节还论证了这一建立洛伦兹变换的条件是最基本的条件,没有其他更低的条件. In the framework of special relativity, it is first proved that the space-time transformation between two inertial coordinate systems is surely linear if the space-time interval keeps invariant in all inertial coordinate systems. It is demonstrated that this space-time transformation is unique yet; it is finally justified that the unique space-time transformation is certainly Lorentz transformation. Therefore, the Lorentz transformation can he established according to the condition of that space-time interval keeping invariant. In the last part of this paper, it is proved that the condition of that space-time interval keeping invariant is the most basic condition of establishing Lorentz transformation, there are not any conditions which can establish Lorentz transformation as well as.
