摘要: 利用二维闵氏时空图解析双生子效应.明确闵氏几何线元长度与质点的固有时成正比,利用时空图中比较世界线长短的方法直观地在不同参考系中对双生子效应进行了定量的分析.另外,对"三生子佯谬"进行了定性半定量分析.

关键词: 闵氏几何, 时空图, 双生子佯谬, 固有时

Abstract: Two dimensional Minkowski space-time diagram is used to analyze twins effect. Clearly, natural Minkowski geometry line element length is proportional to the proper time of a particle;the space-time diagram comparing the world line length directly in different frames of reference is also used to analyze quantitatively the twins effect. In addition,the "three twin paradox" are qualitative and half quantitative analyzed.

Key words: Minkowski geometry, space-time diagram, twin paradox, proper time
