标题： Doubly Special Relativity

摘要： 我简要地给出了近期关于“双特殊相对论”工作的非技术性回顾，“双特殊相对论”是一种相对论理论，在惯性观察者之间的旋转/洛伦兹变换由两个观察者无关的尺度（熟悉的velocity尺度，$c$和一个新的观察者无关的长度/动量尺度，自然被识别为普朗克长度/动量）所表征。我强调了与寻找宇宙射线悖论解决方案相关的一些方面。 显示英文摘要

摘要： I give a short non-technical review of the results obtained in recent work on "Doubly Special Relativity", the relativistic theories in which the rotation/boost transformations between inertial observers are characterized by two observer-independent scales (the familiar velocity scale, $c$, and a new observer-independent length/momentum scale, naturally identified with the Planck length/momentum). I emphasize the aspects relevant for the search of a solution to the cosmic-ray paradox.
