谁能帮忙解释一下Lorentz symmetry

它跟广义相对论有什么关系? 急！！！！

前面是个人的名字，后面时镜像。也就是说，这个Lorentz镜像是解释许多物理定律的一个假设。也就是所有的物理定律对于静止观察者是一样的。
It was Einstein who, in 1905, first used Lorentz symmetry to describe the laws of physics in our universe. He took Lorentz symmetry as a postulate of special relativity, whereby he assumed that the laws of physics - including the speed of light in a vacuum - are the same for all inertial observers. An inertial observer is anyone with a system of calibrated clocks and rulers that is at rest in a frame of reference that is not accelerating. Einstein worked out the consequences of Lorentz symmetry and came to the startling conclusion that measurements of length and time intervals are different when they are made by inertial observers moving relative to each other. The extent of this distortion of space and time is described by a set of equations that are now known as Lorentz transformations (see "Lorentz and CPT symmetry" in Further information).
