本文在考虑了电子的自旋角动量与轨道角动量的耦合作用后，通过对Bohr理论中的电子运动角动量的修改，推导出单电子体系的电子速度公式，结合对Schrdinger的原子轨道能级表达式相对论效应修正，从而得出本文的氢及类氢离子光谱精细结构值的理论计算公式，应用此改进公式，所得的计算值与实验观测值符合得很好，计算结果也反映了氢及类氢离子光谱精细结构数据变化的规律性。

First, according to a phase matching condition of electromagnetic wave on the stationary boundary surface, we find the refelection and transimission angles in the front system with a static ionization front. Then using the transformations of wave vector and frequency we get the corresponding angles in the laboratory system in which the ionization front is moving at relativistic speed.

这种相变的发生是由于以相对论速度飞行的高能重离子在相互发生碰撞的过程中，巨大的粒子动能被沉积在核-核碰撞的有限区域内，并转化为热能，形成极端高温高密环境，迫使强子体系解禁闭，形成QGP新物质形态，并最终转化为末态粒子的产生。

Arthur Leonard Schawlow, for some time a professor at Stanford University but now deceased, showed theoretically that masers could be made to operate in the optical and infrared region and proposed how this could be accomplished in particular systems.

这个实验的精度是前无先例的，能测出小到10^-12的相对频率偏差，这更确凿地证实了七十多年前迈克耳孙-莫雷的实验结果，这个实验以及当时发现不久的穆斯堡尔效应，都证实了爱因斯坦的相对论理论。

Jesus probably had his first revelations while doing humdrum carpentry work. Einstein worked out his theory of relativity while serving as a clerk in a Swiss patent office. Machiavelli wrote The Prince and the Discourses while immersed in the dull life of a small country town where the only excitement he knew was playing cards with muleteers at the inn.
