It reviews the physics development before the birth of special relativity at the beginning of 20th century, and gives the important reasons why many famous physicists, such as Hendrik Antoon Lorentz, Henri Poincaré, failed to create a new theory, though they had already obtained some very important results, almost close to this great theory.
对20世纪初相对论诞生之前的物理学发展进行了回顾，分析了在1905年爱因斯坦发表著名的狭义相对论之前，物理学家如洛伦兹、庞加莱等人尽管已经走到了狭义相对论的边缘，得到了狭义相对论的一些结论，但最终却没能创建一个全新的物理学理论体系的深刻内因。

For the first time, we study the radio afterglow behavior during the trans-relativistic phase of the fireball shock wave. Considering the trans-relativistic shock dynamic and the synchrotron self-absorption effect of the relativistic electrons on the radio emission, we find that the dense medium model can not only explain the fast decline of the X-ray and optical afterglows of GRB980519, but also account for its radio afterglow quite well.
我们首次研究了致密介质情形下射电余辉在跨相对论阶段的行为，发现考虑到激波的跨相对论动力学和相对论电子的同步自吸收效应对射电辐射的影响，致密介质模型既可以解释GRB980519的快速衰减的X射线和光学余辉，也可以很好地解释其射电余辉的特点。

When the object motions are observed in different inertial frames, their conclusions of time dilation can be opposite; it indicates that, the experimental result of time dilation is different obviously from special relativity, and can not look upon the equivalent to the latter and testify its correctness.
从不同的参考系观察，它们的结论是可以相反的；因此，时间膨胀的实验结果与相对论是明显不同的，不应与相对论的时间膨胀效应等同起来，也不能用来证明狭义相对论的正确性。

The results show that:(1) The space-charge fields(include dc space-charge fields and ac space-charge fields) have important effect on the beam-wave interaction output power, make the saturated output power lower, saturated position delay;(2) The back-radio excited by the electron beam has little effect on the output power, and can be ignored;(3) The transverse motions of electron beam has some effect of the output power;(4) The means of phase velocity taped and bunch compression can improve the relativistic TWT efficiency, especially bunch compression can greatly improve the efficiency.
五、分析了相对论行波管三维非线性特性，分析结果表明：(1)空间电荷场（包含直流和交流空间电荷场）对注波互作用输出功率影响很大，会造成饱和输出功率减小，饱和位置推后；(2)电子注激发的反向辐射对输出功率影响比较小，基本上可以忽略不计；(3)电子注横向运行对注波互作用的直接影响比较大；(4)通过改变耦合腔内半径来调节慢波结构相速，采用相速跳变和预群聚的方法可以改善相对论行波管的效率，特别是采用预群聚方法，可以尽量提高相对论行波管的效率。
