直线系

直线加速系中的引力场及其经典近似

Gravitational Field in Linear Accelerated System and its Classical Approximate

本文研究的重点是减少计算时间，首先应用周期性边界条件，将计算区域始终限制在一个光子晶体元胞内，对于非正交结构的光子晶体，采用了非正交直线坐标系。

First , periodical boundary condition is used to make space domain in a photonic crystal unit cell , and for non-orthogonal crystal , non-orthogonal coordinate system is adopted .

直线匀加速参照系&兼论双生子佯谬

Uniformly accelerated frame of reference as its application on the twin paradox

在所有相互作匀速直线运动的坐标系中，自然定律都是相同的。

All laws of nature are the same in all c.s.moving uniformly , relative to each other .

正如沃弗森教授所指出的，相对论的精髓可以浓缩成一句话：在所有相互作匀速直线运动的惯性系中，物理定律具有相同的形式。

As Professor Wolfson points out , the essence of relativity can be summed up in a single sentence : The laws of physics are the same for all observers in uniform motion .
