实验室坐标系

主要工作是：具体研究火球所抛出壳层的相对论流体动力学演化，应用同步加速辐射机制，通过由共动坐标系到实验室坐标系的相对论变换，得到Gamma暴余辉的光变曲线。

The hydrodynamic evolution of the fireball shell is comprehensively studied . Using the synchrotron mechanism and relativistic transformation from co-moving frame to lab frame , the light curves of the gamma-ray burst afterglow are obtained .

在实验室坐标系中，载流中性导线的总体电荷线密度必然是零，同时在与形成电流的电子相对静止坐标系中总的电荷体密度必然为零。

In the lab frame the total linear charge density of a current-carrying wire must be zero , and while in the rest frame of the electrons making up the current the total volume charge density must be zero .

利用实验室坐标系磁Compton散射截面公式，对谱函数进行了更精确的计算。

Based on the cross section of the magnetic inverse Compton scattering in the laboratory reference frame , the spectrum function is recalculated .

通过把实验数据从实验室坐标系转化到质心坐标系，得到反应产物在不同质心角度下的平动能分布和角度分布。

Data measured in the laboratory frame were converted to that in the center-of-mass frame to obtain product kinetic energy distributions and angular distributions in the center-of-mass frame .

为获得相对于实验室固定坐标系的精确的模型姿态和位置测量值，必须在成像照片中有固定坐标系框架标志的清晰影像。

In order to obtain the accurate position and attitude of model related to a fixed coordination of laboratory , a clear photograph with fixed frame of coordination is needed .
