相对论性电子在随机小尺度磁场中的辐射称为抖动辐射。我们利用抖动过程来研究GRB瞬发辐射的偏振特征。我们的模型采用了一个包含随机磁场的二维压缩板。在满足抖动条件的情况下，当视距与平板平面夹角较小时，可以实现高度偏振。此外，还考虑了具有微射流结构和射流离轴效应的微发射器。
The radiation of relativistic electrons in random and small-scale magnetic field is called jitter radiation. We apply jitter process to study the polarization feature of GRB prompt emission. A two-dimensional compressed slab which contains stochastic magnetic field is applied in our model. If jitter condition is satisfied, the high degree polarization can be achieved when the angle between line-of-sight and slab plane is small. Moreover, micro-emitters with mini-jet structure and jet off-axis effect are considered.
