我们在这里讨论一种新的伽马射线暴(GRB)模型，该模型基于奇异恒星的差动旋转。该模型中的奇异星和Klu‘zniak-Ruderman模型中的差动中子星可以产生伽玛暴所需的极相对论、可变的火球，从而成为毫秒脉冲星.研究了这些脉冲星对爆发后火球通过磁偶极辐射膨胀的影响.我们表明，这两个模型不仅能自然地解释伽玛暴的各种特征，而且能解释余辉的光曲线.
We here discuss a new model of $\gamma$-ray bursts (GRBs) based on differentially rotating strange stars. Strange stars in this model and differentially rotating neutron stars in the Klu\'zniak-Ruderman model can produce extremely relativistic, variable fireballs required by GRBs and then become millisecond pulsars. The effect of such pulsars on expansion of the postburst fireballs through magnetic dipole radiation is studied. We show that these two models can explain naturally not only various features of GRBs but also light curves of afterglows.
