Our finding shows that the light curve structure is correlated to the GRB duration.

这表明GRB的光变曲线结构与其持续时间有密切的关系，光变曲线的FWHM越宽，则持续时标越长。

在应用数学中，离散模型连续模型的离散近似。在离散模型中，离散方程are fit to 数据。使用递推关系是这种建模方式的一般方法。时标微积分是差分方程理论与微分方程理论的统一，应用在需要建立离散和连续同步数据模型的领域。

Our results show that with the up to date experimental data,〓C can not sufficiently burn, the neutron number density decrease, the timescale of neutron source become long and these come into conflict with model of Thermal Pulse AGB star.

研究结果表明，在新实验结果下，〓C不能充分燃烧，中子数密度降低，中子源持续的时标变长，这与热脉冲AGB星的现有模型出现矛盾。
