巨脉冲是一种持续时间很短的射电爆发现象，它们的流量密度往往比平均脉冲大几十倍、百倍，甚至千倍以上，成为脉冲星射电辐射中最显著、最突出的现象。Crab脉冲星自发现以来一直受到广泛关注，它是极少数能够发射巨脉冲的脉冲星之一。射电巨脉冲轮廓形状、微细结构、能量分布的充分研究，对揭示脉冲星辐射机制和具体辐射过程有重要意义。

In 1968, astronomers serendipitously detected giant pulses from the Crab nebula, which is theoretically expected for a long period of time. Giant pulse is an astonishing and remarkably phenomenon in radio pulsar emission. It is a short-term radio burst, with flux density that can reach tens, hundreds or thousands times of their average pulse. Crab pulsar attracted extensive attention from its discovery, as it is one of the very rare pulsars that could emit giant pulses, It allows one to study giant pulse profile, microstructure, and energy distribution. Although the physical mechanism and generating condition of the giant pulses are still not well understand, the accumulating observational results and theoretical predictions will help us to built a coherent picture of these giant pulsars.
