论文摘要
Pulsar故障是Pulsar旋转频率（$ν$）的突然旋转。小故障大小$Δν/ν$是任何机制的关键参数。在本文中，以$Δν/ν= 10^{ - 7} $分配的小故障尺寸分布，$Δν/ν/ν/ν<10^{ - 7} $被视为小尺寸的小故障（SSG），而$Δν/ν/ν/ν/ν/ν> 10^{ - 7} $的尺寸尺寸为大尺寸的Glite（ls）。相似性。在与小故障大小混合物的脉冲星中，使用Lilliefore测试来识别此类脉冲星中SSG和LSG的分布模式。结果表明，尺寸分布的每一半彼此之间有根本不同。 LSG被认为是正态分布的，而SSG是对数正态的。
Pulsar glitches are sudden spin-ups in pulsar spin frequency ($ν$). The glitch size, $Δν/ν$, is a key parameter in any mechanism puts across towards the understanding of the events.However, the distribution of the glitch sizes has persistently been bimodal.This bimodal nature could be intrinsic or otherwise. In this paper, the glitch size distribution is bisected at $Δν/ν= 10^{-7}$ with $Δν/ν< 10^{-7}$ being regarded as small size glitches (SSG), while those of $Δν/ν> 10^{-7}$ are taken as large size glitches (LSG).The magnitude of SSGis scaled to that of LSG and tested for similarity.In pulsars with mixture of glitch sizes, Lilliefore test is used to identify the distribution pattern of SSGs and LSGs in such pulsars. The result indicates that each half of the size distribution is fundamentally different from one another. LSGs are seen to be normally distributed, while the SSGs are lognormal.
