中文摘要：

来自脉冲星辐射束的中心和外围的成份一般分别称之为核成份和锥成份．前人研究发现脉冲星的核成份与锥成份的宽度之间有很好的0．7倍比例关系，并将此写入教科书．收集整理了33颗核、锥成份非常明显的脉冲星的观测数据，对这些脉冲星的积分脉冲轮廓进行高斯拟合和成份分离，从而得到核、锥成份的宽度及误差．分析了三峰和五峰脉冲星的核锥成份，发现核锥脉冲星其核和锥成份的宽度在统计上没有明显差别，并不存在前人发现的0．7倍的比例关系．

英文摘要：

The central and outer components from the radiation beam of pulsars are called core and conal components, respectively. It is found in some early researches that the widths of conal components are 70% of the widths of the core components for corecone pulsars. To confirm it, the 33 pulsars with significant conal and core components are selected. The components of the profiles of these pulsars are separated and fitted with Gaussian functions. The widths and errors of each conal and core component are obtained. The relation between the widths of the conal and core components for the triple-component and five-component pulsars are investigated, respectively. We find that the widths of conal and core components are not significantly different. There is no relation with a ratio of 0.7 between the widths of conal and core components of pulsars.
