Based on the analysis and calculation of a chaotic strangeattractor produced by Lorenz equation, the paper states out a problem existed in the classical method of calculating the correlation dimension. Furthermore, some modifications and improvements on it are presented.%通过对洛伦兹（Lorenz）方程生成的混沌奇怪吸引子的分析计算，指出了相关维经典计算方法中存在的问题，进行了修正改进.
