| 摘 要： | 马尔可夫(Markov)链理论是用来描述随时间(空间)变化的一个离散状态序列的状态转移特性的,本文将其引入来研究土壤剖面多环芳烃有机污染物的垂向变化规律,建立了基于空间离散化的马尔可夫(Markov)链理论数学模型及垂向归趋极限.研究结果表明,基于空间离散化的马尔可夫(Markov)链理论数学模型及垂向归趋极限能够很好地模拟区域土壤剖面多环芳烃(菲)的垂向变化特征,并有迁移规律的识别功能. |
| 关 键 词： | 马氏链 多环芳烃 菲 垂向分布 转移概率矩阵 |

| Abstract: | Markov chain theory can be used to characterize the transition of a dispersed state sequence changing with time or space.This paper establishes the mathematical model and the vertical fate limit of the space discretization based on Markov chain theory and studies the regulation of vertical changes of polycyclic aromatic hydrocarbons（PAHs）.The results show that the mathematical model and the vertical fate limit of the space discretization based on Markov chain theory can simulate the vertical migration of polycyclic aromatic hydrocarbons（PHE） in sewage irrigation region and have the ability to identify the migration rule. |
| Keywords: | Markov chain polycyclic aromatic hydrocarbons（PAHs） phenanthrene（PHE） vertical distribution transition probability matrix |
