为了展示Tomato leaf curl Bangladesh病毒完整基因组上的微卫星分布特性。借助MATLAB软件、应用最优完全子图算法，提取并展示NCBI数据库中Tomato leaf curl Bangladesh病毒完整基因组（AF_188481.1）上的微卫星分布特性，计算1-碱基组至6-碱基组在完整基因组序列上重复出现的次数和位置，展示它们的分布规律（指数函数）。结果表明：Tomato leaf curl Bangladesh病毒完整基因组（AF_188481.1）上各种N-碱基组（N取1至6）最大的重复出现次数，随N按指数函数数减少；笔者提取和展示Tomato leaf curl Bangladesh病毒完整基因组序列微卫星分布特性（特别是微卫星各种N-碱基组重复出现的位置和次数）的方法，可以系统地运用到其他病毒完整基因组序列微卫星分布特性的提取和展示中，从而为有效利用微卫星分布特性研究完整基因组的结构和功能、遗传和变异规律提供完备、仔细的数据支撑。

In order to display the microsatellite distribution characteristic in the complete genomes of the Tomato leaf curl Bangladesh virus, with MATLAB software and the optimal complete subgraph algorithm, this paper extracted and displayed the microsatellite distribution characteristic in the complete genomes of the Tomato leaf curl Bangladesh virus (AF_188481.1) in the database NCBI and calculated the repeat numbers and locations of the N-bases group, then displayed their distribution disciplines. The results showed that: the law of exponential distribution had been simulated. The study provided theoretical basis for the control of the Tomato leaf curl Bangladesh virus. This research method was commonly suitable for the sequence analysis of various virus genomes.
