摘　　要：对肠道压力数据进行分形特性的分析,通过对结肠压力数据进行预处理,采用盒维数计算正常受试者和异常受试者结肠压力数据的分形维数.结果表明,该方法基本能够区分正常的和异常的结肠压力信号,可以作为判断肠道动力性能的辅助手段.The fractal characteristic of colonic pressure data is analyzed through box dimension. After pre-processing the colonic pressure data, the box method is applied to calculate the fractal dimensions. Through the fractal dimensions data are classified as the normal and abnormal, which accords with the original diagnosis. Experimental results show that the above method can serve as an assistant diagnosis of the colonic motility and can contribute to further research of the colonic motility based on pressure data.
