摘　　要：用局部结构熵算法对实际地震数据进行了计算和分析,发现局部结构熵算法若取小的分析体,虽然结构物图像的高频信息分辨能力得到改善,但却丢失一些宏观较大范围的主要信息,为了克服这种缺陷,该文首次在计算结构熵中引入了位置惩罚判据,这样不仅可以通过调整参数得到所需的更加清晰的结构物图像,获取大尺度的结构和小尺度的细节信息,而且提高了运算速度,在很大程度上提高了图像的分辨率。In this article, the authors calculate and analyze the actual seismic date with employing the algorithm of 3 - D local structural entropy. They discover that if they take the small date cube, although the geological structural image＇s resolution has been improved, some major and macroscopic information has lost. In order to overcome this blemish, the authors of this article introduce the location punishment criterion into the algorithm of structural entropy for the first time. In this way, they can not only get the more clear structural image, the large -scale structure and small -scale detailed information through adjusting parameters, but enhance the mathematical speed and improve the image＇s resolution to a large extent.
