| 摘 要： | 雹云识别是一个多参数的模式识别问题。应用物元可拓思想将单参数雹云识别的不相容性转化为相容性问题。通过构造雹云和雷雨云两类样本的经典物无降节域物元，根据计算出的待识别云体与两类样本云体之间的关联度大小，进行雹云识别。该方法用于成都地区雹云识别结果的正确率达85％以上。

| Abstract: | Hail cloud recognition is a pattern recognition problem of multiMparameter. The recognition result of hail cloud based on single parameter is always nonMcompatible. The basic thinking of matter clements and extension set was used for changing the nonMcompatible problem into compatible problem. On the basis of designing the classical matter elements matrixes and the extensional matter element matrixexes of hail clouds and thunderstorm clouds, the recognition model of hail cloud is presented according to the magnitude of correlation degrees calculated between the clouds to be recognized and the two kinds of sample clouds. The accuracy of hail cloud recognition in Chengdu by this method is over 85%. |
