摘要将一种新的流形距离作为相似性度量测度，提出了一种用于无监督分类与识别的人工免疫系统方法。通过基于流形距离的相似性度量，有效利用样本集固有的全局一致性信息，充分挖掘无类属样本的空间分布信息，对样本进行类别划分。

By using the multi-year series of the circulation indices P and C for the closed pressure system on the unit radius spherical surface,three characteristic quantities of annual system centers(around the climatological center C-) are defined.1Average distance r,which is defined as the weighted geometric average distance of the annual system centers C deviating from the climatological center C-(i.e.the center location anomaly C′),is a measurement for distribution area of the system...

用单位半径球面上闭合气压系统环流指数P、C的多年序列，构造了历年系统中心在C-周围分布的3个特征量：1平均距离r，它定义为历年系统中心C偏离于气候中心C-的权重几何平均距离，是系统中心分布区域大小的度量；2压缩系数μ，它描述了历年系统中心分布区域偏离于圆形的程度，是历年系统中心位置分布各向异性的度量；3极大异常方向β，它用系统中心极大异常偏离-C处正东方向的角度，给出了系统中心的主要异常方向。

To some special ones...aquarius always be prone to keeping distance, because in his heart it's not the best thing to become couples just for the human needs...so to the special one, he always hope that the relationship between them should be last forever, once they go beyond the friendship limit, maybe some day, their affection will fade....then...how pity it will be...for the sake, aquarius would rather look at him/her silently at a long distance than fall in love with him/her, only by which their relationship can last forever....

对于有些人，瓶子始终是舍不得，舍不得因为男女之情跟他在一起。因为这个人，瓶子觉得跟他的相处应该是一辈子的事情，如果真的成为男女朋友，也许哪一日，感情褪色而分手。那样，该多遗憾。于是，瓶子宁愿永远这样默默的看着他，地老天荒，却无声也无言。我觉得后边的解释。。。更像是说，喜欢保持距离。。。so。。。。
