摘要
用递归相似理论对１９９３年５月５日发生在甘肃省金昌市的一次特大黑风暴过程作了跃变分析，该理论中的跃变定义为身前数个状态不能完全表达当前状态的程度。计算结果表明，５月５日１６时（北京时）气象要素场的剧烈波动并不是递归分析中跃变的大值区，大值区主要出现在１６时之前。该文最后提出形式突变与本质突变两个新概念。
The subject is to study an example of special sandstorm occurred in Gansu province with recursive similarity.The jump was defined as the level that the preceding numbers of R data could not completely describe the present state.The results indicated that every element violent wave at 16 o′clock was not the larger jump value in recursive similarity,the larger values were occurred before 16 o′clock.At last,The formal abrupt and essential abrupt were presented.
