Rapd （隨機擴增多態性dna ）技術是二十世紀90年代發展起來的一項dna分子多態性檢測技術，它建立於聚合酶鏈式反應（ pcr ）技術基礎之上，利用隨機合成的寡聚核苷酸序列為引物（一般為10個bp ） ，分別與dna的兩條單鏈結合，在dna聚合酶的作用下，對基因組的特定區域進行pcr擴增，其電泳結果為不同大小和數目的dna譜帶即rapd圖譜，可反映基因組相應區域的dna多態性。One is the " belt persistence ", which is defined as the total length of joints teace length in a 1m wide belt projected to a basic line ( eliminating the overlay section ) over the length of the basic line. another is the one called as " search persistence ", which is defined a as the total length of joints trace length on the searched potential slipe surface over the length of the slip surface. thus, the author establishes a measuring and calculation system to these definitions and finishes a great deal of field investigation aiming at the joints trace length and the " rock bridge " survey
