摘要
利用组合数学中的递归关系给出了１９９４年全国大学生数学建模竞赛题Ｂ题关于锁具计数的新算法，锁具数的递归关系及通项公式，具有一般性．
By using the recursive relation in combinatory,a new algorithm on the problem of the lock counting in the B question of Mathematical Modelling Contest in 1994 is presented.The presented recursive relation and general form of the lock number have universality.
