m阶B树中“阶”的含义

http://en.wikipedia.org/wiki/B-tree#Terminology

B树的阶(英语对应order)定义是不统一的：
Unfortunately, the literature on B-trees is not uniform in its terminology (Folk & Zoellick 1992, p. 362).
Bayer & McCreight (1972), Comer (1979), and others define the order of B-tree as the minimum number of keys in a non-root node.
Folk & Zoellick (1992) points out that terminology is ambiguous because the maximum number of keys is not clear. An order 3 B-tree might hold a maximum of 6 keys or a maximum of 7 keys.
Knuth (1998, p. 483) avoids the problem by defining the order to be maximum number of children (which is one more than the maximum number of keys).
