Otherwise the slices are ordered by lexicographicordering of their identifiers (which is a heuristic, but definite, ordering).
否则，这些片会按其标识的字母顺序进行排序(虽然是试探式的，但的确是一种排序)。

Hence, though the natural ordering of slices had "Mary" from the first slice, it is "Bill" who appears first in the resulting list due to lexicographicordering on their names.
因此，如果根据片的自然排序，来自第一个片的应该是“ Mary ”，但在这个结果列表中首先出现的却是“ Bill ”，这是由于它们是按照其名称的字母顺序排序的。
