这基本上是一个嵌套结构，它只是给出了每个产品在源文本中匹配的字符偏移量。

Basically, this is a nested structure that simply gives the character offsets where every production was matched in the source text.

根产品(“para”)取得成功并结束于偏移量289处(源文本的长度)。

The root production (" para ") succeeds and ends at offset 289 (the length of the source text).
