求翻译：定理2 表明, 如果两个知识表示之间存在包含关系, 而它们的知识的信息量( 或知识粒度) 又相同, 那么这两个知识表示是一样的, 即两个分类是完全相同的。是什么意思？

Theorem 2 shows that, if the knowledge that exists between the two inclusion relations, and their knowledge of the amount of information (or knowledge of particle size) and the same, then the knowledge that these two are the same, that is, two categories are identical.

theorems 2 shows that, if two knowledge that contains a relationship that exists between the volume of information and knowledge (or knowledge would be the same as particle size) and the two knowledge that is the same, that is, the two classifications are identical.

Theorem 2 suggests that if two containment relationship exists between knowledge representation, amount and their knowledge (knowledge or granularity) the same knowledge representation is both, namely two classifications are identical.
