翻译成中文是何意思？我主要不明白 for which 的意思。

定语从句 which 是指代concepts (properties) 而for 是后面的动词所带的介词即provides for definitions will be discussed shortly 中的for 还可以放在介词后面Examples of theoretical concepts (properties) which network analysis provides for explicit definitions will be discussed shortly.如果有介词的话，用which作先行词时候，不能用that替换

WHICH指的是前面EXAMPLES...(PROPERTIES).
如果把定语从句拿出来,就是network anaylsis provides explicit definitions for the examples of theoretical concepts(properties)
