连接的从句不同
so that：so后边可加形容词或副词。
such that：such后要用名词
如果such后边的名词是由many、much、few、little等词修饰的话，则不用such，而使用so。
so that：so是副词，与形容词或副词连用，其结构是so+adj.(adv.)+that从句。
such that：such是形容词，它所修饰的名词可以是可数名词，也可以是不可数名词名词前面可以带形容词，也可以不带。如果其后是单数可数名词，前面需加不定冠词a或an。

such that: 如此…以致Their cost structure is such that they just can't compete with the low-cost carriers.

so that such as such that的区别
首先区分such as和另外两个短语。such as的作用是举例，意思是“例如”，如：You can see many animals， such as tigers and lions.
而so…that…和such…that…这两个连词短语的作用则是连接结果状语从句，意思是“如此…以致于…”。区别是so后面加形容词或副词，而such后面加名词。
