问一个句子的理解。。。

freesaUID: 2225142

Such variations in size, shape, chemistry, conduction speed, excitation threshold, and the like as had been demonstrated in nerve cells remained negligible in significance for any possible correlation with the manifold dimensions of mental experience.


杨鹏难句里面说，such as在这里是被分割的固定搭配，但是我从小到大只学过such as在一起用表示例如，这里拆开了，同时后面的定语从句的主语也没有了（看样子应该是前面的 variations），实在有点不明白了。。。

那位给解释一下吧。

as 引导定语从句，相当于that,所以后面没有主语

Such variations in size, shape, chemistry, conduction speed, excitation threshold, and the like (that had been demonstrated in nerve cells) remained negligible in significance for any possible correlation with the manifold dimensions of mental experience.

恩，as作为关系代词，这个解释比较合理：）
