Originally developed for detecting air pullutants, a technique called proton-included X-ray emission,which can quickly analyze the chemical elements in almost any substance without destroying it, is finding uses in medicine,archaeology,and criminology。

这句话是正确的一句解释说WHICH指代地很正确

A technique originally developed for detecting air pollutants, called proton-induced X-ray emission, which can quickly analyze the chemical elements in almost any substance without destorying it

这句话是错误的解释说WHICH这个词出了逻辑性指代错误

两个WHICH前面的名词都是EMISSION 不过按照的说法其中一个肯定是指代了EMISSION而另外一个指代的是A TECHNIQUE
这是何解

第二个在pollutants和called当中插了那么巨大一个逗号啊，逗号后面called开始的插入语都可以ignore
