the technique of spectroscopy allows (analyst) of incoming light after it (has been) separated into (its) component wavelengths (by passage) through a prism.

allow的用法是allow sb to do sth,这里将analyst改为analysis也不符合这个用法啊？passage这里是名词？

cyclamates were introduced in the early 1950's (as) alternative sweeteners (for) use (by) (individuals) who needed (reducing) their sugar intake for medical reasons.

need 后面也可以加doing吧？

analysis 不是 somebody(sb)！所以不是你提的 allow sb to sth

analysis是"分析"的名词

analyst是分析员。
