译文：这个仪器的工作原理是，当物质的分子由于加热、通电等而引起振动时，每种物质产生一种独特的光谱；在研究了此种情况下收集到的光谱后，Hilderbrand 宣布这种气体是氮。

这个句子的基本骨架是用and连接的两个并列的主句：This instrument works on the principle和after studying the spectrum,Hilder reported the gas to be nitrogen.第一个主句有一个用that连接的同位语从句，说明主句中的principle，而这个同位语从句又有一个用that连接的同位语从句，说明主句中的principle,而这个同位语从句又有一个用when连接的时间状语从句。第二个主句中包含了一个用which连接的定语从句，说明spectrum.
