Detailed spectroscopy of one of the polymers (PDMS) suggests that chemical reactions may be involved, as many oxidized derivatives of the polymer were detected.

通过对其中一种聚合物进行详尽的光谱分析表明，可能发生了化学反应，观测到了聚合物的氧化产物。

Swain says just four extrasolar planets' atmospheres have been studied in detail with spectroscopy, a chemical analysis technique. Another 32 or so have been observed.

斯温说，在太阳系以外，只有四个行星的大气层被光谱分光镜技术(一个化学分析技术)仔细观察和研究，还有32个曾被观察到。
