对天然彩色棉纤维结构的初步分析发现，天然色彩存在于纤维次生胞壁内，发色基团与羰基有关。
The existence of carbonyl group in structure seems to be a factor that favors the formation of quasi-molecular ion (QMI) or other adduct molecular ion (OAMI) in positive mode.
化合物结构中羰基的存在似有利于化合物在正离子模式下形成准分子离子或其它分子加和离子。
Generally, the heavier the relative molecular mass, the higher the content of aromatic structure or the higher the content of carbonyl group, the more stable the emulsion is.
一般情况下，馏分的相对分子质量越大、稠环芳香结构和羰基含量越高，则乳状液越稳定。
