Aromatic rings can be joined at a pair of adjacent carbons to yield compounds such as naphthalene, anthracene and chrysene. 芳环能在一对相邻碳上结合，生成萘、葸和?傅然0合物。
The contents of anthracene, acenaphthene, benzo(a)anthracene, and chrysene were much higher than that of any other compounds. 含量较高的化合物主要是蒽、荧蒽、苯并 (a)蒽和?等 .
Benz(a)anthracene and chrysene neither induced MCF-7 cell proliferation(P>0.05) nor increased rat uterine weight(P>0.05). 苯并 (a)蒽和 1,2 -苯并菲既不能导致大鼠子宫湿重明显增加 (P >0 0 5 ) ,也不能诱导MCF - 7细胞增殖 (P >0 0 5 )。
The ubiquity of phenanthrene series, chrysene series compounds, perylene and retene compounds in the sediment indicated that PAHs mainly came from the terrestrial plants. 在样品中检测到角鲨烯，表明这一地区存在生物甲烷合成和细菌作用，具有生成油气及天然气水合物可能性。
When these two techniques were combined with the resonant synchrononus spectrofluorimetry,the detection limits of chrysene,anthracene and perylene can be improved 13.2,24. 3 and 67 times respectively. 二者结合起来用于同时测定屈、蒽、苝，检测限改善近67倍。该法相对标准偏差小于2．7%25。
