常見例句Aromatic rings can be joined at a pair of adjacent carbons to yield compounds such as naphthalene, anthracene and chrysene. 芳環(huán)能在一對相鄰碳上結(jié)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. 含量較高的化合物主要是蒽、熒蒽、苯并 (a)蒽和?等 .Whereas benz(a)anthracene and chrysene can not inhibit the specific 3H -estradial binding to rat uterine estrogen receptor( P >0 05). 苯并 (a)蒽和 1,2 -苯并菲各劑量均不能明顯抑制雌二醇與雌激素受體的結(jié)合 (P >0 0 5 )。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 -苯并菲既不能導致大鼠子宮濕重明顯增加 (P >0 0 5 ) ,也不能誘導MCF - 7細胞增殖 (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. 在樣品中檢測到角鯊烯，表明這一地區(qū)存在生物甲烷合成和細菌作用，具有生成油氣及天然氣水合物可能性。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. 二者結(jié)合起來用于同時測定屈、蒽、苝，檢測限改善近67倍。該法相對標準偏差小于2．7%25。 返回 chrysene
