Alkylbenzene, normal alkanes and alkylcyclohexane on the pyrolysates of P. Boryanum at 300℃ had uniform distribution and the relative content of them was similar, indicating that they originated from same precursors. Fatty acids, alcohol and ketone in algal cell are the possible precursors. For example, the precursor of relatively abundant C〓 alkylbenzene and alkylbenzene with C〓 side chain perhaps related with palmitic acid. N-alkylnaphthalene in pyrolysates at 300℃ probably derived from alkylation of cleavage products of aromatic steranes and terpanes.
在盘星藻300℃热解产物中,烷基苯、正烷烃和烷基环己烷碳数分布一致、各化合物的相对含量接近,表明它们有相同的来源,藻类体内的脂肪酸、醇和酮及细胞壁等物质可能是其母质,相对含量较高的碳数为16及侧链碳数为16的烷基苯类化合物,其前身物可能与软脂酸有关。300℃热解产物中的正烷基萘类化合物,可能由芳香甾、萜类的降解产物与直链烃类加成烷基化而形成。

The numerous macro-plants during the Doushantuoian were branching and semi-floated and erected on seafloor.

陡山沱期的宏体藻类多分枝并直立固着于海底,提高了光合作用的效率,增加了海中水体中的含氧量,不仅改善了环境,为依赖一定氧而生活、生长和繁殖的后生动物给予了必要的支持,而且作为生态系统中的必要基础,为宏体后生动物的快速发展和演化提供了一个新的食物源。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
