生物發(fā)生的,生物成因的

Biogenetic reefs were mainly distributed along the north continental shelf and slope of the Proto-South China Sea. 該期僅在古南海北部陸架和陸坡地區(qū)具備形成生物礁的條件。

The sample analysis showed that the nature gas at this area belonged to methane biogenetic gas. 氣樣組分分析表明,該區(qū)天然氣屬甲烷型生物成因氣。

This is going to occur due to biogenetic engineering that really has nothing to do with you. 這是即將要出現(xiàn)的，由于生物遺傳工程學沒有什么同你一道做的。

This situation provides a great oil and gas exploration potential of the biogenetic reefs in the South China Sea. 上述情況決定了南海盆地生物礁具有很大的油氣勘探潛力。

The possible biogenetic ways of diterpenoids from genus Euphorbia were also presented.Meanwhile, the research of this genus in future was prospected. 本文還就大戟屬中二萜類成分可能的生源代謝途徑提出了假設，并對該屬未來的研究進行了展望。
