生物發(fā)生的,生源的,產(chǎn)生生命的

The second period, from 1.25 Ma to 0.8 Ma, showed low biogenous mineral contents and represented a severe environment. 第三時(shí)期，四十八萬(wàn)年到八十萬(wàn)年前左右，生物源礦物的組成幾乎只有方解石，可反應(yīng)營(yíng)養(yǎng)鹽組成變化，而造成鈣質(zhì)殼體生物成為優(yōu)勢(shì)；

They have an established religion, the Harmony, and developed an eugenic program called Biogen. 他們信仰美好的（事物）他們發(fā)展了一種優(yōu)生學(xué)叫“初生代”。

The third period, from 0.8 Ma to 0.48 Ma, calcite was the major biogenous minerals instead of opal.It implied a different nutrient condition. 第四時(shí)期，約四十八萬(wàn)年以來(lái)的沉積物記錄大致可以與晚第四紀(jì)全球氣候十萬(wàn)年周期的變遷相呼應(yīng)。

In a sense, compliance with California will be easier for Biogen than for many other companies. 在某種意義上，遵守加州將生物更容易比許多其他公司。

This Paper compares deeply usual animal feedstuff additive with new type of feedstuff additive, a kind of a biogen. 文章將動(dòng)物常用飼料添加劑與新型飼料添加劑(活菌制劑)進(jìn)行對(duì)比討論。
