However, tillage enhances soil penetration, mineralization and eluviation, resulting in lose of soil organic matter and NO3-N, subsequently reducing soil carbon accumulation.

但翻耕后，土壤孔隙度和通透性增强，土壤的矿化作用和淋溶作用也增强，导致了有机质的矿化损失和NO3-N淋溶损失，减少了土壤中C的积累量。

But because of tillage, soil penetration is enhanced, mineralization and eluviation are also enforced, resulting in lose of soil organic matters and NO3-N by mineralization or eluviation, at last reducing the absorption amount of carbon in the soil.

但由于草地翻耕后，土壤孔隙度和通透性增强，土壤的矿化作用和淋溶作用也增强，导致了有机质的矿化丧失和NO3-N淋溶丧失，减少了土壤中碳的吸收量。

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。
