腐殖质的

These things in the topsoil that were once alive are called humus.

表土中这种曾是活体的东西叫做"腐殖质"。

It is rich in humus and slightly acid, due to leaching of lime.

富含腐殖质，微酸性，是比较好的农业用土壤。

The results show that total N, Cl(superscript -), organic matter, humic acid content of soil improves under vinasse treatments. Catalase and polyphenol oxidase activity increase abnormally at sugarcane settling stage and then sharply decrease to CK2 level at sugarcane maturity stage.

结果表明：蔗地施用废液提高了土壤全氮、Cl、有机质、腐殖质含量，使甘蔗苗期土壤过氧化氢酶和多酚氧化酶活性异常升高，随后迅速下降，成熟期下降到接近或小于CK2的土壤酶活性水平。

The results show that total N, Cl-, organic matter, humic acid content of soil improves under vinasse treatments. Catalase and polyphenol oxidase activity increase abnormally at sugarcane settling stage and then sharply decrease to CK2 level at sugarcane maturity stage.

结果表明：蔗地施用废液提高了土壤全氮、Cl-、有机质、腐殖质含量，使甘蔗苗期土壤过氧化氢酶和多酚氧化酶活性异常升高，随后迅速下降，成熟期下降到接近或小于CK2的土壤酶活性水平。

The mechanism for methylation of mercury in presence of humic substances was studied.

4对腐殖质存在下汞非生物甲基化作用的机理进行初步探讨。

During thawing period, its soil water changes as season changes (the dynamic rule of soil water has the important relation of the season): from June to July the quality-moisture content of soil water gradually increases and reaches the highest, and from July to August it begins to decreases. The range of the quality-moisture content of the ground litter and humus layer is lower than the illuvial horizon whose quality-moisture content is gradually increasing in this thawing season.

在土壤冻土融化期，草类落叶松林土壤水分存在明显的季节性变化，土壤枯枝落叶层、腐殖质层质量含水量比淀积层质量含水量变化幅度大；6～7月份土壤含水量逐渐增加，达到最高；8月份以后土壤含水量开始降低；土壤淀积层质量含水量保持逐渐上升趋势；坡顶土壤质量含水量明显小于坡底土壤质量含水量。

Mycetes in tunnel mainly come from outside and grows in humus in tunnel and increasingly pollutes more places.

坑道内的真菌主要来自于外界进入和坑道内部大量腐殖质繁殖，并逐步扩大污染范围。

3 Larvae stages of Postosia brevitarsis Leiwis overwinter in dung of cow, sheep, and pig with rich humus.

以2~3龄幼虫在腐殖质丰富的牛、羊、猪粪中越冬，未见有成虫越冬现象。

The humus properties and mineral composition of clay have the distinct features of zonality.

腐殖质性质及矿物组成具有明显的地带性烙印。

Our focus in composting is to create humus.

我们的重点在堆肥是为了创造腐殖质。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
