腐殖质

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。

But minable uranium deposits can hardly formed in this period because of absence of abundant uranium-rich groundwater and strong absorption of humus and magnalite.

然而这一阶段由于缺乏大规模富铀地下水的注入，以及腐殖质和蒙脱石强的吸附能力，故难以形成具有工业价值的铀矿床。

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。

Especially, sulfide has significant positive correction and negativecorrection with unsteady fractions (acid soluble fraction and reducible fraction)andsteady fractions (oxidable fraction and residual fraction)of Cu and Zn in MSW,respectively. Simulation computation results from Visual MINTEQ showed that Cu~(2+)was mainly associated with humus and migrated from lose association (FA_1-Cu) totight association (FA_2-Cu), while Zn~(2+) was mainly presented with complexation withS~(2-) which was strengthened as the reducing environmental surrounding in landfillgradually.

Visual MINTEQ模拟计算结果表明，渗滤液中Cu大部分为腐殖质络合态，并逐渐由与松结合态富里酸络合态(FA_1-Cu)向稳结合态富里酸络合态(FA_2-Cu)转变；Zn则主要表现为与S~(2-)的络合，其络合程度随模拟填埋场内还原性环境形成而加剧，生物反应器填埋场的渗滤液长期回灌能促使Cu和Zn逐步形成络合沉淀而使其在填埋垃圾内的迁移行为减缓。

The abundance of Sminthuridae in the XS11 plot was higher than that in the KMD plot during the first month after transplanting.

在大田生长前期XS11田间以圆跳虫为主的弹尾虫比KMD田间的高，中后期弹尾虫基本消失，主要原因估计为缺少腐殖质来源：A89BC论62文网www.abclunwen.com

Based on research of frozen soil status in quo and analysis of earlier results of highway tympanites nation and abroad, taking advantage of the project"The tympanites mechanism and control technique of highway in YiLi"from the YiLi highway bureau, aiming at large areas of tympanites pingoes on G313 and G218 asphalt highway in YiLi, the thesis makes a thorough study on development mechanism and control technique of highway tympanites from soil features of highway tympanites, tympanites mechanism, material and structure of resisting tympanites by investigation in situ, test and analysis.

本文基于国内外冻土研究现状和道路翻浆已有成果的分析，以新疆伊犁公路总段科技项目&新疆伊犁境内道路翻浆机理与治理技术&为依托，针对新疆伊犁境内G313、G218线沥青路面大面积的翻浆鼓丘，通过现场调研、实验和分析，从翻浆土体特性、道路翻浆机理、抗浆材料和抗浆结构研制出发，对道路翻浆机理与防治技术进行了深入研究，主要包括以下几方面内容：①道路翻浆土体特性研究通过实地考察和室内实验，翻浆土体粘土含量高，富含腐殖质，天然容重一般在17～20KN/m3左右，含水量18～30%。

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。

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。
