eluviation n.淋濾(作用)。

eluvium

The intense eluviation and weathering of soil with groundwater and run - off result in the enhancing of capacity of transference of some elements , such as si , al , fe , mn . the chemical reactions of the colloid particles in the soil water make those crannies or holes filled by some epigenetic clay minerals and quartz . then a great deal of white reticulate clay comes into being in the quaternary laterite of the dongting basin 地下水和地表水強烈的淋溶作用使土壤中硅鋁鐵錳等元素的遷移能力增強,土壤膠體粒子之間的化學反應,使得這些孔隙空間在后期逐漸被次生黏土礦物和石英所充填,最終,在洞庭盆地第四系紅土地層中形成大量的蠕蟲狀和根狀白色網紋。

The distribution and change pattern of soil co2 concentration in soil profile data are analyzed as well as its effect factors . a model for soil caco3 eluviation - illuviation is developed based on mechanism of soil chemical thermodynamic principle and applying other modeling experience for reference 本文以磚窯溝流域為例研究和分析了土壤剖面co _ 2濃度的分布變化規律及其影響因子;對土壤碳酸鈣淋溶錠積進行了定性、定量研究。

Soil caco3 eluviation - illuviation is a relatively complicate process , soil co2 is one of the important effect factors , which influences soil caco3 through controlling soil ph value and caco3 solution capability 土壤碳酸鈣淋溶淀積是一個復雜的過程,土壤中的co _ 2通過控制土壤ph值和碳酸鈣的溶解性來影響土壤碳酸鈣的淀積,是重要的影響因子之一。

Results indicated that rain eluviation was one of the means by which p . multisectum released allelochemicals , the allelopathy of the leaching might play an important role in enhancing the competitive ability of the species 由此表明,雨水淋溶是多裂駱駝蓬向環境釋放化感物質的途徑之一,化感作用在增強其生態競爭力和擴大種群中起著重要的作用。

Soil caco3 eluviation and deposition process is the most important development and evolution process of soil , from parent material to mature soil in the loess plateau , arid and semiarid area 土壤碳酸鈣( caco _ 3 )的淋溶淀積過程是黃土高原以及干旱和半干旱地區土壤形成發育的主要過程之一,也是地球化學過程的主要內容。

This distribution pattern of soil carbon was related to such factors as the precipitation eluviation and the organism activities in soils 土壤碳的這種分布格局與大氣降水的淋溶、土壤生物活動等因素有關。

Research to the fertilizer efficiency of modified ammonium bicarbonate and its eluviation characteristics preliminary report 改性碳酸氫銨的肥效及淋溶特性研究初探
