淋溶過程 的英文怎麼說
中文拼音 [lìnróngguòchéng]
淋溶過程
英文
leaching process-
It can also restrain the decomposition of organic substances in the soil and the bind of nitrogen, and wash away the nutritious elements, such as magnesium, calcium, and potassium. the acid rain deprives the soil. it acidifies the rivers and lakes, and dissolves the heavy metal in the soil into water, therefore poisons the fish
它可以直接使大片森林死亡,農作物枯萎;也會抑制土壤中有機物的分解和氮的固定,淋洗與土壤粒子結合的鈣、鎂、鉀等營養元素,使土壤貧瘠化;還可使湖泊、河流酸化,並溶解土壤和水體底泥中的重金屬進入水中,毒害魚類;加速建築物和文物古跡的腐蝕和風化過程;可能危及人體健康。( 3 ) the spatial analysis results showed that the variation of soil clay content was moderate at the direction of vertical section. the soil clay content was highest at the layer of 20 - 40cm, which showed that it is an eluvial accumulation horizon according to long - term cultivation, irrigation and rainfall
( 3 )土壤粘粒含量在垂直方向上呈中等變異,整個土體在20 - 40cm土層處的粘粒含量最高,說明土壤表層由於長期耕作、灌溉降雨,土壤粘粒含量有一個淋溶淀積過程。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乾旱和半乾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。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。In addition, the temporal pattern in the levels of soluble proteins in hemolymph, ovaries or eggs of this parasitic wasp was also defined during the processes of vg synthesis and uptake as well as vn degradation
此外,尚探討了卵黃蛋白合成、攝取和降解過程中,血淋巴、卵巢或卵內可溶性蛋白含量的時間動態變化。The main results are following : ( 1 ) the variation of clay / silt ratio can indicate the secondary clay action of dust depositions ; the variations of magnetic susceptibility and total fe content are inferred to be records of the changeable intensity of bio - pedogenesis ; the variations of sr content and rb / sr ratio can indicate bio - pedogenesis, dissolving and leaching action ; the content of total organic carbon ( toc ) can reflect variation of climate and vegetation during soil formation, it indicates the intensity of weathering and bio - pedogenesis ; the content variation of caco3 can show the intensity of dissolving - leaching action and secondary deposit, which was noted as pseudomycilia in pores and fissures in the sediment, so it can indicate the intensity bio - pedogenesis quite well. these proxy indexes also reflect obvious regional difference of pedogenic environment and the intensity bio - pedogenesis ; namely, secondary clay action, dissolving - leaching action and bio - pedogenesis are all much stronger in south than that in north
實驗結果表明:粘粒粉沙比值能很好地指示粉塵堆積物的次生粘化作用;磁化率和全鐵很好地指示生物風化成壤作用; sr和rb sr比值能很好的指示生物風化成壤作用和淋溶作用;總有機碳( toc )含量的高低,在一定程度上反應了土壤發育過程中氣候和植被狀況的變化,指示著成壤過程中腐殖質化的程度; caco3含量的變化,可以反映了黃土古土壤形成時的風化成壤作用的強弱程度,指示成壤過程中的淋溶作用和次生碳酸鹽化作用;並且各指標所指示的成壤環境和成壤強度存在明顯的區域差異,即渭河流域土壤的生物風化成壤作用、次生粘化作用和淋溶作用均表現出南部強于北部。Severe fires can often cause changes in successional rates and soil hydrologic functions, degradation of soil physical properties, alter c : n ratios, and result in subsequent nutrient loss through accelerated erosion, leaching or denitrification, and alterations in microbial populations and associated process can occur
高強度火燒往往能引起演替頻率的改變,土壤物理性質退化,水文功能發生改變,改變c n比,加劇侵蝕、淋溶和反硝化作用,導致養分流火,微生物數量及其相關過程發生變化。The space produced by the crystallization is the second. the pores and the fractures, which have been remade by the chemical dissolution, are more favourable for the oil and the gas to store up
變質巖儲集空間以構造和物理風化成因的裂縫為主,結晶成因的儲集空間次之,這些孔、縫經過化學淋溶作用不同程度的改造,更有利於油氣的儲集。Therefore, changes in compositions and levels of several biochemical substances, including cuticular hydrocarbon, pteridine, protein and uric acid during growth and development of some common species of necrophagous flies were measured and analyzed, and then the potential of using change patterns in those biochemical substances as age indicators in necrophagous flies was discussed
為此,本文特對不同種屍食性蠅類生長發育過程中表皮碳氫化合物、蝶啶、血淋巴可溶性蛋白和尿酸等的變化規律進行了較系統的測定分析,進而分析了這些變化規律用於幼蟲、蛹或成蟲日齡推斷的可行性及推斷方法。Optimization of project subcontract jit procurement with a nash equilibrium model and its application in mining project
