風成粘土 的英文怎麼說
中文拼音 [fēngchéngniántǔ]
風成粘土
英文
aeolian clay-
Clays are produced by mechanical and chemical weathering and primarily colloidal in size.
粘土是由機械和化學的風化作用形成，主要是膠粒大小。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。Mz, a, sk, kg and sc / d ( ratio of the sum of silt and clay to sand ) of fluvio - lacustrine, palaeosols and aeolian sands constitute an interlocking, multi - fluctuation process curve with peak and valle y values : the < & value of mz, o and sk values often increase accordingly from aeolian sands to its overlying fluvio - lacustrine facies or / and palaesols, the kg value heightens, too, and the sc / d value also basically consists with its change steps
河湖相和古土壤與風成砂的mz 、 、 sk 、 kg以及sc d （粉砂粘土之和與砂的比值）構成一峰谷交替、犬牙交錯的鋸齒狀多波動過程線：常常是由風成砂至上覆河湖相或和古土壤， mz的值、 、 sk值相應增大， kg相應增高， sc d值亦與之變化步驟基本一致。Grain - size accumulation percentage of the aeolian sands in the past 150 ka in milanggouwan section is mainly characterized by the aeolian palaeo - mobile dune sands, which are composed of majority fine sands and minority very fine sands. there is n ' t almost any silt and clay. those of the fluvial facies, especially the lacustrine facies and palaeosols, are mainly composed of very fine sands and also contain some quantities of silt and clay
米浪溝灣剖面150kabp以來風成砂的粒度累積百分含量以古流動砂丘砂物質為主，其中以細砂含量最高，極細砂為次，幾乎不含粉砂與粘土；河流相、特別是湖沼相與古土壤以極細砂含量占優勢，且具一定含量的粉砂和粘土。The second stage is stage of the matter transfers the activated matter, that is to say, minerals build up their surface area after passing though physical weathering, maifan stone form a lot of clay mineral, oxide, oxhydroxide and collide mineral after passing though chemical weathering. it makes nutrition elements transform from crystal state to adsorption state and it expands the activation of mineral, in the latter stage, it makes maifan stone have many special physicochemical adjusting character, for example, ph and foi bi - directional absorptive and ion exchange character, so these characters expand maifan stone ' s uses
第二階段為物質轉變的活性階段，即通過物理風化增大表面積、通過化學風化形成大量粘土礦物、氧化物和氫氧化物及膠體礦物，使營養元素由結晶態轉變為吸附態，從而大大增加了其活性。在後一過程中麥飯石還形成了許多特殊的物理化學性質，如ph值和f _ （ o2 ）的雙向調節性，吸附性和離子交換性等，從而擴大了其用途。Double disk stir cooler can accelerate evaporating moisture for getting low temperature with strong stirring of scraper in short time through water feeding, blast and convulsions ; meanwhile, it has definite function of rebirth and mixing for old sand, which makes it become the best device for old sand treatment of clay sand system
雙盤攪拌冷卻機，能在短時間內在刮板的強烈攪拌下，通過加水鼓風抽風，促使水分蒸發以達到降溫的目的，同時對舊砂有一定的再生混勻作用，使其成為對粘土砂系統舊砂進行冷卻的最佳裝置之一。Based on analyzing and determining basic characteristics of every raw material, the dispensation tests had been performed about clay - cement paste, fly ash - cement paste, fly ash - clay - cement paste and wind - blown soil - clay - cement paste, and their performance figures were tested systematically and obtained perfectly so that a reasonable dispensation formula was get to be used in filling project
在分析測試各種原材料基本性能的基礎上，按正交試驗設計方法，完成了粘土?水泥漿、粉煤灰?水泥漿、粉煤灰?粘土?水泥漿和風積土?粘土?水泥漿的配比試驗，並對其各項性能指標進行了系統的測試和分析，得到了可供工程應用的合理配方。As we know, when meeting these soils, many breakdown and danger will occur, such as the blockings, which has attracted attention of many construction personal on site. however, at present, there exist many unknown fields in blocking. firstly, the definition of blocking is not interpretative
但是，如果地層是粘粒含量較少的卵石層、砂土地層、風化巖地層，進入壓力艙的土體就很難形成這種「塑性流動狀態」 ，從而嚴重阻礙施工進程甚至造成施工事故，閉塞就是常見的一種施工障礙，已經引相關方面的重視。分享友人
