這種鈣形態在濕潤地區許多土壤的亞表層也有累積。Caco3 not only affects soil physical and chemical characteristics but also causes co2 change in the air, because caco3 is main components among the total pool of inorganic carbon of soil. this paper systematically summarized and analyzed general development characteristics of soil profile caco3 in loess hill gully area including source, content, forming - condition, distribution and illuviation - depth of caco3, which will have the most important significance for the further studies on global soil and climate change
碳酸鈣在土壤剖面中淀積的深度和類型是黃土高原土壤發育的重要標志，鈣積層是黃土高原土壤發育環境的歷史信息庫，同時土壤碳酸鈣作為土壤無機碳庫重要組成，它通過溶蝕后再結晶與大氣co _ 2之間進行物質交流來影響全球氣候變化。Standard test method for measuring moisture vapor emission rate of concrete subfloor using anhydrous calcium chloride
用無水氯化鈣測量混凝土底層地板濕氣發散率的標準試驗方法When fillings is other materials ( unprocessed montmorillonite, powder coal ash, co - composite of powder coal ash and organo - montmorillonite, co - composite ofcarbonizing calcium and organo - montmorillonite ) in the binder and content of organo - montmorillonite in the binder is five percent decided by tensile - shear experiment, tensile - shear strength of binder is up to tiptop ; at the same time, this paper carries out abrasion experiment, and, by comparison, concludes abrasion property of coating is optimum when content of organo - montmorillonite in the binder coating is five percent, and observes abrasion sample under set
當膠粘劑中填料為其它物質（未處理蒙脫土、粉煤灰、粉煤灰和有機化蒙脫土共復合、碳化鈣和有機化蒙脫土共復合）時，通過拉伸剪切試驗確定膠粘劑中有機化蒙脫土含量為5時，膠粘劑的拉伸剪切強度最高；同時進行了沖蝕磨損試驗，通過比較得出，當膠粘劑塗層中有機化蒙脫土含量達到5時，塗層的耐沖蝕磨損性能最佳，並對沖蝕磨損試樣在掃描電子顯微鏡（ set ）上進行觀察。Road foundations. high - calcium lime for soils and roads. specifications

路基.道路和土層用高鈣建築石灰.生石灰水反應試驗The cultural deposits which are bracketed by the two flowstone layers should be of an age between 55 and 110 ka. the sixth flowstone layer gave date of 300 ka, which is much too old compared with the previous 14c age of - 15 ka on fossil materials
第4 、 5鈣板層間出土的石製品應是中國地區40 - 100ka間有人類活動的確證，表明「時間缺環」很可能只是測年技術應用不當造成的假象。And it is in spring that soil water content, soil organic matter and calcium and magnesium suffered more seriously damage from overgrazing
春季過度放牧對土壤表層的水分、有機質和鈣、鎂等元素造成的損失最為嚴重。However, the reserves of calcium bentonite is low and the surfactants are expensive, which bring many difficulties to industrialization. in this paper, an abundant and low cost raw material, calcium bentonite, and several new modifying agents such as compound quaternary ammonium salt with cheap caprolactam or anionic surfactant or silane coupling agent were used to synthesize new - type organobentonites, in the principal of efficient, cheap and simple
作者嘗試以資源十分豐富的鈣基膨潤土為原料，依據高效、廉價、使用簡單的原則，以傳統插層劑季銨鹽為基礎，分別用價格較低的己內酰胺、陰離子表面活性劑、硅烷偶聯劑部分取代季銨鹽作插層劑，來制備新型的有機膨潤土。分享友人
