With the purpose of better understanding some weak links in this subject , we comprehensively and systematically compared the effects of some typical inhibitors and their different combined ways in inhibiting cd bioavailability in purple soil , further studied the laws and affecting factors of cd ' s transfer and transformation in soil - plant system , revealed the mechanisms inhibitors function , and explored the practicable inhibitor prescriptions and their usage . the results are expected to provide reliable techniques for controlling cd pollution of agricultural soils in chongqing and it is also significant to ameliorate soils polluted by other kinds of heavy metals . comprehensive methods including pot experiment , laboratory culture experiment , kinetic and thermodynamic adsorption - desorption experiment were adopted in this study , and the acidified purple soil was chosen to test , considering that cd is highly active in this soil 本研究針對重慶市農業土壤的污染狀況,選取鎘活性較高的酸化紫色土為供試土壤,采用盆栽試驗、培養試驗、化學熱力學與動力學吸附試驗相結合的方法,系統研究和比較多種調控劑及其不同組合方式對鎘生物活性的效應,并揭示鎘在土壤?植物系統中的遷移轉化規律及影響因素,進一步分析調控劑的作用機理,探尋具有實際應用價值的調控劑配方及合理使用的方法,這不僅可以為重慶市農業土壤鎘污染的防治提供可靠的技術保障,而且對于其它重金屬污染的治理也有一定的理論意義。

3 . the author designs ortho - experimentations of palygorskite acidification and organising modification by adopting propyl alcohol as thinner of wd - 51 , and acquires the best craft parameters and craft conditions for gaojiawang palygorskite acidification and acidified palygorskite organising modification , namely : the best craft parameters and craft conditions for gaojiawang palygorskite acidification is : parlygorskite : h2o = 1 : 3 , activation time 50 min , activation temperature 96 , hydrochloric acid concentration 1 . 0 n , parlygorskite granularity - 100mesh ; the best craft parameters and craft conditions for gaojiawang acidified palygorskite organising modification is : wd - 51 concentration 2 . 0 % ( wt % ) , modification temperature 120 , and modification time 60 mins , adopting iso - propyl alcohol as thinner of wd - 51 . 4 設計坡縷石粘土酸化正交實驗和有機化改性正交實驗,取得了高家洼坡縷石粘土酸活化處理和酸化坡縷石用wd - 51進行有機化改性處理的最佳工藝參數和工藝條件,即:高家洼坡縷石酸活化處理的最佳工藝參數和工藝條件為:固液比為1 : 3 (固體為高家洼坡縷石粘土,液體為去離子水) 、活化時間50min 、活化溫度為96 、鹽酸濃度為1 . 0n 、粒度為- 100目。

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,并溶解土壤和水體底泥中的重金屬進入水中,毒害魚類加速建筑物和文物古跡的腐蝕和風化過程可能危及人體健康。

Utilizing low denatured and defatted soybean flakers as material , a kind of functional food of soybean peptide nutrient solution which contains rich soybean peptide and little low - polysaccharide have been produced after the following production process : crushing , extracting , heat denaturing , enzyme digesting , acidifying , concocting , over - temperature sterling , canning , and so on 摘要以低變性脫脂豆粕為原料,經粉碎、浸出、熱變性、酶解、酸化、分離、調配、超高溫滅菌、灌裝等工藝生產出一種富含大豆肽、少量低聚糖的大豆肽營養液功能性食品。

Evaluating effects to parlygorskite organising modification by x - ray , tem , sem , ir , viscidity analysis etc . contrasting organising modification effects of parlygorskite original ore and acidified palygorskite , the result shows wd - 51 modification agent has better modification effect to acidified pargorskite than parlygorskite original ore 對比了用wd - 51對坡縷石原礦和酸化坡縷石進行有機化改性處理的改性效果,表明wd - 51對酸化坡縷石的改性效果要好。

Examples of natural - based additives are thickening agents from seaweed , antioxidants like tocopherols converted to vitamin e by the body and carotenoids converted to vitamin a by the body , and acidifying agents like tartaric acid from fruit 例子有從海草提煉出可使味道更濃厚的提味料,抗氧化劑像生育酚可被身體轉換成維他命

The factors mainly include soil acidifying , higher organic matter content in the soil , lead of precipitum in the air and the processing of the tea leaves in the factory 這些來源主要包括:茶園土壤酸化和較高的有機質含量,大氣沉降物中的鉛和茶葉的加工過程。
