  1. Abstract : through analysis of the components of coking on different parts of desullfur system of single tower and the waste water containing sulfur, we find the cause of coking in the stripping desulur system from single tower is the polymerization reaction of carbohydrate and the separattion of varied solid powders, organic compounds, and all corrosive productions of metal out of waste water in high temperature, therefore, the solving method is how to decrease the oil content, how to depolymerize form the carbohydrate and how to antisepticize by vapour of waste water

    文摘:對單塔脫硫系統中不同部位的垢物及現場催化含硫污水進行了分析測定，結果表明：塔內污垢成分及含量隨塔體部位的不同而不盡相同，單塔汽提脫硫系統中垢物的形成，主要是由於污水中所含各類粉塵、有機物、金屬腐蝕物等在高溫下因石油碳氫化合物的析出及其單體的聚合反應所致.如何降低污水中的含油成分、減少聚合反應的生成、防止污水蒸氣對塔體材料的腐蝕，是阻垢、除垢和防垢應解決的關鍵問題
  2. 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。
