中文拼音 [ruòsuānzhí]
弱酸值
英文
weak acid number-
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。Abstract : the extraction of purple pigment from brassica campestris and its stability were studied. the pigment is stable under acidic condition, worth to develop in food industry
文摘:以紫菜薹為原料，用30乙醇溶液浸提制得紫菜薹色素，並對其理化性質進行了研究。結果表示該色素在弱酸性條件下，具有較好的穩定性，在食品工業中有一定的開發利用價值。Natural mild acidic foaming agent that is similar to the skin ' s ph level ; able to create rich leather cleansing foams and makes the skin feeling fresh without drying
天然的弱酸性起泡劑，與皮膚之酸鹼值貼近，可產生豐富細致的泡沫，洗后肌膚健康清爽，沒有繃緊作用。Peg and superfluous aa reaction by complete concatenation method, the esterify production " esterify water " and acid number were mensurated, it shows that the esterify reaction would be processed under 100 esterify temperature and with amine accelerantthe tide of esterify reaction was substantiated by ir. in the ir spectrum, the characteristic peak of hydroxy of peg and carboxyl of aa were weakened. and the ester link of peg was reinforce. the " esterify water " was increased gradually and the acid number of esterify production was debased gradually along with the extent of esterify time and the augmentation of molecular weight of peg
通過聚乙二醇與過量的丙烯酸採用全連續法進行反應，測定酯化產物「酯化水」和酸值等宏觀手段反映出在胺類促進劑、 100的酯化溫度等條件下的酯化進程，而利用紅外光譜（ ir ）分析所反映的聚乙二醇的羥基和丙烯酸的羧基特徵峰減弱，而pea的酯基特徵峰加強等特徵進一步證實了宏觀手段所表現出來的酯化趨勢：隨著酯化時間的延長和聚乙二醇分子量的增大，產生的「酯化水」逐漸增加，酯化產物的酸值逐漸降低；從酯化時間看，當反應時間達到300min時，酯化物的酸值達到最小，而從ir分析來看，酯化物pea4的羥基峰在300min時減弱到最小， pea23在120min時羥基峰的表現出酯化基本完全。The information of the carbon and oxygen isotopes in the ground - water ' s in carbonate plays an indicated role in the seperation the ground water system. and in the end of the paper, some prelimilary suggestion have been naturally put forward for the stop of the leakage in the dam foundation
