堿衡算 的英文怎麼說
中文拼音 [jiǎnhéngsuàn]
堿衡算
英文
soda balance-
Beginning with the analyse of present situation and cause of formation of saline - alkali land, the irrigated area overall water salt trends are analysed, and the irrigated area saline - alkali land and the groundwater level and distribution law of groundwater degree of mineralization are expounded, the trendence of irrigated area saline - alkali land is put forward. then water salt balance model is estanbished according to the relationship of irrigating and drainage. regarding the irrigated area as a balance area, by analysis of mineralization degree of water pumping from the yellow river and drained off water from irrigated area, the change of the draining off water ion is forcasted in water reducing condition
課題研究主要從鹽堿地現狀與成因及灌區總體水鹽動態分析兩方面入手，闡述了灌區鹽堿地、地下水位、地下水礦化度的分佈規律，分析了灌區鹽堿地的成因及變化趨勢；根據灌區灌溉、排水條件與以上各種因素的關系，建立了灌區水鹽均衡模型；把灌區作為一個均衡區，通過對黃河來水礦化度、灌區排水礦化度的分析，預測了在灌溉引水、排水減少時排水離子量的變化；運用灌區水鹽動態模型原理，對灌區現狀（ 1998 、 2000年）與規劃水平年總體水鹽平衡進行了計算；總結分析了灌區水鹽動態變化趨勢，計算並提出了排水控制標準。Abstract : the equilibrium constant of carbonization reaction of lime white was calculated using three thermodynamics methods. the results indicate that the carbonization reaction of lim white was the neutralization reaction between acid and alkali first, and it was the transform reaction of precipitation second. the essential cognition of the carbonization reaction of lime white was deepend. it was of guiding significance for industrial production of light ( precipitation ) calcium carbonate
文摘:用3種熱力學方法計算了石灰乳碳化反應的平衡常數，結果表明，石灰乳的碳化反應首先是酸堿的中和反應，其次才是沉澱的轉化反應，從而加深了對石灰乳碳化反應本質的認識，對輕質（沉澱）碳酸鈣的工業生產有指導意義
