鹽基交換量
英文
base exchange capacity-
Determination of total exchangeable base in forest soil
森林土壤交換性鹽基總量的測定Our aim is to provide reference data for the mechanism of the effects of ree on crops and the safety evaluation of re used in agriculture. 1. in soil culture experiment, re applications with appropriate dose in dry condition increased the contents of soil available n, whose no - effect value were 505mg / kg at eighth week, whereas higher levels of re had negative effects, re applications with both appropriate and higher dose in inundated condition reduced the contents of soil nh / - n and hydrolysable n. re treatment concentrations showed significant positive correlation with the contents of soil exchangeable re. and significant negative correlation with the contents of soil available p and soil ph value. there was no significant effects of re on soil exchangeable cations, but applications of re increased the contents of soil water soluble cations, especially that of ca2 * and mg2 +
兩種培養條件下，稀土處理濃度與土壤交換態稀土含量成正比，與有效磷含量、土壤ph成反比，對土壤交換態鹽基離子含量無顯著影響，但通過置換作用增加了水溶態離子，尤其是ca ~ （ 2 + ） 、 mg ~ （ 2 + ）離子的含量；第二周稀土處理增加交換態zn含量，對交換態fe有降低作用，旱培條件下增加交換態mn含量，淹水條件下對其有降低作用；第八周稀土處理均提高交換態fe 、 mn 、 zn含量，其機制主要與稀土降低土壤ph有關。This climate make latosol usually as acidic, low levels cation exchanges capacity and low lever base cations, high levels of exchange al, with a high potential for leaching of plant nutrients
這種氣候條件使磚紅壤成為強酸性土壤，陽離子交換量和鹽基飽和度低，鋁飽和度高，化肥通過淋溶損失過程就更為突出。Based on solid - liquid interface ion exchange model, using in - situ data of ph, sediment concentration, trace metal and salinity in the changjiang estuary, solid - liquid phase transformation for metals cu, zn, cd, co, ni through salinity gradient was calculated, and the modeling results was compared with in - situ data sets reported in literature
華東師范大學博士學位論文摘要6 .在固一液界面離子交換模型的基礎上，以長江口現場調查得到的ph 、懸浮泥沙濃度、金屬濃度和鹽度作為模型的輸入量探討了cu 、 zn 、 cd 、 c 。In this paper, we make use of hexadesyltrimethyl, an approximate ammonium compounding ( 15 - ch2 - number 17 ), ocatadecylaminechloried as cation exchange agents. the montorillonite is treated with these agents, which results in marked increase in their organophilic properties. the orgnic - montmorillonite has been identified by x - ray diffraction, different thermal analysis and infrared adsorption spectra
在本文中，我們分別用十六烷基三甲基溴化銨、一種混銨鹽（ 15主鏈- ch2 -數量17 ）和十八烷基氯化銨作為陽離子交換劑，對蒙脫土進行了改性，使之由親水性變成親油性，繼而採用熔融插層方法制備了聚乙烯/蒙脫土復合材料。Based on the detailed investigation about the present conditions of polution in yichang and three gorges dc converter stations and its prediction, and concerning the esdd measurement of dc, ac equipment near the three gorges dc converter station, the operating experience and the atmospheric characters of the yichang city, the porper data of esdd of three gorges dc converter station is presented. and further more, presents the related structural parameters of outer insulation of out door dc, ac equiptment
針對宜昌市大氣污染和三峽換流站站址附近污穢狀況，結合三峽換流站附近交、直流設備鹽密測量和運行經驗以及宜昌氣候特徵，提出了三峽換流站適用的等值附鹽密度值，並在此基礎上提出了交、直流戶外設備外絕緣的有關結構參數。分享友人
