中文拼音 [fúhuàshuǐyuán]
氟化水源
英文
fluorinated waters-
Burning furnace is one key equipment of ahf unit, it supplys heat energy for the turning furnace
燃燒爐是無水氟化氫裝置的關鍵設備,它為轉爐提供熱源。According to the water supply source used the mining area in bai yun, based on the mechanism of coagulation and flocculation, the feasibility of removing fluoride from water with the method of coagulation and filtration is studied through experiment. and several key parameters which affect defluorination are also analyzed. by using polyaluminum chloride ( pac ) as coagulant, the optimum ranges of the operational parameters are obtained
本文根據白雲鄂博礦區飲用水的供水水源,以混凝機理為基礎,通過靜態和動態實驗,對用混凝過濾法除氟的可行性進行了研究,並對影響除氟因素的幾個主要參數進行實驗分析,得出了用堿式氯化鋁作為混凝劑進行實際運行時,參數最佳取值范圍。We have prepared a series of neodymium binary / ternary complexes, such as nd ( acac ) 3 ' 2h2o, nd ( tfa ) 3 ' 2h2o, nd ( hfa ) 3 ' 2h2o, nd ( dbm ) 3 ' h2o, nd ( acac ) 3phen, nd ( tfa ) 3phen, nd ( hfa ) 3phen, nd ( dbm ) 3phen, nd ( tta ) 3 ( tppo ) 2, nd ( hfa ) 3 ( tppo ) 2, nd ( acac ) 4hpy, nd ( tta ) 4hpy and ndq3. the effects of organic ligands, synergistic coordination agents and different substitution groups for - diketones on effective line width and photoluminescence intensity of neodymium complexes were investigated. the photoluminescence spectra indicate that synergistic coordination agents can shield neodymium ion and impede water molecules penetrating into inner coordination shell to satisfy large coordination number of nd3 + during hydrous synthesis process, so the luminescence intensity of neodymium ternary complexes is stronger than that of neodymium binary complexes
發光光譜研究表明,由於協同試劑的參與,屏蔽了水分子參與配位,降低了羥基( oh )對釹離子激發態能級~ 4f _ ( 3 2 )的猝滅,三元配合物的熒光強度均比二元配合物強,其中配合物nd ( tta ) _ 3 ( tppo ) _ 2在1340nm處的熒光強度最強,適合作為摻雜的光學活性物質,來制備有源光波導材料;在有水工藝條件下,單純地氟化配體未必能提高釹配合物的近紅外發光性能。In february 1992, nasa scientists announced that levels of chlorine monoxide resulting from the breakdown of cfc ' s were at record levels above the northern hemisphere near the arctic and that these conditions could cause an ozone hole to develop over much of europe, canada, russia, and northern portions of the united states by the year 2000
1992年2月,美國國家航空與航天局科學家宣布,北極附近的北半球源於氯氟化碳分解的一氧化氯處在前所未有的水平上,同時宣布這種情況可能引起歐洲、加拿大、俄羅斯和美國北部等許多地區臭氧空洞的發展。分享友人
