車間空氣中三次甲基三硝基胺In this paper we studied the intercalation behavior of a new host matrix of x = l of zirconium proline - n - mtthyl phosphonate - phosphate ( a - zpmpp ), we successfully introduced butylamine heptylamine decanylamine ethanolamine diethylenetriamine ( 2e3a ) triethyleneteriamine ( 3e4a ) and tetrathyleneoctamine ( 4e5a ) guest molecules into a - zpmpp interlayer space. the intercalation complex were characterized by ir spectrum x - ray diffraction and tg - dsc thermal analysis, it has been found that a - zpmpp possess different intercalation behavior from a - zrp. because of the bulk of proline group, it affected the amount of guest molecule, mono - alkylamine form mono - molecule layer in the interlayer space, butylamine, decanylamine and ethanolamine form mono - layer and the carbon chain form 90 degree ordered assembly with the zirconium floor of a - zpmpp, every host molecule absorbed 0. 5 guest molecule
本文報道首次以x ? l的層狀（脯氨酸十一甲基磷酸一磷酸氫）鉛（ a zpmpp ）為主體底物，成功地將客體分子：正丁胺、正慶胺、正癸胺、乙醇胺、二乙烯三股、三乙烯四胺、四乙烯五股插入層狀化合物a zpmpp的層間，通過紅外光譜（ ir ） 、 x射線衍射（ xrd ） 、熱重分析（ tg dsc ）等手段對插層復合物進行結構表徵，結果表明： x ? l的層狀（脯氨酸件一甲基磷酸一磷酸氫）鉛具有不同於無機磷酸結的插層性能，由於層間脯氨酸基團的體積較大，影響客體分子進入的數量，胺分子在層板間取單層排列。Hexamethylenetetramine for industrial use

鹽酸溶液中六次甲基四胺對黃銅的緩蝕作用及吸附熱力學研究Rat cumulus - enclosed oocyte ( ceo ) and denuded oocyte ( do ) both spontaneously resume meiotic maturation in vitro, when cultured for 2h, the germinal vesical breakdown percentage of do reaches up to 88 %, and ceos get 53 %. oocytes begin to extrude first polar body 1 ( fb1 ) when cultured for 8h. mouse oocyte spontaneous maturation in vitro can be inhibited by 4mm hypoxanthine ( hx ) or 25um 3 - isobutyl - methylxanthine ( ibmx ). while, 4mm hx can not inhibit the spontaneous maturation of rat oocyte, and the lowest effective concentration of ibmx to inhibit rat oocyle spontaneous maturation in vitro is 50um. treated with the same concentration of ibmx, gvbd percentage of rat ceo is lower than that of do, the results indicat that cumulus cells delay rat oocyte spontaneous maturation and potentate the inhibition effect of ibmx, but it ' s not the case on mouse
Ceo和do培養8h時都開始排出pb1 ；在卵母細胞成熟抑制模型中， 4mm次黃嘌呤（ hx ）和25 m的異丁基甲基黃嘌呤（ ibmx ）是小鼠卵母細胞成熟的有效抑制劑，但4mm的hx抑制大鼠卵母細胞成熟效果不理想，用hx - m199和hx - mem培養24h ， gvbd率分別為61 ， 81 ，而ibmx有效抑制大鼠卵母細胞自發成熟的最小濃度為50 m ， ibmx可以降低大鼠ceo和do的gvbd率，但ceo中的卵母細胞gvbd率要顯著低於do的gvbd率， 100 m的jbmx處理24h后，大鼠ceo和do的gvbd率分別為24 ， 84 ，提示卵丘細胞的存在可以延遲大鼠卵母細胞的自發成熟，有助於抑制卵母細胞成熟，但在小鼠上ceo和do的自發成熟差異不明顯。The oxide and reduce potential and the dopant concentration. the experiments of degradation methyl blue a1so showed that the photocatalytic activity could be greatly improved with vzos - loaded tio2, maybe that loading v2o5 would accelerate the electron captured and charge transferring, change the samp1e surface hydrophilic and absorption
