Shuitu Baochi Xuebao, 2005 通过对高吸水性树脂在不同肥料溶液中吸水倍率和肥料养分吸持量的测定,研究了不同吸水倍率的聚丙烯酰胺型、聚丙烯酸盐型、淀粉接枝型高吸水性树脂与氮、磷、钾肥料的相互影响。结果表明:化学肥料能显著降低高吸水性树脂的吸水倍率,并随肥料浓度的增加,高吸水性树脂吸水倍率显著降低。但不同肥料品种对高吸水性树脂吸水倍率的影响程度不同:供试肥料对高吸水性树脂的影响程度依过磷酸钙、磷酸一铵、硫酸钾、氯化铵、硫酸铵、氯化钾、尿素顺序递减。高吸水性树脂在水中溶胀时,在吸收大量水的同时,也吸持溶解在水中的肥料分子或离子 ...

Components Analysis and Classification of Beer and White Spirit Based on NMR Approach [PDF]
, 2016 食品是人类生活中一类重要的必需品，各种食品具有不同的特性和成分，直接关系人体的健康。近年来，我国食品安全问题受到社会公众群体的广泛关注。核磁共振(NMR)技术相比于其他传统的检测方法，具有对样品的制备要求低、预处理简单，无损检测和高灵敏度等特点，在食品科学研究中得到广泛应用。 酒精类饮料属液态食品，啤酒更是继水、茶之后世界第三大饮用品，白酒则是中国特有酒种。目前基于NMR技术对啤酒的研究多停留在定性分析，化学成分的描述一般只针对某类化合物，对总体化学成分的全面研究较少。而基于NMR的白酒研究集中在国内 ...

Research on the application of soy protein based adhesives in wood adhesives [PDF]
, 2016 近来石化资源日益枯竭，随着低碳节能减排、绿色健康环保等理念的不断深入人心，人们越来越多地对石油工业带来的问题进行反思并开始关注与研究可再生资源。木材工业中，对大豆蛋白制备木材胶黏剂的研究最为广泛，这主要是由于大豆资源丰富、产量高，大豆蛋白质大分子中含有氨基、羟基、巯基等活性反应基团，通过改性可使大豆蛋白胶黏剂的性能有较显著提升。 本文是首先以大豆分离蛋白为原料，酸碱、尿素及十二烷基硫酸钠和十二烷基磺酸钠为基础改性剂，在不同的pH值、反应温度、反应时间的条件下，制备得到基础改性胶黏剂 ...
