NaY晶化母液制备硅铝胶的技术探讨

在导向剂法合成Y型分子筛的工艺下，晶化母液中SiO₂的含量为50～55g/l,Na₂O含量为20～25g/l，相当于模数为1.65～2.58的稀水玻璃，将晶化母液分离处理后，在晶化母液中加入一定量的硫酸铝溶液使硅沉淀,经过滤和水洗后即可制备出合格的硅铝胶，以便进行重新利用。     

破乳-酸化法处理直馏柴油精制废碱液

采用破乳 -酸化法对直馏柴油精制废碱液进行处理 ,筛选出最佳的破乳条件和酸化终点。实验结果表明 ,采用破乳剂或热力破乳 -酸化法预处理直馏柴油精制废碱液是一种有效的预处理方法。经该方法处理后的废碱液化学需氧量 (COD)下降率可达 93 4 %,除油率为 87%,副产物硫酸钠能得到最大限度地回收利用。同时 ,该方法设备简单 ,处理费用低廉 ,易于实现工业化。

Maternal Power Assertion in Discipline and Moral Discourse Contexts: Commonalities, Differences, and Implications for Children's Moral Conduct and Cognition.

Parental power assertion is traditionally studied in the behavioral domain--discipline triggered by the child's immediate misbehavior--but rarely in the cognitive domain--parent-child discussions of the child's past misbehavior. Maternal power assertion was observed in "do" and "don't" discipline contexts from 14 to 45 months and in the context of mother-child discourse about a recent misbehavior at 56 months. Mothers' use of power cohered across the "do," "don't," and discourse contexts, but its implications were domain specific. Power assertion in the "don't" discipline context predicted behavioral outcomes (more moral conduct at 56 and 73 months, less antisocial conduct at 73 months) but not cognitive outcomes (moral cognition at 56 and 73 months). Power assertion in the discourse context predicted less mature moral cognition but not moral or antisocial conduct. Mothers' high Neuroticism predicted more power assertion in all three contexts. Child effects were examined. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

试论鲁酒的风格特点

鲁酒整体上可分为浓香型粮食白酒、芝麻香型白酒和大众白酒。浓香型粮食白酒的风格特点有别于四川浓香型白酒，年产量近30万吨。四大酯的量比关系不同，川酒己乳比在1：0．65，鲁酒的己乳比在1：0．8；川酒突出己酸乙酯，窖香浓郁、香好，而鲁酒的风格则是窖香淡雅、醇和绵甜、顺柔爽净，味好。芝麻香型白酒则是鲁酒风格的典型代表，为全国白酒十大香型之一，典型代表酒是景芝白干。分两大流派：一是淡雅型芝麻香，特别是口感清正淡雅、爽净、芝麻香幽雅。以景芝白干、景阳神为代表；二是窖香型芝麻香。特点是窖香幽雅，绵甜醇和。芝麻香突出。以水浒特曲108为代表。大众白酒是鲁酒的优势产品。也是山东的传统酒。特点是口味纯正、香味协调、绵甜爽净，以国家优质酒坊子白酒为代表。     

Child negative emotionality and parenting from infancy to preschool: A meta-analytic review.

This meta-analytic review (k = 62 studies; N = 7,613 mother-child dyads) shows that effect sizes for the association between child negative emotionality and parenting were generally small and were moderated by sample and measurement characteristics. The association between more child negative emotionality and less supportive parenting was relatively strong in lower socioeconomic status families, reversed in higher socioeconomic status families, and limited to studies with relatively high percentages of participants from ethnic minorities and studies using parent report to assess negative emotionality. Higher levels of child negative emotionality were associated with more restrictive control in samples with less than 75% 1st-born children, as well as in infants and preschoolers, and in studies using parent report or composite measures to assess both negative emotionality and restrictive parenting. Finally, more child negative emotionality was associated with less inductive control. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
