铝材轧制添加剂的相容性研究 总被引:4,自引:1,他引:3
研究了CSA铝材轧制复合添加剂与美国ESSO公司的Wylor10、Wylor12添加剂以及各种基础油的相容性能。结果证实几种添加剂混合后无沉淀产生、无分层现象出现;CSA添加剂与众多基础油也有良好的相容性,配制轧制油后不分层,不产生沉淀。实验结果为国内外轧制油添加剂的混合使用提供了科学依据。 相似文献

锗蒸馏残液的环保处理工艺研究 总被引:1,自引:0,他引:1
为有效降低锗氯化蒸馏残液的产生量、回收残液中的盐酸,本文配合残液的末端处理技术,通过回收盐酸实验以及残液处理实验,研究了在锗氯化蒸馏工艺中用氯气替代硫酸的可行性。结果表明,用氯气替代硫酸是可行的,锗的蒸馏率提高了0.41%,残液中H+浓度由13.25mol·L^-1降至6.5mol·L^-1左右,从而更容易处理。回收的盐酸中H+浓度为6.52mol·L^-1,回收率达到70.3%,残液的总量可由220m3降至66m3。按照现在的生产规模(1×10t·a^-1金属锗),采用此工艺节省硫酸280t,消耗的生石灰减少390t,减少中和渣570t。针对锗蒸馏残液中主要含盐酸的工况,提出了残液资源化的处理工艺流程,即首先采用蒸馏工艺对残液中的盐酸进行回收,再用石灰中和残液,使中和上清液完全用于制备石灰乳。 相似文献

节俭在中国传统社会倍受推崇,是由于它有利于养德养廉和富国裕民,而它的时代意义在于体现了科学发展观和合理消费观,是发展与消费的协调统一。就我国目前市场上大部分商品包装而言,正是因为缺乏节俭的意识,给社会造成极大危害,我们倡导的简约包装和绿色包装是蕴涵“俭德”的商品包装形式,不但维护了消费者的利益,更节约了资源、保护了环境,这是商品包装发展的理性走向。 相似文献

The authors examined in 3 experiments the comprehension of counterfactuals, such as "If it had rained, the plants would have bloomed," and semifactuals, such as "Even if it had rained, the plants would have bloomed," compared with indicative conditionals, "If it rained, the plants bloomed." The first experiment showed that people read the negative conjunction, "not p and not q" faster when it was primed by a counterfactual than when it was primed by an indicative conditional. They read the affirmative conjunction, "p and q" equally quickly when it was primed by either conditional. The 2nd experiment showed that people read the negated-antecedent conjunction, "not p and q" faster when it was primed by a semifactual conditional. The 3rd experiment corroborated these results in a direct comparison of counterfactuals and semifactuals. The authors discuss the implications of the results for the mental representations of different conditionals. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Competence is an issue of vital importance for all practicing psychologists, and each spends his or her career seeking to develop it, achieve it, maintain it, and enhance it. But just what is competence, how is it best achieved, what are the factors that may adversely impact it, and what are each psychologist's ethical obligations with regard to clinical competence? These and other relevant questions are addressed for psychologists individually, for those who train them, and for those in the profession who establish professional standards. The article and 3 invited expert commentaries address these issues and make practical recommendations for action that will assist psychologists, trainers, and the profession to better achieve the ideal of competence so that they may best be able to meet the needs of those they serve.

Freud wrote his Psychology for Neurologists (which Strachey called A Scientific Project) in 1895. He wrote it in a feverish state within a month, yet quickly buried it. His intensity in writing it and in suppressing it has not been explained, but intriguing hints about it from Freud's correspondence with Fliess are discussed here. The work remains, however, foreshadowing many of Freud's important psychological concepts. Further, although it is often dismissed because of archaic neurological ideas, many neurological guesses that Freud presented in Psychology for Neurologists are in keeping with neuroscience of today. Aspects of mechanisms of the brain, understanding dreams, developmental perspectives and clinical ramifications all relate to what Freud said in this draft for a monograph.
