Scientific Contribution Awards 1957.

"Distinguished Scientific Contribution Awards of the APA were presented to Edward C. Tolman (in absentia), Carl I. Hovland, and Curt P. Richter (in absentia) during special ceremonies at the 1957 APA Annual Meeting. Each recipient was presented, in person or in absentia, with a formal citation of his outstanding scientific contribution to psychology and an honorarium of $1,000." The citation for Edward Chase Tolman read in part: "For the creative and sustained pursuit of a theoretical integration of the multifaceted data of psychology… for forcing theorizing out of the mechanical and peripheral into the center of psychology without the loss of objectivity and discipline; for… his purposive-cognitive theory of learning." The citation for Carl Iver Hovland read in part: "For his original and provocative contributions to the scientific study of persuasive communications and the modification of beliefs and attitudes." The citation for Curt Paul Richter read in part: "For his pioneering investigations of physiological mechanisms affecting behavior." A brief biography and a complete bibliography of his scientific publications is included for each award recipient. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Gold Medal and Distinguished Scientific Writing Awards 1957.

The APF's second Gold Medal Award would have been given to Lewis Madison Terman. However, the APF's Board of Trustees "decided against a policy of awarding this medal posthumously and also against naming another award winner in his place this year." The Award for Distinguished Science Writing in the Field of Psychology consisting of a scroll and a check for $500 was awarded to Ernest Havemann. The citation in part read: "For his articles on psychology in Life magazine, January 7, 1957 to February 4, 1957… . Mr. Havemann's series was judged to be outstanding, not only for accuracy, lucidity, and interest, but for truly exceptional grasp of the diversity of modern psychological research and services." A brief biography of Mr. Havemann is presented and also part of his acceptance statement. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

高炉渣适宜镁铝比分段管控的分析与应用

 为了给现代高炉渣适宜镁铝比(w(MgO)/w(Al2O3))提供理论依据,定性定量地指导高炉操作,针对高炉渣的适宜镁铝比问题展开研究。首先,分析了高炉渣中MgO的必要性,即在现代化大高炉的冶炼条件下,随着高Al2O3外矿用量的增加,炉渣中含有适宜的MgO是必须的。炉渣合理镁铝比可根据Al2O3质量分数不同进行分段管控：当渣中w(Al2O3)小于14%时,MgO可根据生产要求添加;w(Al2O3)为15%～17%时,适宜的镁铝比(w(MgO)/w(Al2O3))应控制在0.40～0.50,但需注意炉温的影响;当渣中w(Al2O3)大于18%时,适宜的镁铝比应控制在0.45～0.55。在理论分析与试验研究的基础上,进行了工业化应用试验。试验期炉渣镁铝比由0.51降低至0.47,高炉焦比由363.39降低至357.82 kg/t,综合燃料比由495.23降低至试验期的494.18 kg/t,取得了良好的技术经济指标,证明了现代高炉渣镁铝比分段管控技术的正确性和可应用性。     

汞(Ⅱ)在罗丹明B-乙醇-硫酸铵体系中的析相萃取分离

研究了罗丹明B-乙醇-硫酸铵体系析相萃取Hg²⁺的行为及与一些金属离子分离的条件。结果表明,乙醇的水溶液在硫酸铵的作用下分成醇/水两相,在分相过程中,HgCl₄^2-与罗丹明B(RhB)生成的[HgCl₄^2-][RhB⁺]₂能被乙醇相萃取。当溶液中罗丹明B、乙醇和硫酸铵的浓度分别为0.21 mg/mL、30%(V/V)和0.30 g/mL时,HgCl₄^2-的萃取率达到96.8%以上,Co²⁺、Cr(Ⅲ)、Ag⁺、Mg²⁺、Ni ²⁺、Al³⁺、Ti(Ⅳ)、Pb²⁺、Fe³⁺、Sn(Ⅳ)和Ru³⁺基本不被萃取,实现了Hg²⁺与上述金属离子的分离。
