气浮综合改进设施处理高浓度造纸废水

本文报道了气浮综合改进设施处理高浓度造纸废水的流程和改革，结果表明：改进后的气浮设施COD去除率由60％提高到75％，SS去除率由51％提高到71％，气浮出水河直接回用于造纸的主要过程，处理效果明显优于单纯的气浮处理。而且改进部分投资少，动力消耗少，是处理高浓度造纸废水的简便易行、值得推广的方法。     

The Impact of Criminal Conviction Disclosure on the Self-reported Offending Profile of Social Work Students

Correspondence to University of Edinburgh, School of Social and Political Studies, 31 Buccleuch Place, Edinburgh, EH8 9JT, UK. E-mail: richard.perry{at}ed.ac.uk. Summary Data gathered at a Scottish institute of higher education between1986 and 2000 indicate a significant reduction in the scaleof self-reported offending behaviour by social work students.The change coincided with the introduction by the Central Councilfor Education and Training in Social Work (CCETSW) in 1989 ofa requirement that applicants for training disclose prior toadmission any criminal convictions recorded against them. Thearticle suggests that more prolific offenders have been deterredfrom applying to DipSW programmes and the social work professionneeds to take steps to create a more positive climate for therecruitment of those offenders who represent no more of a threatto users than non-offenders.     

抗战时期西部的航空运输业建设

抗战爆发后,为打破日军封锁和开展大后方正常对外贸易,国民政府采取了一系列措施以重庆为中心发展西部航空运输业.西部航空运输业在发展中呈现出航线变动频繁、航空运输建设服从军事需要为主等特点.西部航空运输业经过三个阶段的发展,在一定程度上支持了抗战,并推动了整个中国民航运输业的发展.但由于航空人才缺乏、航空制造技术落后等原因,西部航空运输业的发展又难尽人意.     

大禹治水与龙蛇神话

将大禹治水与治水中的群龙问题联系起来加以考察解绎,可以看到禹治水神话中的群龙实是指洪水河川本身。洪水河川是龙诞生的生态起点和自然基础,是群龙之形的最原始的基形。群龙的动物性性状特征是以洪水河川中之蛇蟒蜥鳄为具象栽体。禹治水时的龙蛇尚不是夏部族的图腾。禹命名为“擒蛇”或“擒龙”,禹逐杀龙蛇状的共工、相繇,治水中“黄龙曳尾”等等原始事象均是以神话变形的方式涵藏或再现着群龙与自然洪水河川间的真切关联,是用神话语言认真而曲折地叙述着禹疏川导滞治平洪水的历史真实。     

Getting There: The Unfolding Potential of Psychoanalysis, A Personal View

Even though psychoanalysis has the potential to free the mind it can also (however unwittingly) be used to bind it. This paradoxical tendency is especially noticeable in some psychoanalytic trainings, when students can be under pressures to comply with accepted theory and practice and, in some cases, to toe the line in their training analysis and/or in their supervised cases. We therefore have to be increasingly mindful of the ways in which our training of psychoanalytic students can foster a false extension of psychoanalysis, by which the practitioner can become bound to a theory rather than be freed by it.
