用链带式活动滤槽法处理高炉水渣的设想

笔者在从事涟钢新3号高炉易地大修的设计中,针对以下情况:①新3号高炉场地狭小且无法利用原有水渣池;②涟钢高炉冲渣水时常不足,上下渣经常堆积;③冲渣沟内时常积有大块的干渣与小铁块,由于冲渣沟道很长且属高架式,清理困难且不安全,曾提出了一种新的高炉水渣处理方案——链带式活

DEVELOPMENT OF THE PERCEPTION OF FORM.

4 SCHEMES REPRESENTING THE FLOW OF INFORMATION FROM STIMULUS THROUGH SENSORY AND PERCEPTUAL SYSTEMS TO RESPONSE ARE PROPOSED IN THE CONTEXT OF AN EVALUATION OF THE PERCEPTUAL POTENTIALITIES AND ABILITIES OF THE NEWBORN HUMAN BEING. THE EVIDENCE SUGGESTS THAT THE NEWBORN IS PROVIDED AT LEAST SOME SENSORY CAPACITIES WITH WHICH TO SYNTHESIZE A PERCEPTUAL WORLD. SUGGESTIONS ARE OFFERED TO FACILITATE THE STUDY OF THE NEWBORN'S ABILITY TO PERCEIVE FORM. (2 P. REF.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

SOLUTION OF ANAGRAMS.

RESEARCH ON ANAGRAMS OVER 30 YR. BY SEVERAL METHODS DISCLOSES STRONG EFFECTS FROM 3 FACTORS: SETS ESTABLISHED BY INSTRUCTIONS OR A TRAINING SERIES, FREQUENCY OF EXPOSURE TO THE SOLUTION WORD, AND ORDER OF THE LETTERS OF THE ANAGRAM. EFFECTS OF LETTER COMBINATIONS ARE CONFUSING, BUT RECENT RESULTS CONVERGE TO EMPHASIZE THE FREQUENCY OF THE FIRST 2 OR 3 LETTERS OF THE SOLUTION WORD. MODEST PROGRESS HAS BEEN MADE IN THEORIZING ABOUT THE DEVELOPMENT OF THE SET, DESCRIBING THE PROBLEM-SOLVING PROCESSES, AND ANALYZING THE ABILITIES REQUIRED. THE RESULTS FOR ANAGRAM PROBLEMS HAVE IMPLICATIONS FOR SOME PERSISTENT QUESTIONS ABOUT PROBLEM-SOLVING RESEARCH IN GENERAL. (2 P. REF.)

ETIOLOGY OF ALCOHOLISM.

A COMPARISON OF M. C. JONES' (SEE 42:5) FINDINGS WITH THE OTHER LONGITUDINAL RESEARCH REPORTED IN ALCOHOL STUDIES (THE MCCORDS' WORK) POINTS UP SOME CHALLENGING AREAS OF AGREEMENT IN DESCRIBING THE PREADOLESCENT AND ADOLESCENT BEHAVIORAL CHARACTERISTICS OF THOSE WHO LATER BECOME PROBLEM DRINKERS. THE POTENTIAL PROBLEM DRINKER APPEARS TO BE A BOY WHO HAS LESS THAN ADEQUATE CONTROL OVER IMPULSIVITY, WHO OVERPLAYS THE ACTIVE MASCULINE ROLE, AND WHO TENDS TO USE DENIAL AS A MAJOR LINE OF EGO DEFENSE. IT IS STRIKING THAT 2 INDEPENDENT STUDIES, DIFFERENT IN RESEARCH POPULATION AND IN METHODOLOGY, AGREE IN DESCRIBING SOME ASPECTS OF PSYCHOLOGICAL PREDISPOSITION TO ALCOHOLISM.

PSYCHOTHERAPY OF PHOBIAS.

SOUGHT TO IDENTIFY THE COMMON ELEMENTS IN ALL FORMS OF PSYCHOTHERAPY WITH PHOBIC DISORDERS. THE BEHAVIOR PATTERNS CHARACTERISTIC OF PHOBICS ARE EXAGGERATED DEPENDENCY, WHICH THEY PERCEIVE AS INCOMPATIBLE WITH SELF-RELIANCE, AND EXAGGERATED AVOIDANCE OF DIFFICULT, FEAR-EVOKING SITUATIONS. THESE PATTERNS ARE LEARNED AS THE PERSON ADAPTS TO THE EXPECTATIONS OF OVERPROTECTIVE PARENTS. MOST THERAPISTS PARTIALLY RECIPROCATE THE PHOBIC'S DEMANDS FOR PROTECTION AND GUIDANCE, AND SUBSEQUENTLY USE THE INFLUENCE CONFERRED BY THIS RELATIONSHIP AS LEVERAGE TO URGE THE PATIENT TOWARD A DIRECT CONFRONTATION WITH THE PHOBIC STIMULI. BY BEING NEITHER OVERPROTECTIVE NOR HARSH, THE THERAPIST STANDS IN SHARP CONTRAST TO OTHERS IN THE PHOBIC'S LIFE, AND THUS PROVIDES A NEW INTERPERSONAL LEARNING EXPERIENCE THAT MOVES THE PATIENT TOWARD SELF-RELIANCE.

DIMENSIONS OF SIMULATION.

PRESENTS 3 INTERESTING CONNOTATIONS OF SIMULATION: (1) REPRESENTATION OR SUBSTITUTION OF 1 THING FOR ANOTHER; (2) PORTRAYAL OF THE ENVIRONMENT, WHICH SUGGESTS THE STUDY OF PERCEPTION; AND (3) DYNAMIC SYSTEMS AND THE FUNCTION OF COMPUTERS IN THEIR REPRESENTATION. EXPLORES THE USES OF SIMULATION FROM THE POINT OF VIEW OF RESEARCH AND DEVELOPMENT IN TRAINING. MAJOR SECTIONS ARE THE FIELD OF SIMULATION, OPEN-LOOP ENVIRONMENTAL SIMULATION, SIMULATION NOT INVOLVING PEOPLE, ANALYSES OF OCCUPATIONS, SIMULATION FOR TRAINING, REAL-SIZE SYSTEM SIMULATION, TECHNIQUES OF MINIATURIZATION, SIMULATION WITH EMPHASIS ON THE PEOPLE INVOLVED, AND SIMULATION FOR PROFICIENCY MEASUREMENT. 5 DIMENSIONS OF SIMULATION ARE IDENTIFIED.
