尊严

人最宝贵的，不是地位和金钱，是生命。比生命宝贵的．是尊严。尊严．是看不见摸不着的，但却神圣。一个人可以失去生命，但不能失去尊严。在尊严的面前，施舍与怜悯都不再高尚，反而是种亵渎。一次偶然的机会，我见识了一个人的的尊严。那是一个夏日的午后，太阳火辣辣地炙烤着大地。人行道边的一棵榕树下面，一位衣衫褴褛的老人坐在那儿，嘴唇干裂，黝黑的脸上，豆大的汗珠顺着额头向下落，眼睛一动不动地盯着匆匆而过的行人。     

我们如何认识“师德”问题

教师被人们称为人类灵魂的工程师。教师要塑造学生的灵魂，首先要塑造自己的灵魂。教师教育学生既要言教，又要身教，而身教重于言教，所以教师必须加强职业道德修养，应具有优良的品德和高尚的情操。教师的职业道德，是教师为人的行为准则。只有具有良好师德的教师才能完成好教书育人的任务，才能在学生心中永驻其崇高的人师形象。现笔者对此观点谈几点认识。     

无密封无泄漏自控自吸水泵在酒钢CSP水处理系统中的应用

今日俄罗斯的铝冶炼工业

前苏联曾是历史悠久的铝冶炼大国,经历了70多年的沧桑,现已经发生了巨大的变化。我国的铝冶炼工业也是从苏联援建开始的。本文就前苏联铝冶炼工业的发展过程,苏联解体后的变化以及今日俄罗斯铝冶炼工业的新貌作一简介,以飨读者。1前苏联的铝冶炼工业前苏联最早的电解铝厂是1932年法国援建的沃尔霍夫(Volkhov)铝厂。1933年又建成扎波罗热(Zaporozhe)铝厂。那时,采用的是23kA的预焙阳极电解槽(简称预焙槽)技术。到30年代中期,开始采用60kA的侧插阳极棒自焙阳极电解槽(简称侧插槽)技术。由于军事工业的需要,前苏联的铝工业发展很快。二次世界…

从塑化剂到铝箔快餐盒

俗话说,民以食为天。人类为了生存,食物是绝对重要的。然而"吃什么、如何吃的健康"这个问题却一直在困挠着人类。台湾的塑化剂、内陆的毒餐盒都暴露出人们深深的担忧。对于商人的黑心和卫生部门监管的缺失,我们不得不呼吁,人们不能再对食品及食品包装掉以轻心了,无论是商人还是政府监管者都应当为人类的健康生存而负起责任。     

创新正未有穷时

创新，是发展的灵魂，是保持旺盛生命力和竞争力的奥秘所在。创新能力的高低，直接关系到一个企业竞争力的强弱。创新能力强的企业，其竞争力也强。反之亦然。企业创新能力的提升是企业竞争力提高的标志，培养和提升核心竞争能力是我们一切工作的出发点和归宿。这已成为大家的共识。     

中国历史上第一位女将军：妇好

妇好是商朝国王武丁的王妃。是位杰出的女政治家与军事家。由于妇好有很好的文化修养,商王武丁经常令她主持当时非常重要的祭祀与诵读祭文。她也被任命为卜官,成为武丁时期的一位女政治家。妇好也是位军事家。她多次带兵出征,立下赫赫战功。妇好死后,武丁十分悲痛。妇好有独葬的巨大墓穴,而且有拜祭的隆礼。这在商朝时期是非常少见的。

Design and optimisation of charging ingredients and structure in an ironmaking system (Part II)

In order to maximise the reduction of pig iron cost in an ironmaking process, and at the same time ensure the output and quality of the pig iron, a design and optimisation system for the charging ingredients and structure in an ironmaking system was established using metallurgical theory. The system includes six modules, namely, sinter metallurgical performance testing and analysis, sintering burdening design, sinter component and property prediction, blast furnace burdening design, blast furnace batching calculation and ironmaking system burden optimisation. Based on actual production, testing and material balance theory, the system integrated these modules on VB and MATLAB using a series of intelligent algorithms, such as the BP neural network, multiple objective linear programming, genetic algorithms and so on. As a result, the optimum burden composition and structure of the sinter and blast furnace that satisfied all the constraint conditions could be obtained. Standing as a pinnacle of the global ironmaking production, the system can design and optimise not only the sintering burden, but also the blast furnace burden. Compared with the traditional production testing and hand calculation in the ironmaking system, the project can greatly reduce the production risk and greatly increase the calculation accuracy. Industrial application shows that the system is especially beneficial to reduce the ironmaking cost and at the same time ensure the output and quality.

Lunar Astronomical Observatories: Design Studies

The best location in the inner solar system for the grand observatories of the 21st century may be the Moon. A multidisciplinary team including university students and faculty in engineering, astronomy, physics, and geology, and engineers from industry is investigating the Moon as a site for astronomical observatories and is doing conceptual and preliminary designs for these future observatories. Studies encompass lunar facilities for radio astronomy and astronomy at optical, ultraviolet, and infrared wavelengths of the electromagnetic spectrum. Although there are significant engineering challenges in design and construction on the Moon, the rewards for astronomy can be great, such as detection and study of Earth‐like planets orbiting nearby stars, and the task for engineers promises to stimulate advances in analysis and design, materials and structures, automation and robotics, foundations, and controls. Fabricating structures in the reduced‐gravity environment of the Moon will be easier than in the zero‐gravity environment of Earth orbit, as Apollo and space‐shuttle missions have revealed. Construction of observatories on the Moon can be adapted from techniques developed on the Earth, with the advantage that the Moon's weaker gravitational pull makes it possible to build larger devices than are practical on Earth.     

热轧不锈钢板酸洗工艺

为去除热轧不锈钢板表面的氧化层与贫铬层,钝化基体,改善表面质量,在热轧退火后需进行酸洗处理。介绍了热轧不锈钢板表面氧化层和贫铬层的组成与结构特征及其对酸洗过程的影响,并对热轧不锈钢板的酸洗体系设计和酸洗工艺开发进行了阐述。中国热轧不锈钢板普遍采用前处理(机械除鳞、中性盐电解等)→硫酸(电解)预酸洗→硝酸-氢氟酸终酸洗的酸洗工艺,旨在通过前处理和预酸洗去除大部分的氧化层,在终酸洗阶段去除残余氧化层及贫铬层,同时实现基体钝化。目前,热轧不锈钢板的酸洗工艺存在酸洗效果不稳定、贫铬层去除不完全、局部腐蚀较为严重等问题,且会产生不同程度的环境污染问题。应该根据不同钢种不同退火工艺条件下的表面氧化层与贫铬层的性质与分布特征,研究开发相应的酸洗体系和酸洗工艺。热轧不锈钢板的环保型酸洗新工艺具有广阔的发展前景。     

Impressions of psychotherapists' offices.

For counseling settings, research suggests that softness, personalization, and order might affect the experience and the perceived expertness, trustworthiness, and social attractiveness of the therapist. This article discusses exploratory studies on college students' perception of the counseling office environment and whether the likely client experience was associated with the softness/personalization and order of the office. As stimuli, the studies used 30 color photographs of psychotherapists' offices viewed from the client's perspective. After obtaining ratings of the characteristics of each office, we obtained ratings from different groups of students of the quality of care and comfort expected in each office (Study 1) and how qualified, bold, and friendly the therapist in the office would be (Study 2). Additional studies examined the likelihood of choosing a therapist based on the office, and the first thought or feeling that came to mind about the office, the therapist, and the patient experience. There were strong correlations in response between groups (by whether they had experienced therapy; their level in school; their gender; and their major, location, and school size). The quality of care, comfort, therapist boldness, qualifications of the therapist, and the likelihood that one would choose a therapist based on the office improved with increases in the office's softness/personalization and order. Friendliness improved with increases in softness/personalization. The office choices, open-ended responses, and reported reasons for the ratings confirmed the importance of softness (comfort) and order. Research should test longer term exposure and behavior.

Simultaneous and Sequential Photosonolysis of TCE and PCE

Aqueous solutions of trichloroethylene (TCE) and tetrachloroethylene (PCE) were treated in a flow-through reactor equipped with ultrasound and ultraviolet light sources. The reactor was operated as sonolysis (US), photolysis (UV), and simultaneous photosonolysis (UV/US) reactors; then as US, UV, and sequential UV/US reactors with the installation of a partition in the reactor. The reactor without the partition was simulated by using one continuously stirred-tank-reactor (1-CSTR) model, and the reactor with the partition was simulated by using the sequential CSTR model. Through model calibration, the decomposition rate constants and reactor efficiencies for the removal of TCE and PCE were evaluated. The results suggest that the combined effect of UV and US on the decomposition of TCE and PCE is synergistic in both the simultaneous and sequential UV/US modes, that the rate constants of sonolysis and photolysis are greater with the sequential combination than with the simultaneous combination, and that overall efficiency is higher for the reactor with the partition than for the one without it.     

浅谈加强建设工程招投标管理工作的重要性

对于建设工程的招标人来说,重要的是如何找到理想的、有能力承担建设工程任务的合格单位,用经济合理的价格,获得满意的服务和产品。根据建设工程的通常做法,建设工程的招标人均是严格按照法律法规的规定,通过招投标形式选择建设工程任务的实施单位,包括设计、监理、施工承包和供货等单位。可见利用招投标形式选择合格的实施单位,一方面从法律上保证了项目和项目法人的合法性,另一方面,也从技术上和经济上为项目的顺利实施提供了支持和保障。     

History of psychology.

If we accept philosophy as the search for knowledge about ourselves and the world around us by reasoning and we accept psychology as the use of science in the search for understanding the mind and behavior, we can get along without philosophy in our history courses very well. We can begin the history of psychology with the emergence of the life sciences in the early 1800s with passing kudos to the general emergence of science via Gallileo, Newton and Bacon. We can sanitize Fechner, Wundt, James and Dewey; ennoble Pavlov, Watson and Skinner; plunge into learning and psychobiology (while sanctifying logical positivism); and end amidst computers and cognition. And remain unscathed and untouched by human (and humane) reasoning and philosophy. Overall, from the perspective of a historian type, I am less and less certain about the present or the future without the sifting wisdom of history.
