Degradation of chlorophenol by in-situ electrochemically generated oxidant

INTRODUCTION With the development of industry, more and more pollutants are discharged into environment, among them, phenolic wastes are typical contami-nants considered to be hazardous and top priority toxic pollutants listed by the USEPA. They are toxic even at low concentration. Due to their biorefractory, bioaccumulation and carcinogenic potential, the treatment of these contaminants is very important in environmental protection. Various technologies and processes have been tried …     

大学生心态状况调查及其积极心态培养对策研究

文章利用一般自我效能感量表和简易应对方式量表，对某校大学生作抽样调查，结果显示：不同性别和专业的大学生在自我效能感和应对方式上无显著差异；大学生自我效能感的来源存在偏差，主导性的应对方式也有错位。这表明当代大学生的心态并非都是积极的。因此，高校思想政治工作者要高度关注和研究大学生的心态问题。要培养大学生基于能力的自我效能感，要形成以行动为主导的应对方式，要建立起积极心态培训机制。     

Between two Advisors: Interconnecting Academic and Workplace Settings in an Emerging Field

This article examines a new training design for continuing professional development that aims to support the learning of the novel knowledge and skills needed in emerging professional fields by interconnecting academic and workplace settings. The training design is based on using two advisors, one from working life and the other from an academic context. The article examined whether participants’ personal orientation to adaptive expertise predicts the success of a guidance process. The interconnection of workplace and academic contexts was expected to occur through guidance practices. In addition, the features underlying the most successful guidance relationships were analysed. Data were collected by conducting repeated semi-structured interviews with 18 course participants, eight academic advisors and eight workplace advisors in the context of a 1-year energy efficiency training programme. The results indicated that a trainee’s personal orientation towards adaptive expertise is a significant component in successful guidance processes. An interconnection of workplace and academic knowledge and practices was hardly found in the guidance provided by each participant’s academic and workplace advisors. The feature underlying the most successful guidance relationships are related at the personal, dyad and context levels. An excellent match between the expert profiles of the learner and the advisor appears to be especially critical for successful guidance and powerful knowledge exchange in emerging fields. However, finding matching advisors is often challenging. Many problems are presumably solved if these ‘right persons’ can be found and if the trainees are themselves oriented to utilise the novel resources provided to them by the advisors.     

Novice teachers’ learning and knowledge building during the induction programme

This paper explores the Estonian novice teachers’ learning and knowledge building (LKB) practices in the extended professional community during the induction programme using well-known knowledge conversion model. The assumption in this study is that a teachers’ participation in the extended professional community facilitates their professional development. The survey was conducted with 101 novices after their induction programme. The patterns of novices’ LKB practices in the professional learning community during the induction programme were explored. The analysis showed to what extent extended professional community may be formed during the induction year. LKB practice patterns among the novices were identified. We discovered that many novices felt that there was insufficient support from other teachers and from university experts. It appears that it is challenging to develop a coherent induction programme as the extended professional community of educators, where different partners collaborate and share professional knowledge is challenging.

消除误区 求解木牛流马——兼评木牛流马研制现状

木牛流马制作于汉中勉县的黄沙。木牛流马由诸葛亮创意、构思,蒲元参与研制,可能还有其人参与了制作。民间有传说诸葛亮从其妻处获得木牛流马的设计。《南史》和宋人对木牛流马的记载对后世的影响极大,造成的误解也大。木牛流马运行的道路不是蜀道。用木牛运粮走的是"出祁山"的道路,用流马运粮走的是褒斜道,都不是蜀中的金牛道、剑阁道。木牛运行道路是诸葛亮北伐"出祁山"的路线以西北方向迂回道路为主,道路相对平坦。流马运粮所走的是褒斜栈道,比较宽阔、平缓,有一定起伏。人们对小说《三国演义》中描述的木牛流马存在误解。今人对木牛流马研制的主要成果有:范文澜先生认为木牛是独轮车,流马是四轮车;刘先洲先生提出木牛流马是鹿车(独轮车)的改进;陈从周、陆敬严先生认为木牛流马是独特的独轮车;谭良啸、方北辰先生先后提出木牛流马是两种规格不同的四轮车;王湔先生复制的四足迈步型木牛流马;赵彬、向国富先生的杠杆单摆型木牛。从物理学的原理评今人研制的木牛流马:车轮滚动型——古代运载物资的最佳形式;杠杆驱动型——构造合理而相距真实甚远;四足迈步型——不靠谱的机械步行器。研究、复制必须以《作木牛流马法》为依据。诸葛亮的木牛、流马一是制作不会太花费精力、财力、人力;二是一定能负重,载重量应符合要求;三是关于行进速度,必须把握,这是研制木牛流马的一个突破口之一;四是既然名曰"木牛流马",应该以木构件为主,结构不会太复杂,构件加工难度不会太高。这也是研究和复制木牛流马的方向及条件。     

网络翻译的利与弊

在因特网时代,网络资源可以提高翻译效率。通过对翻译软件、论坛（BBS）和新闻组的研究,网络翻译可帮助查单词和词组,并减少拼写和语法错误,进而提高翻译的质量。但因特网并不是万能的,也具有自身的缺陷,翻译工作者在使用因特网辅助翻译时应该趋利避害。
