清晨冷丁醒来,几点了?立马儿起身,跑向书房。匆忙中看了一眼方厅的钟,坏了,6点10分了,我的菜啊!打开电脑,上网。果不其然,我种的萝卜6点成熟,现在,过了十分钟,已经被网友偷了个够。自从弟弟去年十一来我家,教会了我在网上 相似文献

就像餐巾纸替代了手帕一样,书信也逐渐被手机和电话挤出了历史舞台。如今,亲朋好友之间很少用写信的方式来沟通和交流了。有事了,思念了,只要轻轻地按几个数字,便可听到对方的声音,快捷而便利。但是现代文明在给我们带来方便的同时,也让我在不知不觉中失去了许多人间最美 相似文献

本文综述了自由基聚合链转移反应的机理及发展历程,着重概述了基于加成一断裂链转移机理的链转移剂在自由基聚合中的应用。主要的加成-断裂链转移剂类型包括乙烯基醚类,烯丙基硫代化合物、砜、卤化物、磷酸盐类,烯丙基过氧化物类以及硫代羰基类化合物。加成一断裂型链转移剂能够在自由基聚合中作为分子量调节剂,控制聚合物的分子量及分布,并能广泛用于常用单体中。该类链转移剂为制备末端功能化聚合物、嵌段聚合物提供了一种有效的途径,在印刷和包装用油墨、胶黏剂等高分子材料领域,有一定的应用前景。 相似文献

This paper outlines two innovative projects carried out within the same organisation, but with markedly differing results. One has been satisfactorily completed while the other, although having run for much longer, is still experiencing technical problems. The two projects, British Rail's Advanced Passenger Train, and High Speed Train, are examined in relation to the concept of uncertainty. It is suggested that many of the points upon which the projects are differentiated can be attributed to the degree of uncertainty to which they were subject. It is concluded that one means of handling the uncertainty associated with development programmes is to adopt a flexible approach. It is noted, however, that flexibility may not be simply a question of personnel or organisational disposition, but can be influenced by the characteristics of particular projects. 相似文献

经济系统的资源位凹集模型及其政策含义 总被引:6,自引:1,他引:6
本文首先论述了“系统经济,整合为王”的基本思想;在此基础上提出了经济系统的资源位凹集模型把经济系统的实际资源位结构构造成凹集是整合在所有权意义上不属于自己的资源的必要条件,这为如何发展系统经济指明了方向;根据这个模型,推广了国际贸易理论的Heckscher-Ohlin定理,提出了如何应对经济全球化和如何在国际分工中获得最大的国家利益的对策性建议和必须进行的观念转变;最后,在对科斯企业理论进行认真分析的基础上,提出了企业凹集模型,进一步指出在系统经济条件下,整合资源的能力是企业家的核心能力的新理念。 相似文献

The formal ties that bind collaborating organisations are often assumed to be reinforced by the relationships of individual employees, and these by trust. So, too, are the personal networks by which employees acquire much of the information required for the organisation's innovation. It is easy to assume that personal networks should support collaborative arrangements. It is also tempting for managers to ensure that they do by bringing them under organisational control. This paper investigates collaboration in Esprit, the European Commission's programme for research in information technology. It finds personal networks, and considers the implications for innovation of attempts to render these networks compatible with collaboration. 相似文献

近年来中国玩具设计发展迅速,涌现出一大批优秀的玩具设计师和设计创意,各种吸引孩子目光、锻炼孩子能力的玩具层出不穷。然而,部分身体上存在缺陷的儿童,其选择玩具的范围就显得非常狭小。为这个群体设计和制作玩具,往往被企业所忽视。本文讲述如何设计出适合视觉障碍儿童的玩具,帮助视觉障碍的儿童获得对外界世界的认识,帮助他们接触和了解社会,使视觉障碍儿童在玩玩具的过程中获得乐趣,培养出健全的健康的人格,提高其对生活的信心。为身体存在缺陷的儿童设计制造玩具,不仅仅是扩大企业产品的范围,更是一份爱心和责任。 相似文献

This paper is concerned with one central question: the choice between theories, and the role played by data in that choice. It deals with the uses economists may make of data and the importance of understanding the institutional basis that gives rise to the data - an area in which labour economists have traditionally been particularly strong - and with the relevance of assumptions. It deals with the ultimate need to choose between competing theories (despite the role of conventionalism) on the basis of data rather than retreating into a comfortable 'methodological pluralism'. It considers the role of test replication, with reference to the practice in natural science (and its role there in checking scientific fraud) and concludes that, despite extensive technical problems of testing, economists have to accept a data check if the rhetoric of mathematical technicality is not to overwhelm the need to explain. Parallels are drawn with experience in physics (and the implications of the development of Chaos and Catastrophe for a naively predictionist view are noted), medicine and history (of which, it is argued, modern economists are far too neglectful). 相似文献
