电力题材摄影经常拍摄厂房和设备,除了特殊的表现手法以外,一般情况下要做到“横平竖直”,不能发生“倾斜”。如果条件所限(比如说手头摄影器材不适或者时间等方面的原因)不能满足要求,那也不要紧,可以在电脑后期处理中加以修正。 相似文献

为了提高空调连杆涂油的效率和质量,设计了一款空调连杆自动涂油机器人。提出了龙门式三轴涂油结构与模具盒辅助定位的总体设计方案,制定了涂油工艺路线,对涂油机器人的机械结构进行了结构设计和运动分析,选用西门子S7-200 SMART作为控制系统核心进行设计,确定了硬件接线图和控制流程,通过伺服电机驱动、传感器模块、人机交互界面等实现对涂油机器人的自动控制。采用UG软件对涂油机器人的各部分结构进行三维建模,并进行虚拟装配,检验设计的合理性。结果表明,所设计的涂油机器人可以实现空调连杆的自动涂油,其生产效率比手工方式提高了约40%,并无漏涂和涂刷不均的问题出现。该涂油机器人的设计改变了传统手工涂油方式,其结构可靠、容易操作、效率较高,可为其他不规则工件的自动涂油提供一种新的解决方案。 相似文献

人工智能技术的发展,既提供了以自动化技术为主要特征的新动能,也提供了对人类脑力劳动进行分解、模拟和延伸的全新技术手段。工业机器人作为人工智能技术在生产领域的核心载体,既可以利用自动化技术成为工业生产的发动机,也可以通过生产工具创新和生产知识创新实现工具机的价值。本文基于Becker and Murphy(1992)分工模型,刻画了工业机器人引发生产方式变革的演化路径:工业机器人首先以发动机的形式完成可自动化范围内的任务,进而以工具机的形式辅助劳动力实现非自动化范围内生产环节的分割重组,反向推动自动化范围内子任务的分工深化,最终实现整个任务区间生产方式的转变。经验研究表明:当工业机器人应用量达到一定规模时,增加工业机器人投入能够促进生产分割程度提升,行业研发投入的增加则会加速生产分割的进程。工业机器人应用对劳动生产率的影响过程与转变生产方式的演化路径高度吻合。本文的研究为政府引导工业企业“聚焦人工智能核心技术攻关,通过工业机器人应用加快推进生产分割”提供了理论与经验证据。 相似文献

This article analyzes the engagement of Japanese, Korean and Chinese participants in the development of Internet standards at IETF on the basis of four quantitative metrics: attendance, patenting, authorship and leadership. The results are strikingly divergent. Japanese involvement in Internet standardization began early and Japan was, for many years, second only to the U.S. in terms of IETF participation. Though Japanese participation has declined since the early 2000s, Japan remains a major contributor to IETF standardization. Korean involvement in IETF has always been significant, but below the levels of Japan and major European countries. Korean participation in IETF has also declined over the past decade, and has been dominated by one firm, Samsung. Though meaningful Chinese involvement in IETF did not begin until the mid-2000s, it has rapidly expanded in recent years. Today, China is a major player in numerous areas of Internet standardization in terms of three metrics (participation, patenting and leadership), and is rapidly gaining in terms of document authorship as well. Most of China׳s recent IETF involvement can be attributed to Huawei, though other Chinese firms have recently begun to increase their participation in the organization. Thus, contrary to some views that China׳s engagement with standardization is primarily one of indigenous innovation and “catching up”, China׳s experience with IETF demonstrates deliberate and effective engagement with a major Western standards-development organization on its own terms. 相似文献

This paper explores the idea that a sense of school subject image is a necessary feature of curriculum management and a potent force for change. The discussion centres on the view that all school subjects have an image and that if those intimately involved with the subject do not control the image then someone else does! In such circumstances the image is the product of past encounters and old euphemisms and is unlikely to hold the changed realities.The UK developments in Design and Technology education (the term Design and Technology is used to denote the school subject defined under this heading by the UK National Curriculum, 1995) have created something of an image problem which has interesting international parallels. Some of these problems are due to clearly discernible internal tensions and an ambiguous relationship with other subject areas.Through greater attention to subject image internal controversies might be acknowledged and resolved, relationships with other subject areas can be more meaningfully understood and practitioners can be helped to make sense of curriculum change. 相似文献

This special section aims to investigate the interaction of global and local forces in shaping agrifood governance. It starts from the recognition that a multitude of actors and norms shape today’s agrifood system. The resulting opaqueness of the systems makes it extremely difficult to understand and explain processes and outcomes of agrifood governance. Given the sustainability challenges facing the agrifood system, improvements in our understanding of what the interaction of global and local actors and norms means on the ground are urgently needed, however. The section, therefore, analyses agrifood governance in India across a selected group of cases. It does so by employing a systematic framework emphasizing the material and ideational dimensions of power and their interaction. The section has chosen India as the setting in which to analyze this interaction due to the crucial role the food demand and supply of this rising power plays in today’s agrifood system. This article provides the special sections’ analytical framework, which uses the interplay of material and ideational dimensions of power as a focal lens. In addition, the article applies this framework to an empirical study of the political conflict around GMO foods in India, specifically the case of ‘Golden Rice’. 相似文献
