长期以来,我国洗选加工工业发展缓慢,特别是无烟煤的洗选加工更为落后。全国仅有五座无烟煤洗煤厂,且大都是洗选无烟块煤。随着国民经济的发展,各用户对无烟煤质量的要求越来越高,不仅化肥、机械、军工等部门要求高质量的无烟块煤,而且冶金、碳素等行业也迫切要求供应低灰低硫的无烟末煤。因此,洗选无烟末煤已引起人们普遍注意。但洗后无烟煤的经济效果如  相似文献

Abstract
The purpose of this bibliographic study is to identify trends of interest in the field of the management of technology in the last 20 years. The data used are based mainly on a classification of the topics covered by papers printed in this journal since its first publication in 1970.
On the whole, interest in most of the topics has remained steady, notably in economics of R&D, communication, innovation and creativity. The only notable decrease in interest has been in project evaluation and selection. Relative to their importance, the authors remark that in some areas in which interest has remained steady, such as creativity and innovation, not enough is being done. Areas in which interest has increased include organizational issues, the interface between R&D and production and the impact of information technology. Interest in technology strategy increased over the early part of the review period but has recently declined.
The authors conclude by listing topics which strongly deserve attention by workers in the field. They cite integration of R&D into corporate strategy, organizing for technological flexibility, technology assessment and transfer, speeding up the R&D process, measuring the impact of new information technology, intrapreneurship and defining the role of basic R&D in technology development.  相似文献

于2013年春、夏、秋、冬四季采集石家庄市6个采样点PM10和PM2.5样品,分析其中的多环芳烃,研究了石家庄市PM10和PM2.5中PAHs在不同季节的污染水平、组成特征和主要来源。结果表明,石家庄市PM10和PM2.5中有15种PAHs检出,全年PM10中PAHs的质量浓度为7.5~510.5ng/m3,PM2.5中PAHs的质量浓度为3.6~460.6ng/m3;PAHs浓度季节变化明显,冬季浓度明显高于其他季节。春、夏、秋、冬四季PM10和PM2.5中的PAHs主要分布在细粒子中。4环和5环化合物是PAHs的主要成分,占比为66%~79%。与其他季节相比,冬季4环PAHs的含量高,5环和6环PAHs的比例相对低。运用比值法综合分析,石家庄市PM10和PM2.5中PAHs在冬季主要受到燃煤污染源的贡献,在春、夏、秋季,受燃煤污染和机动车污染综合作用。  相似文献

EPC工程总承包中的风险控制   总被引:3,自引:1,他引:2  
文章通过对工程总承包中各环节的风险原因和规避措施分析后认为,工程总承包中对风险的有效控制包括两个方面:一是配置合理的管理人员,二是完善各阶段管理制度和运行机制,明确工程风险责任是降低风险损失的有效途径。例如,对合同与设计进行会审和动态管理;采购、施工部门在设计阶段的关键节点上要有所介入,参与方案和施工图会审;在采购阶段,要进行阳光采购;在施工阶段,完善专家负责制。在各阶段都应建立责任追究制,以便在出现事故时能够明确责任。  相似文献

《国际石油经济》编辑部与士研传媒共同举办的“2012亚太石油贸易国际会议”,聚焦行业热点问题,在开放的平台上与来自各国的专家共同研判未来亚太地区特别是东北亚地区的石油贸易变化趋势,探讨如何利用金融工具规避石油贸易风险,展望石油仓储船运业的发展前景.亚洲与中国在世界石油贸易的新秩序下还没有完成角色转换,缺少在国际石油贸易中的话语权.因此在石油金融领域,中国正在推动石油贸易的人民币结算,推进中国原油期货上市.此次会议还分享了韩国提出的建立东北亚石油枢纽的构想.会议的成果对促进本地区石油贸易、石油合作和石油安全具有重要参考价值.  相似文献

目前碳捕捉与封存(CCS)技术作为一种新的温室气体减排手段受到西方发达国家热捧,然而目前CCS还远未达到商业化推广阶段,其大规模实施还存在一定的不确定性。中国作为煤炭生产和消费大国,CO2减排形势相当严峻,对CCS进行深入研究就显得十分重要和迫切。由于我国在该领域的研究刚刚起步,为促进我国CCS的研究工作,对国内外的研究现状进行了综述,从研究领域、研究角度和研究方法总结了发展趋势,并指出了目前研究中还需要进一步加强的领域。  相似文献

This article summarizes the activities performed by the Network for Capacity Development in Nutrition in Central and Eastern Europe and Balkan countries (NCDNCEE) in the past decade. The article gives a retrospective of the achievements and challenges in building capacity in nutrition research.Recognizing the lack of capacity and incoherent nutritional situation in CEE/BC, the United Nations University (UNU), Food & Nutrition Programme and the UN Standing Committee on Nutrition (SCN) encouraged the formation of NCDNCEE in 2005, which became CAPNUTRA in 2012.The network’s aim was to initiate and support tailor-made activities for capacity development in food & nutrition in research and training in CEE/BC. To identify the challenges and needs of nutrition research in the region, the network performed inventories on existence of food composition databases, food systems elements, dietary surveys, micronutrient recommendations, application of dietary assessment methods and grey literature. Further on, the network focused on the development of food composition databases and concomitant data management software, the Diet Assess & Plan platform for food consumption collection, dietary intake assessment and nutrition planning. These and other elements form the Balkan Food Platform, which underpins harmonized nutrition research in CEE/BC. Among key actions promoted by the platform are EFSA-supported dietary surveys conducted in four Balkan countries, on children and adults, in which food consumption data are collected and analysed in a harmonized way. Cooperation with FAO and active participation in international research projects enhanced the exchange of information and knowledge and brought international recognition to the CAPNUTRA network.  相似文献

论全球价值链中我国企业创新与市场势力构建的良性互动   总被引:34,自引:0,他引:34  
当代国际新分工是以进出口诸方在产品生产的多个环节上混合使用多种要素从而组成全球价值链为特征的,由于我国企业普遍缺乏市场势力致使发达国家跨国公司通常在国际竞争中处于主导地位,而我方则面临低端锁定、利益扭曲、引进依赖等不利格局。我国企业若能构建、强化市场势力,则可提升自主创新的动力与能力,扭转不利局面。本文从理论上探索了企业创新与市场势力良性互动的机理,进而在“环”、“链”、“群”三个层次上就如何构建“良性互动”提出了思路与对策。  相似文献

Irrigation,agricultural performance and poverty reduction in China   总被引:1,自引:0,他引:1  
The overall goal of our paper is to understand the impact that irrigation in China has had on grain production and incomes, in general, and income and poverty alleviation in poor areas, in particular. The paper seeks to meet three objectives. First, we describe the relationship among irrigation status, yields and household crop revenue. Second, we seek to understand the magnitude and nature of the effect that irrigation has on yields and crop revenue. Finally, we seek to understand the impact that irrigation has on incomes in poor areas. Our analysis shows that irrigation contributes to increases in yields for almost all crops and in income for farmers in all areas. The importance of crop income in poor areas and the strong relationship between crop revenue and irrigation provides evidence of the importance of irrigation in past and future poverty alleviation in China. We also show that in the majority of the villages that invested in new irrigation, returns are positive even after accounting for increases in capital and production costs.  相似文献
