基于TRIZ进化理论的钢筋捆扎机产品需求分析
Requirement Analysis of Rebar Tying Machine on TRIZ Evolution Theory
 [PDF]


Journal of Electrical Engineering (JEE) , 2013, DOI: 10.12677/jee.2013.12011
Abstract: TRIZ技术进化理论应用于钢筋捆扎机的产品需求分析研究。首先对钢筋捆扎机的发展作了介绍,引出获取其新的需求信息的重要性;然后对产品需求概念和技术进化理论作了阐述;最后在此基础上对钢筋捆扎机进行了技术成熟度判定,并结合S进化曲线与进化法则的关系分析该产品进化方向,提取了该产品新的需求信息,为企业合理制定产品策略提供了科学依据。
 TRIZ technology evolution theory was applied to the product demand analysis about the rebar tying machine. Firstly, the introduction to the rebar tying machine was done, then the importance of capturing the new customer requirements was proposed. Secondly, the customer requirements concept and the TRIZ technology evolution theory were described. Finally, the maturity of the rebar tying machine was judged on that basis. Moreover, the evolution direction was analyzed with the relationship of S evolution curve and evolution laws. The new customer requirements were taken out. It provided a scientific basis for the enterprise to formulate the reasonable product strategy.
排放强度约束下我国碳金融市场的制度选择
The System Choice of Carbon Financial Market in China under Carbon Intensity Restriction
 [PDF]

Abstract:
面对气候变化的严峻形势,我国在推进碳减排工作中制定了相关政策和实践。但是由于现行环境管理推进模式存在很多弊端,使得我国的碳减排工作困难重重。因此,我国必须探寻一种新型的碳减排制度,提高我国碳减排领域的效率,降低减排成本。国际社会上碳排放强度提出后,显示出其对经济增长和治理环境问题的重要作用。联合国气候大会上,我国政府提出了基于碳强度指标的自愿减排的目标。因此,本文采用规范分析方法,提出建立碳强度约束下的碳金融市场是我国应对气候变化的必然制度选择。最终得出结论,我国需要从特殊国情出发,将碳强度与碳市场进行有机结合,建立一个基于碳排放强度指标减排的碳金融市场。并需要在限定排放目标的基础上,明确买卖主体,完成碳强度指标与碳总量指标的转化,最终实现分行业、分地区的碳交易。
Face to the serious situation of climate change, China has made the related policies and practices in promoting carbon reduction work. But, the current environmental management advance mode has many disadvantages; it made the carbon reduction work hard. Therefore, China must explore a new type of carbon reduction system to improve the efficiency in the field of carbon emissions, and also reduce the costs. Now, the international community has raised carbon intensity reduction mode, and it has showed its important role in economic growth and governance facing to the en-vironmental problems. In the UN climate conference, the Chinese government has presented the carbon intensity of voluntary emission reduction targets. Therefore, the establishment of carbon financial market under the restriction of carbon intensity is the necessary choice in China using the standard analysis method. We need to start with special national conditions in China, combine the carbon intensity to carbon market, and finally create a carbon market based on carbon emission intensity target. And we need to clear trading bodies, complete the conversion of total carbon to carbon intensity index on the basis of defining emission targets, and ultimately complete industry and region carbon trade.
基于数据挖掘的低品位油藏经营评价指标分析

Abstract:
本文针对高效经营未开发低品位油藏是我国石油行业即将面临的迫切任务情况,综合使用油藏经营思想、经济评价的分析方法和多种数据挖掘方法,提出了建立未开发低品位不同油藏经营效益评价的指标体系方法。通过大量实例统计研究,确定了低渗透和稠油未开发低品位油藏经营效益评价的指标体系。建立的未开发低品位不同类型油藏经营效益评价的指标体系可为油田企业评价该类油藏的经营效益,进而制定经营这些油藏的最佳方案奠定基础。
With the situation which operating efficiently untapped low-grade reservoirs is a urgent mission for our petroleum industry to execute, this paper presents the method to construct index system on benefit evaluation of untapped low-grade reservoir operation by using comprehensively the idea of reservoir operation, the analysis method of economic evaluation and multiple methods of data mining. Through a lot of case studies, the benefit evaluation index systems of untapped low- grade low permeable and heavy oil reservoirs are determined. These index systems may establish the foundation for oilfield enterprises to evaluate the operational benefit of untapped low-grade low permeable and heavy oil reservoirs and to formulate the optimal scheme of operating these reservoirs.
