高炉上部锌在焦炭上的富集及赋存形式的研究

摘要：锌作为有害元素,在高炉内循环富集给生产带来了一系列不利影响,但锌在高炉中的赋存形式未有定论,为此,设计了一种新的实验方法,模拟研究了高炉上部锌在焦炭上的富集及赋存形式。实验结果表明,温度在493～905℃范围内,焦炭表面和内部均附集着较多的细小的颗粒状氧化锌;温度在493℃以下,焦炭表面附集着珠状金属锌和氧化锌,但内部锌较少;焦炭表面在温度低于493℃时富集的锌在493～905℃温度范围内进行转变,焦炭表面附集着白色致密结壳和众多小颗粒组成的球形氧化锌,但焦炭上仍有金属锌存在,同时焦炭内部存在的锌也较多。     

Least squares evaluations for form and profile errors of ellipse using coordinate data

To improve the measurement and evaluation of form error of an elliptic section, an evaluation method based on least squares fitting is investigated to analyze the form and profile errors of an ellipse using coordinate data. Two error indicators for defining ellipticity are discussed, namely the form error and the profile error, and the difference between both is considered as the main parameter for evaluating machining quality of surface and profile. Because the form error and the profile error rely on different evaluation benchmarks, the major axis and the foci rather than the centre of an ellipse are used as the evaluation benchmarks and can accurately evaluate a tolerance range with the separated form error and profile error of workpiece. Additionally, an evaluation program based on the LS model is developed to extract the form error and the profile error of the elliptic section, which is well suited for separating the two errors by a standard program. Finally, the evaluation method about the form and profile errors of the ellipse is applied to the measurement of skirt line of the piston, and results indicate the effectiveness of the evaluation. This approach provides the new evaluation indicators for the measurement of form and profile errors of ellipse, which is found to have better accuracy and can thus be used to solve the difficult of the measurement and evaluation of the piston in industrial production.

A structural service innovation approach for designing smart product service systems: Case study of smart beauty service

Smart Product-service systems (PSS) are the emerging type of PSS that offer market value and dynamic intelligence combining products and services as solutions to consumers based on digital technology. To design a smart PSS with an effective way, a structural design approach is required. Nevertheless, only a few existing researchers discussed this topic. Aiming to bridge this gap, an integrated way is proposed for smart PSS design. This study refines a generic approach for structural service innovation approach which integrates the advantage of PSS engineering and service engineering for designing smart product service systems. The structural design approach is based on the Theory of Inventive Problem Solving (TRIZ) incorporating with service blueprint named PRR method. Three design phases are demonstrated as verification of the PRR method by an elaborated case study of the smart beauty service. Based on PRR, three key design phases are integrated, i.e., (1) problem definition, (2) resolution generation, and (3) resolution design. Empirical results and implications are collected and discussed to obtain valuable insights for value creation.     

振冲系泊桩基础成桩试验研究

目前海上风电以单桩或群桩基础为主,基础依靠深插桩体满足风机结构竖向抗拔承载力要求,随着大功率海上风电机组的投产与安装,如何提高桩基础抗拔承载能力成为制约海上风电大规模发展的瓶颈。本文以改进的振冲器为施工器械,结合预应力锚杆关键技术,综合振冲加固与高压旋喷桩的施工工艺形成了振冲系泊桩成套施工技术,提出了振冲系泊桩新型桩基础;开展了现场成桩试验和现场载荷试验,结果显示:运用该成套技术形成的振冲系泊桩桩身完整性良好且具有较强的抗拔性能;进行了有限元模拟仿真,分析了振冲系泊桩承载机理和破坏模式,通过仿真计算知3.5 m桩长的振冲系泊桩在一般黏土地基中的单桩极限抗拔承载力可达450 kN,是相同桩长的圆柱桩的7.5倍。     

符号消费下的家具形态辨识与释义

符号是意义的承载物,是人类情感外观化的表现。人们把消费行为作为一种实现自我价值和建立社会关系的手段,进而表达自身独特的主体性。当人们根据自己的价值观来选择与之相适应的家具形态时,家具形态就会成为一种符号,与消费者产生情感共鸣。因此,符号学方法论与家具消费变成了一种积极的关系方式。从家具形态的内涵入手,具体分析家具形态的多种符号释义和消费者对家具形态的识别认知过程,以及对应产生的心理变化。通过研究符号语义的传播方法,解释家具形态内涵与消费情感的互动关系,找出家具形态感知的基本模式和设计要素,探索家具设计与消费情感含义的本质联系,用符号学的观点揭示消费者对家具形态的辨识与释义。     

On effect of tool rotation on performance of rotary tool micro-ultrasonic machining

The present research paper is based on a comparative study of stationary tool micro-ultrasonic machining (STMUSM) and rotary tool micro-ultrasonic machining (RTMUSM). Microchannels were developed on glass work material by using both processes. The effect of tool rotation on the performance of micro-USM was investigated. The performance of both processes was compared on the basis of material removal rate (MRR) and depth of channel (DOC) as response characteristics. The power rating, work feed rate, concentration of abrasive slurry, and abrasive mesh size were chosen as variable input process parameters in this investigation. The form accuracy of the fabricated microchannels was analyzed with the help of imaging technique. Also, a qualitative analysis of tool wear was carried out with the help of microscopic images. The experimental results revealed that the tool rotation significantly improved the performance of micro-USM. The RTMUSM resulted in 155% and 147% higher MRR and DOC as compared to STMUSM. The tool wear was also found to be lesser in RTMUSM as compared to STMUSM and as a result of that form accuracy of machined microchannels improved.
