智能化系统在自燃温度测试中的设计和应用

为降低液体自燃温度测试过程中的操作危险,准确判定自燃现象发生及温度,减少繁琐的手工操作,参照ASTME659—78（2005）、GB/T21791-2008及GB／T21860-2008标准,设计了一套智能自燃温度测试系统。采用操作微机软件控制炉体升降温、自动进样泵进样、温度采集、自燃现象拍摄、尾气抽滤等过程,实现自燃温度测试从开始进样到吹扫尾气全流程的自动化;利用设计系统测试乙醇、丙酮等5种常见物质的自燃温度,测试结果与文献值的相对标准偏差不超过2．0％。结果表明所设计系统操作方便快捷、安全实用、结果准确。     

基于GIS的断层构造对滑坡灾害发育控制作用分析——以雅安市雨城区为例

断层是滑坡发育的影响因素之一。选择雅安市雨城区和区域内232处滑坡作为研究的基础资料,通过地理信息系统空间分析技术及作者提出的滑坡影响因子贡献率的方法,得到了研究区内断层100m和200m缓冲区对滑坡的贡献率,定量研究了断层对研究区域滑坡发育的关系。研究结果表明,研究区域断层对滑坡敏感性不大,100m断层缓冲区较200m断层缓冲区贡献率值较大,为下一步研究区域滑坡危险度区划奠定了基础,同时为区域防灾提供了科学依据。

Minimizing leakage from a smelter off-gas system by enhanced control

The off-gas handling system is a vital component of a smelter and it is essential that it operates in accordance with environmental regulations. A key feature of the off-gas management system is maintaining a slightly negative system pressure to prevent gas leakage, such as SO₂, out into the work and external environments. To enhance sustainable development, there is also growing interest in capturing and reusing the significant amount of heat and CO₂ contained within off-gas. The potential incorporation of heat and CO₂ recovery systems places importance on enhancing control to minimize the risk of both gas leakage and disturbance of the smelting process. With these requirements in mind, an easily implementable feedforward control enhancement to existing control schemes is proposed to help provide improved performance.     

Designing the sustainable product-service integration: a product-service blueprint approach

As a means for providing the sustainable production and consumption, the concept of product-service system (PSS) has received increasing attention. What is at the core in the PSS is the design, since it determines the distinctive characteristics and quality of PSS. Even though some tools have been suggested for PSS design, previous tools mainly focus on identifying the relationship between actors in a conceptual level. Despite the fact that it is significant and cannot be neglected, what is more important in a practical situation is to represent the detailed flow or relationship of PSS elements, with the consideration of products and services. In response, this paper proposes a ‘‘product-service blueprint’ which is a new and systematic way to elucidate the relationship between products and services, providing the implication of how PSS can provide the sustainable production and consumption. Employing the service blueprint as a starting point, new areas, lines, and symbols are introduced to represent the distinctive features of PSS. The proposed product-service blueprint represents the product use throughout the life cycle, service flow from the management to the customer, and the relationship between products and services. Taken together, the product-service blueprint will help both managers and researchers to promote the product-service integration under the concrete framework.
