关键词： 化工产品   市场营销   策略  

摘要： 当前我国经济发展十分迅速,使得化工技术水平得到了飞速提升,这也使得化工企业成为国内核心企业,与国家能源的发展有着直接的联系。但是当前的化工产品市场的营销情况十分不佳,其中主要就是因为营销策略的不合理从而造成营销策略存有缺陷。为此,需要根据市场对营销策略进行研究,总结出多种营销手段,结合自身企业化工产品的实际案例,深入研究市场营销策略,并对企业内部的营销问题进行全面分析,从而使得企业能够充分认知到营销策略方面的不足,并且找到问题的原因,以采用相应的对策进行解决。文章对化工产品市场营销策略进行了分析,并对化工产品营销策略当中的问题进行了探讨。

关键词： 人工合成着色剂   食品加工过程   固态食品   前处理方法   胭脂红   天然色素   化工产品   准确测定  

摘要： 当前食品加工过程中常使用到色素,色素又分为天然色素和人工合成着色剂两类。人工合成着色剂主要是以化工产品为原料,通过化学反应而制得,因性能好且价格低廉而被广泛添加到食品中,但长期过量摄入会对人体造成伤害。国家标准GB5009.35的前处理方法并不适用于固态食品,可操作性差、回收率低,本文以胭脂红为代表进行检测,对固态食品中人工合成着色剂的前处理进行研究。

关键词： Flash memory   Inter-cell interference   Hierarchical constrained codes  

摘要： Inter-cell interference (ICI) significantly affects the reliability of flash memory. Both horizontal and vertical ICI have been taken into account for the errors in flash memory. In this paper, we propose a two-dimensional hierarchical constrained code (2D-HCC) to mitigate both horizontal and vertical ICIs of flash memory. The proposed scheme is applied to both single-level cell (SLC) and multi-level cell (MLC) flash memory. Finally, the bit error rate (BER) of the proposed 2D-HCC with/without Bose-Chaudhuri-Hocquenghem (BCH) codes is simulated. The simulated results confirm the advantage of the proposed scheme.

ISBN: (纸本)9787514228427

摘要： 本书针对我国酚醛树脂行业过度依赖石化资源，植物单宁活性高、来源广泛、利用率低的现状，以制备高性能单宁基酚醛树脂为目标。首先重点介绍以低成本、产量大、富含单宁的落叶松树皮粉为原料，制备树皮粉、尿素共缩聚改性酚醛树脂，并作为胶黏剂应用于人造板工业中。其次以缩合类单宁（落叶松单宁、马占相思单宁）为原料，重点介绍缩合类单宁的不同解聚方法、解聚机理、低分子量降解产物分子结构等，缩合单宁解聚产物-尿素-苯酚-甲醛共聚机理和逐步共聚反应过程，并作为胶黏剂应用于人造板工业中。最后以橡碗树皮提取物水解类橡碗单宁为原料，通过原料分析，制备橡碗单宁-尿素-苯酚-甲醛树脂，并应用于木材胶黏剂。本书内容涵盖了目前国内在胶黏剂领域应用的主要单宁种类：落叶松单宁和橡碗单宁。本书的选题特点是紧扣国家可持续发展的基本国策，结合我国生物质资源丰富但利用率低的基本国情，为推动我国生物质材料的快速发展提供了知识储备。

关键词： Analytic Hierarchy Process   Uncertainty   Strength of knowledge   Chemical industry  

摘要： In this paper we review and discuss the use of Analytic Hierarchy Process as a basis for prioritising investments in safety measures in the chemical industry. We point out that such a framework is not, in general, adequate. First, uncertainty is not properly taken into consideration because the focus is on expected values. Second, little weight is given to the strength of additional knowledge. In this paper we recommend some adjustments to a traditional Analytic Hierarchy Process in order to better guide safety investments. The chemical industry is the starting point, but the discussions are to a large extent general.

关键词： COVID-19  

摘要： Executives representing more than two dozen companies gathered online on Apr 17 to discuss their organizations' responses to COVID-19--and offered reflections about the changes wrought by the pandemic--during a meeting of the AlChE Foundation's Corporate Council. In the meeting, the executives expressed admiration and gratitude for a workforce that has demonstrated resiliency in the face of unprecedented circumstances. They also described the associated challenges related to strategic planning, logistics, and workforce deployment beyond Spring 2020, across a landscape still clouded by ambiguity.

关键词： Intentional controlled islanding   Microgrid   Smart power system   Active distribution network   Blackout prevention   Cascade failures   Emergency control actions  

摘要： Blackouts or cascade failures are costly events which may threaten the integrity of electrical energy systems. The Intentional Controlled Islanding (ICI) is the last measure to reduce the undesirable technical, economic and social consequences of a blackout. In case of an emergency, the ICI of Distributed Generation (DG) units is a solution to preserve reliable power supply in a smart distribution grid. In this paper, three important aspects of ICI problem, namely the proper time of ICI (When), its optimal boundary (Where), and its execution method (How) are comprehensively reviewed. After reviewing the basic algorithms and procedures, to find the best (optimal) time, boundary and execution details, the different methods of the mentioned aspects are summarized and discussed. Finally, a discussion about current challenges and future trends of ICI in smart power systems (in distribution and transmission levels) are provided and moreover, a generalized framework for implementation of ICI in Active Distribution Networks (ADNs) and smart microgrids are presented.
