摘要： Sensitivity Analysis (SA) investigates how the variation in the output of a numerical model can be attributed to variations of its input factors. SA is increasingly being used in environmental modelling for a variety of purposes, including uncertainty assessment, model calibration and diagnostic evaluation, dominant control analysis and robust decision-making. In this paper we review the SA literature with the goal of providing: (i) a comprehensive view of SA approaches also in relation to other methodologies for model identification and application; (ii) a systematic classification of the most commonly used SA methods; (iii) practical guidelines for the application of SA. The paper aims at delivering an introduction to SA for non-specialist readers, as well as practical advice with best practice examples from the literature; and at stimulating the discussion within the community of SA developers and users regarding the setting of good practices and on defining priorities for future research.

关键词： 高频电子线路   知识点   教学实践  

摘要： "高频电子线路"课程内容繁杂、相关性小,学生难以建立课程概念,难以总结教学内容。为了帮助学生总结所学知识,加深对课程的理解,本文对"高频电子线路"的知识点总结方式进行了分析和研究,设计了基于关键词和知识点网络的总结方法,该总结方法有助于提高"高频电子线路"的教学效果。

关键词： 热力学   等效温度   有限时间热力分析法   热力系统优化  

摘要： 本文工作是一种实际热力系统参数优化方法的基础预备工作,首先通过等价变换方法,把有限热容热源和工质循环的实际热力系统变换为等价定温热源和等价内可逆卡诺循环热机模型,其次用定常态有限时间热力分析法,求解出热力系统的输出功率、效率、换热器总传热系数与工质的吸热、放热等效温度之间关系式,而后借助无量纲归一化方法给出热机输出功率与效率的关系图,本文工作为后篇的实际热力系统的参数优化提供了理论基础。

关键词： 产品设计   创新思维   综合设计能力  

摘要： 高职类工业设计专业学生在经过专业基础课的学习后,将会进入产品设计这一专业核心课程的学习,该课程主要讲述产品设计的流程和方法,帮助学生运用前期所学专业知识完成某项工业产品的设计开发工作。高职类产品设计课程的教学目标是在课程的不同阶段设置不同的产品专题设计,让学生进行不同的设计实践,以此培养学生的创新意识和软件操作等方面的能力,使其熟悉设计方法和流程,激发学生的创新能力与创造能力,引导学生将设计定位于设计实现的层面,训练其综合的产品设计能力,以满足后续毕业设计教学环节对学生综合产品设计能力的需要,实现学生与日后工业设计相关实际工作的无缝衔接。

关键词： Hydrogen storage   MEPoPA (Modified Extended-Power Pinch Analysis)   Power losses   Renewable energy systems   Sensitivity analysis   PROCESS INTEGRATION   MANAGEMENT STRATEGY   ELECTRIC SYSTEM  

摘要： EPoPA (Extended-Power Pinch Analysis) is a technique to integrate Hybrid Renewable Energy Systems with Battery/Hydrogen storage. Power losses of the storage components due to their inefficiency have not been considered in EPoPA as of yet. This study proposes the MEPoPA (Modified Extended-Power Pinch Analysis) to modify EPoPA to consider the power losses in Hydrogen Storage System components. The MEPoCC (Modified Extended-Power Composite Curve) and MEPoSCT (Modified Extended Power Storage Cascade Table) are introduced as the MEPoPA graphical and numerical tools to determine the minimum targets of Required External AC (Alternating-Current) and DC (Direct-Current) Electricity Sources as well as the Hydrogen Storage System component sizes. The sensitivity analysis is conducted to investigate the effect of various Hydrogen Storage System components, such as the inverter, converters, Fuel Cell, Electrolyzer and rectifier efficiencies, on the Hydrogen Tank Electricity Capacity and the Required External AC and DC Electricity Sources. The graphical and numerical results of the MEPoPA obtained from a case study showed that the system designed by MEPoPA requires 62.19% more out sourced electricity than the system designed by EPoPA. This means that the integration potential of the Renewable Energy System with Battery/Hydrogen storage is decreased with an increase in the power losses of the storage system. (c) 2016 Elsevier Ltd.
