相变材料在零能耗太阳能住宅中的应用研究——以国际太阳能十项全能竞赛作品为例 [PDF]

open access: yes, 2019
相变材料具有相变潜热大的特性,能够提高轻型围护结构建筑的热稳定性,改善热环境并且节约能耗,在建筑节能领域受到越来越多的关注。主要介绍了相变材料的概况、主要影响因素以及研究现状,并将相变材料应用于建筑的模式分为两种——被动式应用和主动式应用,同时以历届国际太阳能十项全能竞赛的参赛作品为研究对象,对作品中相变材料的应用进行分类研究,以期对绿色建筑设计起到一定的借鉴作用。国家自然科学基金资助项目(51308481);;福建省自然科学基金项目 ...

An open‐label pilot study on an adsorbent mousse containing adelmidrol in client‐owned cats with feline atopic skin syndrome and associated seborrhoea

open access: yesVeterinary Dermatology, EarlyView.
Background – Besides pruritus and skin lesions, cats with feline atopic skin syndrome (FASS) may have seborrhoea. Hypothesis/Objectives – The aim of this pilot study was to investigate whether an adsorbent mousse containing tapioca starch, adelmidrol and a nonpharmacological antimicrobial complex could decrease FASS‐associated seborrhoea in cats ...

COTDR散射信号相关特性的研究

open access: yesGuangtongxin yanjiu, 2012
在基于相干光时域反射计的分布式光纤温度与应变传感原理的基础上,对不同频率入射光的后向瑞利散射信号在频域上的相关特性进行了分析。用后向瑞利散射的离散模型来说明后向瑞利散射信号在传感光纤中传播的原理,用MATLAB软件对COTDR(相干光时域反射)过程进行了仿真和分析,对不同脉冲宽度的入射信号的功率及相关特性进行了分析研究。结果表明,输入脉冲宽度与频域相关带宽成反比,即传感位置精度与温度或应变精度成反比。

Effect of a ceruminolytic ear cleaner on clinical, microbiological and ear canal microbiome evolution in canine erythemato‐ceruminous otitis externa associated with proliferation of Malassezia yeasts

open access: yesVeterinary Dermatology, EarlyView.
Background – Erythemato‐ceruminous otitis externa (ECOE) is commonly associated with Malassezia spp. and microbial imbalance. Hypothesis/Objective – To assess the clinical performance of an ear cleaner in dogs suffering from ECOE associated with Malassezia spp. overgrowth and to measure its impact on the microbiota. Conclusions and Clinical Relevance –

C6vTIR-PCF基模有效面积数值研究

open access: yesGuangtongxin yanjiu, 2007
用多极方法数值研究了六重对称全内反射型光子晶体光纤(C6vTIR-PCF)在1.55μm波长处基模有效面积与包层空气孔层数、直径、间距和相对孔径的关系。结果表明层数的影响较小,在单一参数变化时有效面积随空气孔直径的变大而减小,随间距的增大而变大,在层数与相对孔径一定时有效面积随空气孔半径与间距的同比增大而增大。
