| 1 | 绿色建筑室内空气有机化学污染预评估:研究进展及建议显示文摘随着建筑物可持续发展问题越来越受到关注和重视,绿色建筑概念应运而生,而室内空气质量是绿色建筑体系中的一个重要方面.如何构建'健康、适用和节能'的绿色建筑室内环境,已成为世界范围内尤其是我国的社会和科研热点问题.建材和家具作为室内主要挥发性有机物(VOCs)污染源,其散发特性直接影响室内空气质量.要较为准确地评估室内空气污染物浓度是否达到绿色建筑对室内空气质量的要求,须了解建材的VOCs散发特性.为此,本文介绍了描述室内材料VOCs散发过程的数学模型和相关特性参数的测定方法,分析了绿色建筑室内空气VOCs预评估中可能出现的问题并提出了相关建议. | 黄少丹 熊建银 张寅平 | 2016 | 中国科学:技术科学2016，46，11： | 9 |
| 2 | Labeling of volatile organic compounds emissions from Chinese furniture:Consideration and practice显示文摘Volatile organic compounds(VOCs)emitted from furniture are recognized as a main cause of bad indoor air quality.In European countries and the U.S.,labeling systems for furniture have been established with good effect to address this issue.However,there are problems with these labeling systems.For example,too many VOCs were targeted,and the testing time was too long(7–28 d).Aiming at solving these problems,solutions are put forward to establish furniture VOCs emissions labeling system in China and some practices are introduced in this paper.They are:some furniture popular in the market were tested and main VOCs emitted from these furniture were identified;furniture loading factors in residential homes were surveyed,and reference bedroom and reference living room were established according to the survey results to make emission rate thresholds of furniture;C-history method was developed and applied to testing furniture which could shorten the testing time to 3 d;a reference toluene sample for assessing the precision of the test results of chamber system was prepared.These works are technically helpful for establishing furniture VOCs labeling system in China. | LIU WeiWei ZHANG YinPing YAO Yuan | 2013 | Chinese Science Bulletin2013，58，28： | 4 |
| 3 | 再生水灌溉对草坪释放挥发性有机物的影响显示文摘为探讨城市绿地植物释放挥发物质对生态环境的影响,使用热脱附-气质联用(TDS-GC/MS)分析技术,对再生水及自来水灌溉条件下的3种北方城市绿化主要草种多年生黑麦草(Lolium perenne)、草地早熟禾(Poa pratensis)和高羊茅(Festuca arundinacea)所释放的挥发性有机物(BVOCs)进行测定,得到再生水和自来水2种不同水质灌溉条件下3种草坪草BVOCs的释放规律。结果表明:3种草坪草释放的挥发性有机物BVOCs主要为萜类、烷烃类、醛类、醇类、酯类、酸类和酮类7类,并且使用再生水灌溉与自来水灌溉相比,3种草坪草释放的BVOCs无明显差异。这表明,使用再生水灌溉城市绿地草坪不会对大气组分产生明显影响,再生水可作为城市绿地草坪生态用水的补充。 | 武利玉 孙迎雪 田媛 李科 苏德荣 | 2014 | 草地学报2014，22，3： | 2 |
| 4 | Modeling chemical releases from building materials: The search for extended validity domain and parsimony显示文摘This study aims to systematically evaluate and extend the validity domains of multiple mechanistic models of chemical emissions from building materials. We compare the validity domain of the analytical solution with four numerical solutions for a single layer material with one convective surface and a wide range of chemical properties, material thicknesses, and simulation time. We also develop a parsimonious simplified model, ensuring the widest possible validity domain with minimum simulation time. For diffusion coefficients lower than 10−15 m^(2)/s, accuracy of the analytical solution requires at least 5000 positive roots. The numerical method using uneven discretization and finite difference approximation for the boundary conditions is the best numerical solution. The parsimonious combined D- and K-limited model achieves similar accuracy as the best numerical solution except slight overestimates at the interface between the D- and K-limited zones, while having simpler computations and much shorter simulation time. These models show good agreement against experimental data. This study demonstrates that the complex analytical solution can be well approximated by a simpler model with a wide validity domain, enabling the high-throughput screenings of a large number of chemical-product combinations. | Lei Huang Alice Micolier Henri P.Gavin Olivier Jolliet | 2021 | Building Simulation2021，14，4： | 0 |
