Abstract:
利用Hot disk热常数分析仪测定了压实新疆阿尔泰膨润土在不同条件下的导热性能。探讨了干密度、含水量、孔隙度、饱和度与导热性能的关系,并运用了多种模型对热传导系数进行了预测对比分析。结果表明:阿尔泰膨润土的热传导系数、热扩散系数和体积比热均随着干密度和含水量的增大而增大;相同含水量条件下,均随孔隙度的增大而减小;在饱和度大于20%时,饱和度与热传导系数、热扩散系数和体积比热具有明显的指数关系。通过对比,得到实验所得方程与Kahr模型能较好地预测阿尔泰膨润土的热传导系数。
To analyze the relationship between dry density, water content, porosity, saturation and thermal properties, Hot disk thermal constants analyzer is used to measure the thermal properties of compacted Xinjiang Altay bentonite under different conditions. The test results of thermal conductivity are analyzed by several models. The experimental results show that thermal conductivity, thermal diffusivity and volumetric specific heat increase as the dry density and water content increase, and for the same water content, the thermal conductivity, thermal diffusivity and volumetric specific heat decrease as the porosity increase. When the saturation is more than 20%, exponential relationships between saturation and the thermal conductivity, thermal diffusivity, volumetric specific heat are observed respectively. By contrast, the equation obtained by experiments and Kahr’s model is more suitable for predicting the thermal conductivity of Xinjiang Altay bentonite.

Abstract: 遥感数据具有周期短、信息量大和成本低的特点,在生态水文模型中具有广泛的应用前景。本文从生态水文模型的概念出发,阐述了将遥感技术应用于生态水文模型的必要性,在此基础上总结了遥感在生态水文模型中的应用现状,最后,对遥感在流域生态水文模型应用中存在的关键问题(如遥感数据的不确定性、遥感的时空尺度与水文模型的不匹配、遥感数据与其他输入数据的空间尺度不兼容、模型参数估计与遥感数据同化)进行讨论。随着遥感技术的进步,高光谱、多波段数据的不断涌现,流域生态模拟的输入数据更加丰富和多样化,数据同化技术作为多源数据的融合和集成的重要手段,将极大推动遥感生态水文模型中的应用。
Remote sensing, with advantages of short period, abundance information, low cost, plays an important role in ecohydrological modeling. This paper firstly introduces the characteristics of ecohydrological model and their requirement for remote sensing data. Then the paper provides a perspective on current state of application of remote sensing in eco-hydrological modeling. The key problems of the application of remote sensing in ecohydrological modeling are addressed (i.e., the complex issues of uncertainty, scale mismatching et al.) which may be solved by data assimilation. With the development of remote sensing technology, hyperspectral and multispectral image becomes more and more popular, which will expand the application of remote sensing in ecohydrological modeling.

Abstract:

本研究以辽宁省营口市一户农村家庭为研究对象,利用MCH-383SD CO2浓度/温、湿度记忆仪对其夏季室内外空气品质进行连续监测,以二氧化碳评价分指数对炉灶使用前后对人舒适感的影响进行评价,研究农村炉灶对室内空气品质的影响并探讨其改善方法。研究结果表明:农村炉灶的使用降低了室内空气品质,且不同房间受到的影响各异;通过对示踪气体CO2浓度与换气次数的线性拟合,得出其具有良好的线性相关性,基于本研究提出改善农村住宅室内空气品质的措施
This research targets a rural family in Yingkou City, Liaoning Province, utilizing MCH-383SD carbon dioxide concentration/temperature, humidity monitor to constantly monitor its Indoor Air Quality (IAQ) in summer, evaluates the influence of using stove on human comfort using evaluation of sub-indices of CO2, and studies the impact of rural cooking range on air quality and discusses the approaches to improve the air quality. The result indicates that the utility of rural cooking range decreases indoor air quality and the impact on it varies from house to house; meanwhile, a good linear dependence between the concentration of
