针对不同沥青用量的大粒径透水性沥青混合料(LSPM-30)进行了常规的浸水马歇尔试验、真空饱水马歇尔试验及冻融劈裂试验,结果表明:存在一个最佳的沥青用量,该沥青用量使得LSPM-30沥青混合料的残留稳定度和残留强度比达到最大值;浸水马歇尔试验和冻融劈裂试验对于评价LSPM-30沥青混合料的水稳定性有一定局限性.采用汉堡车辙试验对比分析了LSPM-30,OGFC-16,SMA-13,AC-251这4种沥青混合料的水稳定性,结果表明:LSPM-30,OGFC-16,SMA-13这些骨架嵌挤型的沥青混合料有较好的水稳定性;汉堡车辙试验较适于用来评价LSPM-30的水稳定性. 相似文献

Phosphor‐based polymer composites were prepared using a melt mixing and extrusion method. Morphology, luminescent properties, and Hamburg wheel test (HWT) of synthesized hybrid material were studied using various polymer matrices. The intensities of the luminescence of the strontium aluminates phosphors (SrAl2O4 : Eu,Dy and Sr4Al14O25 : Eu,Dy) were substantially changed when incorporated into structurally and chemically different organic matrices. HWTs were performed to evaluate the durability of the polymers against simulated wheel loads and the effect of these wheel loads on the luminosity of the polymers. The decay slopes of various polymer–phosphor composites suggests that the simulated wheel load of the Hamburg test did not have a profound effect on the luminosity as such but the duration of luminescence was found to be shorter for the polymer–phosphor hybrid after the Hamburg test. © 2009 Wiley Periodicals, Inc.

Branko Kolarevic 《Architectural Design》2015,85(5):128-133
An emphasis on material synthesis is not without its pitfalls and challenges. Here Branko Kolarevic , Professor and Chair in Integrated Design at the University of Calgary Faculty of Environmental Design, alerts us to the dangers of overlooking materials' shifting capacities, which are so often scale dependent, while also disregarding existing materials in favour of the new or novel. As the potential grows for material systems in buildings to become more adaptive and to harness automation, Kolarevic describes some exciting developments that are taking place in dynamic facade design, providing the much-heralded promise of an efficient use of ambient energy. 相似文献

Shifting the focus from futuristic visions, Alfredo Brillembourg and Hubert Klumpner with Alexis Kalagas of interdisciplinary design practice Urban-Think Tank urge us to ‘forget about utopia’, for in the most part the urban environment of 2050 is already built. Architects’ sights need to be set on the sometimes grim and unfolding reality of favelas and the world's informal cities. 相似文献

Separation of liquids from a fine particle suspension plays an important role in many industrial processes. In the last few years, a number of technologies have been developed for the separation of slurries with coarse particle suspensions and intermediate particle sizes. However, separation of fine particles from these suspensions can be difficult and prohibitively costly. Battelle has developed a solid-liquid separation technology that utilizes difference in electrokinetic/acoustic properties to enhance the conventional solid-liquid separation techniques such as vacuum filters and presses. The present paper describes the application of this electroacoustic dewatering technology to Hamburg dredged material. 相似文献

不同立地条件玫瑰香葡萄酿酒品质及香气成分的比较研究 总被引:1,自引:1,他引:0
以山地和平地的玫瑰香葡萄为原料进行酿酒试验,并且对贮藏后葡萄进行酿酒试验。结果表明:山地葡萄的酿酒品质明显好于平地,而贮藏以后则以平地葡萄的酿酒品质较好,采用溶液萃取法提取葡萄酒中的香气成分,用GC/MS法进行分离测定,并对其主要香味化合物进行了分析比较。 相似文献
