大麻/彩棉交织物蓬松柔软整理

为了提高大麻/彩棉交织物的柔软度,分别选用弱阳离子型柔软剂和阳离子型蓬松片对织物进行处理,以抗弯刚度为主要评价指标.考虑到柔软剂与蓬松片的交互作用,通过二次回归正交试验建立回归方程,确定交互作用下试剂的最佳浓度.通过对处理前后交织物的断裂强力、断裂伸长及手感进行对比分析最后得出最佳整理工艺:柔软剂的质量浓度为7.656...     

Influence of chromium diffusion and different surface finishes on the oxidation behaviour of chromium steels

Abstract

The present contribution is focused on the systematic investigation of the effects of different surface finishes (ground, polished, electropolished) on the oxidation behaviour of chromium steels. The specimens were oxidized in a H2–2.5%H₂O atmosphere at 872 K for 1 h to 100 h. Depth profiles were recorded by secondary neutral mass spectrometry (SNMS) to determine the elemental composition of the oxide scale and the diffusion profiles below the scale. The surface finish was found to influence both the thickness of the oxide scale and the depletion of the selectively oxidized elements.

大麻/彩棉交织物蓬松柔软整理

为了提高大麻/彩棉交织物的柔软度,分别选用弱阳离子型柔软剂和阳离子型蓬松片对织物进行处理,以抗弯刚度为主要评价指标。考虑到柔软剂与蓬松片的交互作用,通过二次回归正交试验建立回归方程,确定交互作用下试剂的最佳浓度。通过对处理前后交织物的断裂强力、断裂伸长及手感进行对比分析最后得出最佳整理工艺:柔软剂的质量浓度为7.656 g/L,蓬松片的质量分数为6.862%。经蓬松柔软处理的大麻/彩棉交织物,硬挺度明显下降,手感丰满、滑糯,柔软度明显增加且强力损失较小。

Application of Infrared Thermography Technique in Building Finish Evaluation

Infrared thermography is a well-established technique for evaluating material properties through thermal measurement. In this paper, the thermographic principle of debonded building-finish system is proposed based on laboratory calibrations. An effective approach is developed to eliminate the disturbance of reflection. The survey results prove that this method is reliable in detecting the debonded ceramic tiles on a building finish. With defective areas appearing differently from well-bonded regions, as a result of their differential transmittance of infrared (IR) radiation, the large surfaces can be rapidly scanned. The proposed approach makes it possible to perform interpretation and analysis with a high degree of accuracy.     

Rahul Mehrotra Associates

Rahul Mehrotra maintains a diverse and active role as an architect, urban activist, writer and teacher. His book Bombay: The Cities Within (1995), with Sharada Dwivedi, is a major enquiry into the history and sociology of India's vivacious and contentious urbanism. He finds his city of practice - Mumbai - a mine for quarrying architectural ideations and languages. Unlike most regions in India that may have to adhere to a conformist cultural agenda, Mumbai offers a conceptual freedom in traversing the traditional and contemporary as the city has its particular plurality in the intertwining epochs, attitudes and ‘coming together and moving apart of the past and present’. Multiplicity is thus axiomatic in Mehrotra's interpretation of the city, although this is transferred in his architecture as a dialogical juxtaposition of public and private, exteriority and interiority, natural and industrial materials, and the traditional and contemporary. Interiority, arising both from reasons of climate and urban conditions, is an abiding theme in Mehrotra's work and is articulated through reified courtyards and walls that also retain an intimate conversation with the larger landscape. From residences to large complexes, he uses these elements with great craft and finesse to create dramatic spaces with changing palettes of materials, colours and phenomenally modulated differences between the exterior and interior.‘In our projects, the approach has been to abstract and interpret spatial arrangements as well as building vocabulary,’ he says. ‘The idea is to combine materials, to juxtapose conventional craftsmanship with industrial materials and traditional spatial arrangements with contemporary space organisation. In short, to give expression to the multiple worlds, pluralism and dualities that so vividly characterise the Asian landscape.’ Copyright © 2007 John Wiley & Sons, Ltd.
