与水或低粘性的液体润滑油的代替在许多工业领域里是高度合乎需要的，由于环境、节俭的优点。水的低润滑可能为水力的部件的合适的操作是不够的，并且像钻石的碳(DLC ) 涂层作为稳固的润滑剂电影很吸引人。一个遥远血浆的 PACVD 过程被利用扔 hydrogenated DLC 涂层(交流: H ) 在不同底层上。Microindentation 大小证明涂层坚硬在 35 GPa 附近。Tribological 行为被测试与氧化铝在水和水里执行了的 block-on-ring 评估。wear 率在由激光 profilemeter 测量 wear 体积以后被计算。wear 轨道的词法、组合的分析表明那涂层失败可以由磨料发生穿或分层，取决于底层性质。难、光滑的底层给最好的结果，驱散的氧化铝粒子增加 wear 率。

Spatial Quality of Social Housing for Seniors： Village of the Elderly in S^o Paulo （Brazil）

引用

Journal of Civil Engineering and Architecture 2016年第5期10卷 615-628页

作者： Rosio Fernandez Baca Salcedol Renata Cardoso magagnin Talita Cristina Pereira Architecture Arts and Communication Faculty UNESP (Univ. Estadual Paulista) Bauru 17033-360 Brazil Architecture and Urbanism UNESP (Univ. Estadual Paulista) Bauru 17033-360 Brazil

This paper presents the quality assessment of the built environment in the social housing for seniors ＂Village of the Elderly＂, located in the central area of Silo Paulo （Brazil） and it is the case study analyzed here. This multi-method study aimed to evaluate the quality of the built environment through the following indicators： community public facilities in the neighborhood, accessibility, safety and quality of housing. The results showed that ＂Village of the Elderly＂ was designed to house residents with income of up to three minimum wages, however, for lack of specific technical knowledge on human aging, some problems related to accessibility and safety of residents were neglected. The research contributes to studies on the quality of the ambience of constructed space and the results can support public policies, programs and projects of social housing for the elderly.

关键词： Social housing Social Rental Program built space quality central area.

Spatial Quality Evaluation of Pedestrian Streets

引用

Journal of Civil Engineering and Architecture 2014年第12期8卷 1567-1574页

作者： Renata Cardoso magagnin Maria Solange Gurgel de Castro Fontes Rosio Fernandez Baca Salcedo Architecture Arts and Communication Faculty UNESP--Univ Estadual Paulista Bauru 17033-360 Brazil

This paper presents an assessment of the spatial quality of a pedestrian street located in downtown Bauru, S^o Paulo State, Brazil, from the application of some urban sustainability indicators. Multi-method was used to evaluate the thermal comfort quality of users, urban accessibility and preservation of architectural heritage. The results show that the sustainability indicators, apart from being effective tools in identifying problems, can assist local managers in decision making, planning and monitoring of pedestrian public space. These indicators contribute to a broad diagnosis of the pedestrian street and also the formulation of programs, projects and municipal policies, aimed at providing a better life quality for pedestrians.

关键词： Pedestrian street sustainability sustainability indicators.
