Effects of upholstery materials on the burning behavior of real‐scale residential upholstered furniture mock‐ups

Fire spread and growth on real‐scale four cushion mock‐ups of residential upholstered furniture (RUF) were investigated with the goal of identifying whether changes in five classes of materials (barrier, flexible polyurethane foam, polyester fiber wrap, upholstery fabric, and sewing thread), referred to as factors, resulted in statistically significant changes in burning behavior. A fractional factorial experimental design plus practical considerations yielded a test matrix with 20 material combinations. Experiments were repeated a minimum of two times. Measurements included fire spread rates derived from video recordings and heat release rates (HRRs). A total of 13 experimental parameters (3 based on the videos and 10 on the HRR results), referred to as responses, characterized the measurements. Statistical analyses based on Main Effects Plots (main effects) and Block Plots (main effects and factor interactions) were used. The results showed that three of the factors resulted in statistically significant effects on varying numbers of the 13 responses. The Barrier and Fabric factors had the strongest main effects with roughly comparable magnitudes. Foam was statistically significant for fewer of the responses and its overall strength was weaker than for Barrier and Fabric. No statistically significant main effects were identified for Wrap or Thread. Multiple two‐term interactions between factors were identified as being statistically significant. The Barrier*Fabric interaction resulted in the highest number of and strongest statistically significant effects. The existence of two‐term interactions means that it will be necessary to consider their effects in approaches designed to predict the burning behavior of RUF.

在传统中探寻当代海报的本土设计

在设计国际化的影响下,中国现代视觉设计中充满了受西方影响的视觉语言,“国际化”视觉符号的泛滥与“本土化”视觉语言的失语视觉现象非常突出。作为当今社会人与人交流载体的海报设计,要走出一条“民族个性”的道路,就必须根植于民族文化土壤中,向传统学习,并进行具有创造性的转化,使传统文化符号在当代海报设计中既具有“民族个性”又有“时代性”,这样,我们海报设计才能真正走“国际化”。

广州沙边窑出土窑具及瓷器化学组成研究

利用能量色散X射线荧光光谱仪,对广州沙边窑出土的窑具、青釉、酱釉瓷进行成分分析。结果显示,样品的胎都使用了含铝较高的原料,窑具中杂质较多,而瓷胎中还含有一定量的钾。瓷釉中的钙和钾含量相近,同为主要助熔剂,所以瓷釉多为钙碱釉。通过与西村窑同类型瓷器样品成分的比较,发现二者虽具有相似的制瓷工艺,但西村窑产品的胎、釉具有明显的高钠特征。
