Determination of the width of the transition layer between the crystalline and amorphous zones in nylon 1010 by SAXS

The width of the transition layer between the crystalline and amorphous zones in nylon 1010 was determined by SAXS with point collimation and long-slit collimation, respectively. The width of the transition layer, E, was found to be 1.7 nm. The results show that the width of the transition layer is independent of crystallinity.

Daily impact of climate on the pattern of urban family life : Indigenous courtyard houses of Baghdad regions of the hot-dry climates Part I: Daily shifts or daily movements in summer

During the day, there are considerable variations in the climatic factors prevailing in these regions. This is especially so during the 24-hour daily cycle of the long, hot and dry summer (mid-May to midOctober). Such climatic conditions have had a considerable impact on the daily living pattern of family life in the same season, particularly in the urban areas. During the same 24-hour cycle, they have compelled the inhabitants to shift their living activities both vertically in section and horizontally in plan; they do this in pursuit of more acceptable, if not, desirable internal thermal environmental ambience.

粉末涂层抗冲击缺陷分析

讨论了粉末静电涂装中出现的涂层抗冲击试验缺陷，通过设计实验寻找造成该缺陷的原因，揭示了产生涂层起皱和脱离基材的原因是钢板与磷化液之间的匹配性差。通过提高磷化液的游离酸酸度解决了该问题。从理论上推出了游离酸与附着力之间可能的关系：游离酸影响磷化膜与基材的结合力，或影响形成的磷化膜的形态。
