In recent years,rapid urban development has led to capsule hotels,sleep pods,and other tiny sleeping spaces that adapt to people’s fast-paced lives,achieving maximum functionality with a very small ***,due to the small space,human metabolic pollutant(such as CO_(2))is more likely to accumulate,and the air is not easily *** this paper,a full-size experimental platform is set up with three types of ventilation modes to explore the exclusion efficiency of metabolic pollutants and the overall distribution of age of air under these ventilation *** conclusions showed that the mean values of metabolic pollutant exclusion rates for the different ventilation modalities varied very little across the spatial dimensions of the confined space but varied considerably in the area around the *** double-side attached ventilation method was the most effective in removing human metabolic pollutants,especially in the head region(CN≥0.92),while the single-wall attached ventilation method had the best air exchange efficiency(η≥0.85).This suggests an inconsistent distribution of CO_(2) and age of air,which is contrary to general common *** conclusions of this paper can guide the design of ventilation for tiny sleeping spaces.

Fuzzy pattern recognition has been employed to identify some atlas and images of the unevenness of carbide in tool steel. Three models have been constructed. These models were based on fuzzy mathematics theory, as well as fuzzy pattern recognition method. Distribution rule of the unevenness of eutectic carbide in ledeburite steel is proposed in these models respectively.

结合目前中国大量的废弃脱硫石膏无法被合理利用的情况,讨论了钢厂中脱硫石膏制成铁酸钙回收利用的可能性。通过查询热力学数据进行计算研究,探讨石膏分解所需的气氛条件及相应条件下生成物组成。为达到最佳的分解效果,通过热力学计算调整一氧化碳/二氧化碳混合气体各项参数进而控制实验的进行。相关基础实验在实验室中利用现有管式炉进行烧结还原。通过对XRD数据进行半定量分析来确定石膏在不同条件下分解产物的成分组成。结果表明1 050℃为石膏气固反应和固固反应交界点。同时混合气体中一氧化碳体积分数为5%、100 m L/min的气体流量,可以保证气固反应生成氧化钙的同时,硫化钙的量在合理的范围内。实验进一步利用硫酸钙作为钙源制得铁酸钙,为废弃石膏在钢铁厂回收利用提供理论基础。
