To learn the subgroup structure generated by multidimensional interaction, we propose a novel multiview subgroup integration technique based on tensor decomposition. Compared to the traditional subgroup analysis that can only handle single-view heterogeneity, our proposed method achieves a greater level of homogeneity within the subgroups, leading to enhanced interpretability and predictive power. For computational readiness of the proposed method, we build an algorithm that incorporates pairwise shrinkage-encouraging penalties and ADMM techniques. Theoretically, we establish the asymptotic consistency and normality of the proposed estimators. Extensive simulation studies and real data analysis demonstrate that our proposal outperforms other methods in terms of prediction accuracy and grouping consistency. In addition, the analysis based on the proposed method indicates that intergenerational care significantly increases the risk of chronic diseases associated with diet and fatigue in all provinces while only reducing the risk of emotion-related chronic diseases in the eastern coastal and central regions of China.

为了减少烟气中SO2的排放,提出了对烟气中的SO2进行深冷液化分离的脱硫方法。基于Aspen plus建立了一种深冷脱硫流程,选用SRK(Soave Redich-Kwong)物性方法对流程进行稳态模拟,研究了深冷温度、深冷压力和SO2浓度对深冷液化分离效果的影响规律。搭建了深冷脱硫试验台,进行了试验验证。研究发现,对于SO2质量浓度为1 000 mg/m3的烟气,深冷压力为500 kPa时,深冷温度从-15℃降至-45℃过程中,SO2脱除效率从40.2%增加到73.2%;深冷温度在-45℃时,从500 kPa增加到4 000 kPa过程中,脱除效率从73.2%提高到92.9%;提高SO2浓度有利于提高脱除效率。综合结果表明,深冷液化分离系统具有较好的液化和分离效果。若SO2脱除效率在80%以上时,其工艺参数范围为:深冷温度低于-35℃,深冷压力高于2 000 kPa。
