The preparation process parameters of intercalated meltblown nonwoven materials are complicated, and the relationship between process parameters, structural variables, and product performance needs to be investigated to establish a good mechanism for product performance regulation. In this study, we first used Wilcoxon test and Pearson correlation analysis to investigate the effect of intercalation rate on structural variables and product performance. Then, regression models were constructed to predict the values of each structural variable under different combinations of process parameters. Finally, we constructed a multi-objective constrained optimization problem based on the stepwise regression model and the product variable conditions. The problem was solved using the NSGA-II algorithm. The optimal was achieved when the acceptance distance was 2.892 cm and the hot air speed was 2000 r/min.

基于UNCTAD发布的班轮双边运输连通性指数和港口运输联通性指数,分别构建以国家/地区和港口为节点的复杂网络,分析海上丝绸之路港口网络的层次结构及其时空演变,研究发现:(1)港口网络形成以中国、东南亚、东北亚、欧洲为中心的格局,整体呈现小世界性,符合“核心-边缘”理论;(2)在层次结构方面,当以国家/地区为节点时,可分为核心区、半核心区、半边缘区和边缘区四类,当以港口为节点时,可分为枢纽港、半枢纽港、干线港和支线港四类;(3)在港口网络时空演变方面,124个港口形成的八个子网络中,中国、东南亚、欧洲、北非、撒哈拉以南非洲子网络与整体一致,呈现分散化、均衡化趋势,南亚、西亚子网络处于波动调整阶段,东北亚子网出现集聚化趋势,并且各港口子网络的空间自相关性较强,中国、东北亚、东南亚的核心地位得到巩固;(4)港口网络演变受到港口合作机制、港口政策与战略、港口技术、枢纽港规模效应和极化效应等影响。该研究为推动海上互联互通、开展港口合作、优化班轮航线布局提供理论依据。
