Based on th e theories of system optimization and the multi object decision, a mathematical model about the multi object optimization operation of gas pipeline network is established, in line with the demand of urban gas pipeline network operation. A t the same time, an effective solution of the mathematical model is presented. A calculating software about optimization operation is compiled, coupling the actual operation of gas pipeline network. It can be applied to the operation of the gas pipeline network. The software was examined by real examples. The resul ts indicated that 2.13% energy consumption and 3.12% gas supply cost can be reduced through optimization operation.展开更多

文摘2025年2月11日,上海交通大学公共卫生学院汪一心研究团队(Reproductive&Environmental Nexus for Extended Wellness,RENEW Lab)与华中科技大学梅素容教授课题组合作,在环境科学领域高水平期刊Environmental Science&Technology上在线发表题目为“Organophosphate esters,sperm mitochondrial DNA copy number,and semen quality:a longitudinal study with repeated measurements”的研究成果。研究者基于自主建立的前瞻性精子库男性队列(n=1385),探究了精子发育不同阶段多种有机磷酸酯(organophosphate ester,OPE)阻燃剂单独与联合暴露对男性精液质量的影响,以及精子线粒体DNA拷贝数的中介作用。结果发现,不同种类OPE阻燃剂单独与联合暴露均影响男性精子活力、密度、总数、正常形态率和精子线粒体DNA拷贝数,且精子发育处于附睾储存期对OPE阻燃剂的暴露最为敏感。中介分析结果提示精子细胞线粒体DNA拷贝数在OPE阻燃剂暴露致精子发育受损过程中起到了重要的介导作用。该研究结果为OPE阻燃剂暴露带来的生殖健康风险评估提供了重要科学依据。
