高科技、高投入、高风险、长周期的航空产品是一个国家工业水平和经济发达程度的重要标志之一。由于种种历史原因,我国民用航空产业发展相对缓慢。在西部大开发方针指引下,充分发挥陕西航空工业的优势,集中全行业资源和人才,发挥"哑铃型"研制模式,两头集中在陕西,并组成符合市场经济规律的股份公司,有利于民用支线飞机尽早提供给用户,成为21世纪初中国航空人应肩负的历史使命。文章浅析了如何发展支线飞机,以引起各方重视。

This study aims to explore the prevalence and determinations of physical inactivity among hospital employees in Shanghai, China. A cross-sectional study of 4612 employees aged 19 to 68 years was conducted through stratified cluster sampling from different classes of Shanghai hospitals in 2011. The total physical activity was evaluated using the metabolic equivalent according to the Global Physical Activity Questionnaire. Among the participants, 38.5%, 32.3%, and 64.6% of the employees are inactive at work, commuting, and taking leisure time, respectively. Up to 41.8% of the men and 37.8% of the women (P = 0.012) are physically inactive. When the age and educational level are adjusted, male doctors and medical technicians show a higher percentage of physical inactivity than male workers in logistics (P = 0.001). Among females, employees who are working in second- and third-class hospitals show a higher proportion of physical inactivity than those who are working in community health care centers. Logistic regression analyses show that the odds ratios (ORs) of leisure-time physical inactivity associated with the intensity of physical activity at work are 2.259, 2.897, and 4.266 for men (P<0.001) and 2.456, 3.259, and 3.587 for women (P<0.001), respectively. The time during commuting activities is significantly associated with leisure-time physical inactivity in either sex (OR= 2.116 for men and 2.173 for women, P<0.001). Hospital employees, particularly doctors and medical technicians, show a higher proportion of physical inactivity than other inhabitants in Shanghai. The time and intensity of activity at work and commuting are associated with leisure-time activities.

能源与经济社会、生态环境协调发展始终是我国面对的重大议题之一。虽然各地区在能源与经济社会、生态环境的协调发展上取得了一些成绩,但区域发展差异显著,区域内存在不同类型的矛盾和问题。因此,必须因地制宜推进能源革命。本文根据中国工程院重大咨询项目“推进能源生产和消费革命战略研究(三期)”主要成果,阐述了以区域能源革命为抓手协调推进能源革命与区域发展的重大意义,提出了因地制宜推进能源革命的战略思路,重点针对京津冀、长江三角洲、珠江三角洲、老工业基地(东北及山西)、中部地区、能源富集地区(新疆及能源“金三角”地区)、西南地区等区域提出了加强能源革命顶层设计,明确我国能源中长期发展战略目标和重点任务;明确区域能源革命的功能定位,形成统筹协调推进区域能源革命的良好格局;加强区域能源革命试点,通过改革办法加快探索形成推动能源革命的高效机制;明确区域能源革命实施责任和考核监督机制,确保区域能源革命取得预期效果等战略举措及对策建议。
