从众心理对环保行为的影响研究

环保行为对于维持生态平衡,保护自然环境有着重要的意义,个人并非从小就有环保意识,需要多方面影响才能养成环保习惯。研究了从众心理对环保行为的影响,从积极影响和消极影响两个角度进行分析,政府加大治理力度,通过媒体等手段宣传环保意识,树立典型环保先锋,则会造成积极影响,社会群众会自发地从事环保行为,维持低碳生活;反之周围人缺少环保意识,浪费资源,则个体也会不重视保护环境,甚至为了个人利益做出破坏生态平衡的事情。从众心理对于环保行为有着关键性影响,必须要积极提倡大众养成环保意识,保护环境,从小做起,从个人做起,为其他人树立榜样     

Emission factors of polycyclic aromatic hydrocarbons from domestic coal combustion in China

Domestic coal stove is widely used in China, especially for countryside during heating period of winter, and polycyclic aromatic hydrocarbons （PAHs） are important in flue gas of the stove. By using dilution tunnel system, samples of both gaseous and particulate phases from domestic coal combustion were collected and 18 PAH species were analyzed by GC-MS. The average emission factors of total 18 PAH species was 171.73 mg/kg, ranging from 140.75 to 229.11 mg/kg for bituminous coals, while was 93.98 mg/kg, ranging from 58.48 to 129.47 mg/kg for anthracite coals. PAHs in gaseous phases occupied 95% of the total of PAHs emission of coal combustion. In particulate phase, 3-ring and 4- ring PAHs were the main components, accounting for 80% of the total particulate PAHs. The total toxicity potency evaluated by benzo[a]pyrene-equivalent carcinogenic power, sum of 7 carcinogenic PAH components and 2,3,7,8-tetrachlorodibenzodioxin had a similar tendency. And as a result, the toxic potential of bituminous coal was higher than that of anthracite coal. Efficient emission control should be conducted to reduce PAH emissions in order to protect ecosystem and human health.     

目前国有企业人力资源管理存在的问题与改进对策

目前国有企业在从传统人事管理向现代人力资源管理模式转变过程中遇到了改革受阻、效果不佳、观念落后、定位不高等问题,这些问题的产生主要是由于传统思想认识、落后的工作开发定位等根本性原因.因此,国有企业应采取树立新型大人力资源观念,加强人力资源管理部门自身建设,运用现代人力资源管理手段切实处理好培训开发、激励、评估等关键问题的改进对策.     

Industrial park management in the Chinese environment

In China many investments especially from foreign companies are located in industry parks. However, the general situation and management perspectives of developing Chinese industrial parks are not very clear to the westerners. With the rapid development, industrial parks will play a key role in China's economy, therefore, those issues relating with China's industrial parks need to be further discussed. This paper is one of such efforts. It will review the development of China's industrial parks, including characterizing industry parks in China and discussing the main site selection criteria and important aspects for foreign investors. The main focus of this paper is to discuss the current environmental management practices of industrial parks because such parks have been main sources of pollution. New development strategy for industrial parks, such as eco-industrial development, should be considered and implemented.

西安地铁双线隧道地表沉降预测模型研究

针对西安地铁留核心土、上下半洞开挖、超前小导管注浆加固与水平钢撑锁脚的钢拱架和挂网喷层支护的饱和黄土隧道,根据现场地面沉降监测数据,分析了隧道右线、左线掌子面间隔30m开挖过程中洞顶地表沉降变形的历时变化规律,以及左、右线单洞沉降槽和双线沉降槽的分布特征.结果表明,洞顶地表沉降变形可以划分为初期沉降变形、右线开挖主变形...     

光伏发电有功自动控制技术

进行了两根足尺预应力型钢混凝土简支梁在火灾高温和竖向恒定加载耦合作用下的耐火性能试验,分析了试验梁的温度场分布规律、竖向变形特点和承载性能劣化过程。通过在试验梁端部预设压力传感器,实测了升温过程中梁端部预压力与升温时间的关系曲线。试验结果表明,预压力对火灾高温作用较为敏感,当标准升温100 min时预压力已降至初始预压力的一半,试验中一根梁出现了侧向弯曲变形。因此,对于预应力混凝土结构,火灾高温作用下应考虑构件可能的侧向变形影响。     

基于典型省份对比的我国入境游客流量时间分布集中性计算与差异分析

客流量的时间分布集中性对旅游企业经营管理的季节性调整方略具有重要影响.选取了代表我国东部、西部、北部、南部、中部的5个典型省份的入境游客时间分布数据,分析了游客流量的时间集中性指数和高峰指数的内涵和变化状况,并对集中性指数的差异进行了简要的区域对比分析,为旅游企业季节性对策的确定提供参考.研究表明,客流量月强度指数Rm和中值月高峰指数Pmid较好地反映了客流量时间分布集中性.就区域而言,我国东部游客量的时间分布集中性小于西部,南部小于北部,沿海小于内陆.
