A field experiment was carried out to quantify biological nitrogen fixation (BNF) using the 15N isotope natural abundance method in maize (Zea mays L.) / faba bean (Vicia faba L.) and wheat (Triticum aestivum L.) /faba bean intercropping systems. Faba bean was yielding more in the maize/faba bean intercropping, but not in the wheat/faba bean intercropping. Biomass, grain yield and nitrogen acquisition of faba bean were significantly increased when intercropped with maize, and decreased significantly with wheat, irrespective of N-fertilizer application, indicating that the legume could gain or lose productivity in an intercropping situation. N fertilization inhibited nitrogen fixation of faba bean in intercropping with either maize or wheat, and when used in monoculture. The response of different cropping system to N-fertilizer application, however, was not identical, with competitive intercropping (wheat/faba bean) being more sensitive than facilitative intercropping (maize/faba bean). Intercropping increased the proportion of nitrogen derived from air (%Ndfa) of the wheat/faba bean system, but not that of the maize/faba bean system when no N fertilizer was applied. When receiving 120 N kg/ha, however, intercropping did not significantly increase %Ndfa either in the wheat/faba bean system or in the maize/faba bean system in comparison with faba bean in monoculture. The amount of nitrogen derived from air (Ndfa), however, increased significantly when intercropped with maize, irrespective of N-fertilizer application. Ndfa decreased when intercropped with wheat, albeit not significance at 120 kg N/ha. Ndfa correlated more closely with dry matter yield, grain yield and competitive ratio, than with %Ndfa. This indicates that not %Ndfa, but total dry matter yield (sink strength) was more critical for the legume to increase Ndfa. The results suggested that nitrogen fixation could be improved by yield maximization in an intercropping system.

Ab initio calculations were carried out for system of CFCs (CFC-11, CFC-12, CFC-13) with CO2, and twelve stable configurations were obtained with no imaginary frequencies. To obtain the interaction energies of these complexes, single-point energy calculations with basis set superposition error (BSSE) correction were carried out at MP2/aug-cc-pvdz and MP2/aug-cc-pvtz levels. The analyses of charge transfer and the atoms in molecules theory (AIM) were used to analyze the nature of the interaction. The results of theoretical calculation indicate that there is the weak interaction as well as the presence of C朇l晻昈 type halogen bonding and C朏晻昈 bonds in these complexes, and which provided some information and data for studying environment problem.

导师与研究生之间的交流互动是研究生培养质量的关键影响因素,本研究围绕当前师生互动交流的频率、方式、内容、载体、效果及影响因素等对全国27所高校展开问卷调查。数据统计分析表明:研究生培养目前多以单个师徒指导交流为主,导师组与多导师制具有较高的认可度和期望度;科研课题是互动交流的主要载体,导师通过指导参与科研等方式在治学、能力、修养、职业理想、人生观方面熏陶培养研究生;师生之间互动交流的形式手段多样但偏好不同;大多数师生都能从当前的交流模式中受益,师生互动交流的总体满意度较高,但部分导师因行政事务等挤占导致与研究生互动交流上有心无力,少部分研究生希望导师能在就业与职业发展等方面提供更多指导帮助的倾向需引起重视。影响目前师生互动交流实效的主要因素有:学科专业、指导风格、投入精力、课题经费、交流频率、交流方式等。针对性的提出了改善师生互动交流模式与途径,调整研究生培养的评价指标体系,建设有效的互动交流激励机制等建议。
