Abstract: 以不同淹水时长为唯一影响因子,以香蒲(Typhaorientalis)和水稻(OryzasativaL.)为宿主植物,选用Glomus属的3种AM真菌(F1菌:Glomusintraradices;F2菌:Glomusversiforme;F3菌:Glomusetunicatum),研究淹水时长对3种AM真菌侵染2种湿地植物的影响,以期为阐明淹水对湿地植物AM结构与功能的影响提供参考.结果表明,淹水时间越长,3种AM真菌对2种植物的侵染率越低;相同淹水时间下,F3菌对香蒲、F1菌和F2菌对水稻的侵染率高于其他菌.3种AM真菌的侵染结构分析表明,菌丝侵染是2种湿地植物形成AM的主要途径,而丛枝和泡囊贡献较小;淹水时间越长,香蒲的菌丝侵染比例越高,但水稻的菌丝侵染比例没明显变化规律;淹水时间越长,2种植物的丛枝侵染比例越低,不淹水时最高.AM真菌产孢数分析表明,淹水时间越长,AM真菌的产孢数越多;相同淹水时长下,F3菌产孢数最多.2种植物的湿重变化表明,3种AM真菌在长时间淹水条件下仍能明显促进香蒲地上和地下部分的生长,但对水稻的生长影响不明显.本研究表明,淹水时长影响AM真菌对湿地植物的侵染水平和侵染结构,淹水条件下AM真菌对湿地植物生长仍有促进作用,但这受宿主植物对AM真菌的菌根依赖性影响.所以,在湿地植物上应用AM真菌时,应考虑植物的菌根依赖性和淹水时长对接种效果的影响.

Al原子K壳层光电离的理论研究
Theoretical studies on the K shell photoionization processes of Al atom

Abstract: 基于多组态Dirac-Fock理论方法及其相应的GRASP2K和修改后的RATIP2012程序包,计算了极化光子入射Al原子K壳层光电离截面,并利用最新发展的RPI-E计算程序研究了K壳层光电子角分布,重点讨论了辐射场的非偶极项对光电离截面和光电子角分布的影响.结果表明,在入射光子5000eV能量范围内,辐射场的非偶极效应对光电离总截面的影响可以忽略不计.随着入射光子能量的增加,辐射场的非偶极效应对光电子角分布的影响越来越大,入射光子能量在5000eV,一级非偶极参数 的数值达到1.5.
Based on the multiconfiguration Dirac-Fock method and the corresponding packages GRASP2K and the modified RATIP2012, the K-shell photoionization cross sections of the Al atom have been calculated with polarized incident light, as well as the newly developed RPI-E has been used to study the angular distribution of the K shell photoionization. Special attention is paid to the effects of the non-dipole term of the radiation field on the photoionization cross section and the photoelectron angular distribution has been discussed. The results show that the influence of the non-dipole effect of the radiation field on the total photoionization cross section can be neglected in the range of the incident photon 5000eV energy. With the increase of the incident photon energy, the non-dipole effect is more and more important for the photoelectron angular distribution.The value of the first dipole parameter is 1.5 when the incident photon energy is 5000eV.

Abstract:
针对深圳福田供电局提供的PMS台帐和图形信息以及SCADA数据存在质量问题以及对应关系不一致的问题,提出了一套基于智能规则的数据校验与修复方法。可以实现对电网拓扑结构,设备电气参数,PMSSCADA一致性的校验与修复。经过修复的数据便由无法适用配电网高级分析的生数据转化为满足高级分析需求的熟数据,可以极大的推动配电网自动化水平的提高以及评估、规划工作的日常化。通过对深圳福田供电局的实际数据的校验与应用表明,本文的方法能够满足实际评估工作的要求。
For solving the quality issues and inconsistency problems of the accounting & graphical data from PMS and the data from SCADA of Shenzhen Futian Power Supply Bureau of China, a set of data verification and repair methods based on intelligent rules is proposed in this paper. Applying these methods can check and repair the data of network topology, device electrical parameters and the data consistency of PMS and SCADA. The proposed methods can convert the raw data into cooked data to meet the requirements of advanced analysis of distribution network; thus the improvement of distribution network automation and the routinization of assessment and planning of distribution network can be greatly promoted. The actual data validation and application of Shenzhen Futian Power Supply Bureau show that the methods provided in this paper can meet the actual requirements of distribution network evaluation.

Abstract: 与购物中心迅速发展的势头相比,国内对购物中心内消费者行为的理论研究则显得相对滞后。本文涵盖了不同国家有关购物中心消费者行为研究的理论和文献,从消费者心理和行为的角度,分析与传统环境的消费行为相比,购物中心消费者行为的特点,购物中心环境对消费者行为的影响,以及消费者对购物中心环境的期望,并结合国内社会环境和消费者心理的特殊性,提出中国购物中心消费者行为的未来研究方向。
Shopping mall is becoming one of the most favorite destinations for different kinds of consumers, but the research about Chinese consumer behavior in shopping mall seems a little bit hysteretic. The emphasis of our review is to classify the researches in order to give readers a straightforward direction of present studies (in nearly 20 years). The primary purpose of this review is to describe the researches about the development of shopping mall, characteristics of consumer behaviors in shopping mall, how consumer behavior will be influenced by shopping mall atmosphere and customer expectations on the environment of shopping mall. Combining with domestic social environment and the particularities of consumer psychology, we give some suggestions to further research about consumer behaviors in shopping mall in Chinese circumstance.

Abstract:
CBA联赛是国内篮球运动员提升竞技水平和积累比赛经验的大舞台,而随着CBA联赛市场化和职业化的深入发展,CBA联赛19支球队纷纷引进了外籍球员以期提高球队的竞技水平和联赛成绩,也希望外援的加盟能在一定程度上推动国内球员的进步。就在CBA联赛如火如荼发展之际,中国男篮在近几年的亚洲大赛上屡次铩羽而归,甚至失去了“亚洲霸主”的地位,中国男篮竞技水平下滑的背后折射出的是CBA联赛人才造血能力和青少年球员培养方面的不足。本文从2014~2015赛季CBA联赛国内球员与外援竞技水平的对比分析出发,利用一系列统计分析方法,层层深入地分析了国内球员与外援竞技水平差异的状况,总结出国内球员竞技水平的现状,并以此为根据提出了推动CBA联赛国内球员发展和进步的相关建议。
CBA league proves to be a good stage for domestic basketball player to enhance their athletics level and accumulate game experience. With the further development of marketization and professionalization of CBA league, foreign players have been invited by 19 CBA teams, aiming at improving their competitive level and team performance, also hoping to promote the athletics level of domestic players to some extent. Although recent years have witnessed the prosperous development of CBA league, Chinese men’s basketball team has not been endowed with good performance: repeated failures in Asian Champions and even losing the status of “Asian hegemony”. The declining competitive level of Chinese men’s basketball team reflects the lack of talent players and the defect of cultivation of youth players in CBA league. Based on the comparative analysis of athletics level of domestic and foreign players in 2014-2015 CBA season, by means of a range of statistical methods, the obvious gap of their athletics level has been analyzed from simple to complicated and the current athletics level of domestic players has been concluded in this paper. Then, relevant suggestions have been proposed for the progress and development of CBA domestic players according to the above analysis.

Abstract:
近二十年来,CBA联赛(中国男子篮球职业联赛)在品牌价值、市场开发、传播影响力、管理体制、球队建设和青少年培养等方面取得了令人瞩目的发展,极有可能发展成为紧随NBA联赛(全美职业篮球联赛)之后的全球第二大职业篮球联赛。同时,以NBA联赛为参照,CBA联赛在数据统计方面逐步完善,这为篮球专业人士和广大球迷提供了深入研究CBA联赛的机会。本文综合运用一系列统计研究方法对2014~2015赛季CBA球队常规赛成绩的影响因素进行了实证研究。结果表明,CBA球队的整体攻防能力是决定球队常规赛成绩的最核心因素;CBA常规赛存在明显的主场优势,球队在主客场比赛的成绩差异显著地体现在球队的各个方面;CBA联赛各球队在竞技篮球技术层面还存在明显的不足。
In recent twenty years, the CBA league (China Men’s Professional Basketball League) has achieved remarkable development in the fields of brand value, market exploration, communication influence, management system, team building, youth training and so forth. It is likely that the CBA league will be the world’s second largest professional basketball league, immediately following the steps of the NBA league (National American Professional Basketball League). According to the NBA league, the system of data statistics of the CBA league has been improved gradually, and professionals and amateurs have been endowed a chance for further study of the CBA league. In this paper, empirical research has been made by a series of statistical methods for studying the influence factors of CBA teams’ performance in 2014-2015 regular season. The results show that, the overall offensive and defensive capabilities of CBA teams are the core elements of the team performance in regular season; CBA teams have been endowed obvious home advantages and the team performance difference between home and guest games has been significantly reflected in some aspects; some obvious deficiencies of basketball technology still exist in CBA teams.
