透过鹏华探析开放式基金的销售策略

我国开放式基金的销售起步不久,虽然已经达到一定的规模,但是基金行业在中国资本市场的地位还十分弱小,其销售状况并不理想.因此,加强营销能力是目前我国基金管理公司面临的挑战之一.本文将以鹏华基金管理公司为例,运用市场营销理论的4P组合策略,借鉴国外成熟市场经验,针对该公司的销售现状进行分析,提出了开放式基金的销售策略.     

Research on consistency measurement and weight estimation approach of hybrid uncertain comparison matrix

The consistency measurement and weight estimation approach of the hybrid uncertain comparison matrix in the analytic hierarchy process （AHP） are studied. First, the decision-making satisfaction membership function is defined based on the decision making＇s allowable error. Then, the weight model based on the maximal satisfactory consistency idea is suggested, and the consistency index is put forward. Moreover, the weight distributing value model is developed to solve the decision making misleading problem since the multioptimization solutions in the former model. Finally, the weights are ranked based on the possibility degree approach to obtain the ultimate order.     

论林肯为维护国家统一做出的努力

在美国联邦面临分裂之时,林肯坚决强调国家主权不容侵害,领土不容分裂,维护国家统一不客质疑。在内战中,他着眼于大局,以国家的整体利益为重,为维护美利坚合众国的统一作出了重大的贡献,并表现出一种坚韧不拔的精神。统一则强,分裂则弱,美国内战的结果为美国成为世界强国奠定了坚实的基础。     

The Difference of the Pulmonary-Artery Pressure of the Migrants from Difference Elevation at the 4636 - 4907 m Altitude

Study Objective： To compare and analyze the changes of the pulmonary-artery pressure of the migrants coming from different elevation in the hypoxic environment of 4636 - 4907 m extreme altitude. To explore the susceptibility to hypoxic pulmonary-artery hypertension （PH） in the subjects from different altitude and profession. Methods： By using Color Doppler Ultmsonography （CDU）, measuring the pulmonary-artery pressure of 207 healthy men, who had continuously being lived and worked at the extreme altitude for more than six months, and then were divided into three groups according to their profession and the altitude of original living place. Results： There was a significant difference in the outcomes of pulmonary-artery pressure from the 3 groups. Conclusions： Altitude of original living place, labor intensity are some of factors that impact the pulmonary-artery pressure of the people who exposure to a hypoxic environment. The pulmonary- artery pressure of person without strenuously physical work experience was more sensitive to hypoxic surroundings than that of labor workers. It was not always the fact at an extreme altitude that the moderate altitude mountaineers were superior to other migrants from a lower altitude or plain. The higher PH was found in the groups of the moderate altitude mountaineers and labor workers. It is unlikely certain that one with PH would surfer from HAPE.     

监控承包人的机会主义质量战略

当承包人机会主义行为的一次性收益大于其长期维护信誉的收益时,他将违背合同义务,从而降低了招标人的效用。首先将工程采购描述为一个三阶段博弈,说明诚实和机会主义两类承包人的质量选择战略,以及机会主义行动的经济学条件。然后,利用优化方法选择了最佳的监控比例和处罚政策,这将有助于增加招标人的效用。     

航天器及部位投影形状不确定性的建模与仿真

在未来空间作战中,航天器将成为重要的作战装备,同时也将是敌对双方重点打击的对象.通过投影形状确定航天器类型或者航天器毁伤部位的毁伤度,可以为及时采取相应的措施提供决策依据.结合航天器的三维空间实体描述,给出了航天器投影多边形的误差带模型以及航天器毁伤部位投影多边形的面积误差模型.通过实例仿真分析得出,通过构建航天器及其毁伤部位多方位投影形状数据库,建立多边形面元不确定性模型,结合先进的计算机技术和人工智能技术,确定航天器类型及其可能毁伤部位的毁伤度是可行的.     

高等学校污水再生利用的途径与效益研究

目的探讨高等学校污水再生利用的可行性。方法以陕西某高校为例,采用类比分析法和效益分析方法。结果某高校除去部分较难处理污水,如冲厕所产生污水、厨房污水等,可用污水为2 528 m3/d,占总污水量的67%,经处理后得到可用水约2 000 m3/d,完全满足该校区1 658 m3/d杂用水量的预算。该校区如果实施污水再生利用,每年可以节省绿化、洗车等杂水费用约52.2万元,20年收益为1 044万元。其污水再生处理工艺适合采用生物接触氧化法。结论在高等学校实施污水再生利用是必要的,而且技术是可行的。     

试论魏晋“深情”及其诗学意义

魏晋时期,伴随着理性世界的转变,人们的感性世界也发生了极大的变化,出现所谓的魏晋“深情”。这种以知识分子为情感主体的“深情”,既不同于《诗经》时代原发性的“民情”,也不同于儒家“发乎情,止乎礼义”的“性情”和道家“有人之形而无人之情”的“天情”,它是知识分子个体生命意识觉醒之后于天地宇宙中寻求心灵安顿和精神自由的情感,即人生和宇宙合而为一的生命超越之情。正是这种魏晋“深情”,把中国诗学引向强调“神与物游”和“情景相生”的抒情道路,并深深地刻上了宇宙情怀。
