面向制造的板级电子电路产品多信息模型研究

Most electronics products use PCB to carry electronic circuits. This paper classifies information contained in PCB-based electronic circuits into several models: geometry model, physics model, performance model and function model. Based on this classification, a multi-information model of product is established. A composite model of product is also created based on object-orientation and characteristics of the product. The model includes a 3D geometry model, a physics model with integrated information that can be divided into microscopic and macroscopic information, a generalized performance model and a function model that are from top to bottom. Finally, a multi-unit analysis is briefly discussed.

法律保护、控股股东与公司绩效分析

我国上市公司具有典型的股权集中特征,研究控股股东行为对于改善我国公司治理具有重要意义。控制权收益是控股股东最大化自身利益的载体。现实决策中,控股股东往往需要权衡公共收益和私人收益哪一个更有利于实现自身利益最大化。文章从法律保护角度出发,以控制权收益为切入点,构建了一个研究控股股东行为的分析框架。结合我国控股股东的实际情况,将该框架进一步具体化,用来解释我国国有控股公司与民营控股公司的绩效差异之谜。     

鲁迅的责任感

鲁迅的责任感是他情感体系中的一种根本情绪。这种责任感表现在家庭、社会、教育、创作等几个方面。同时,责任感的产生也是伴随时间积累而不断萌发和深化的,求学生活的影响、越地文化的哺育、社会实践的锻炼、中外典籍的熏陶都共同作用于鲁迅责任感的产生过程。鲁迅的责任感对于他个人的生命历程、社会发展和民众思想都有重大的意义,这种责任感成就了鲁迅的伟大,也成就了伟大的时代和拯救了危机的民族,可谓意义深远。     

数据中心节能环保研究

随着业务的增长,服务器数量的增加,大型数据中心的能耗成本也迅速增加,并有赶超硬件成本的趋势.因此,数据中心运营商除采用节能环保的硬件外,还在电源管理技术方面进行优化,但单凭硬件优化方案还难以挖掘潜力.包括硬、软件在内的所有相关因素都应当考虑,才能使能效最大化.我们就能效与硬件和软件等相关因素进行分析,讨论了数据中心节能的各种途径,提出了构建节能环保、低能耗的绿色数据中心的建议.     

＂Turkish Five＂：Their Contributions to Contemporary Piano Music and Piano Education in Turkey

First musicians using polyphony and homophony in their compositions can be seen during the 19th century in Turkey. These talented amateur composers, who worked in simple forms, such as marches or educational music, were not actually professional composers but either orchestral or choral directors. Later, during the Republic period （after 1923）, ＂Turkish Five＂ emerged. ＂Turkish Five＂ consisted of professional composers who were educated in Europe and learned western musical forms. These musicians, according to their birth years, are Cemal Resit Rey （1904-1985）, Hasan Ferit Alnar （1906-1978）, Ulvi Cemal Erkin （1906-1972）, Ahmet Adnan Saygun （1907-1991） and Necil Kazan Akses （1908-1999）. ＂Turkish Five＂ achieved important accomplishments and did significant contributions to Turkish contemporary music in 30-40 years with their efforts. While doing this, they used over 500-year old musical legacy of the West. At the beginning, these musicians used Turkish folk tunes and their rhythmic and modal system, however, later, they began to use ＂impressionism＂, ＂neo-classicism＂ and finally ＂atonalism＂ in their music. In the current study, the contributions of ＂Turkish Five＂ to contemporary Turkish piano music and their approaches to piano education were examined via literature review. After an extensive research with the literature on the topic, the researcher has interviewed with six piano teachers from different music institutions in Turkey （including two schools of time arts, two conservatories and two music teacher training schools）. During these interviews, the contributions of the ＂Turkish Five＂ were examined based on ＂relativity＂ and ＂local to global＂ principles in education, and the researcher has searched for the ways to use more of their music in piano education through the interviews. Therefore, the main purpose of the study was to discover ways to implement more of the music by ＂Turkish Five＂ in piano education in Turkey and to ffmd solutions fo
