    国家电网公司作为国有大型企业在我国经济建设中承担着重要的角色,2008年国家电网公司的电网投资2475亿元,占整个电网公司全年固定资产投资的96%,目前世界经济处于金融危机的笼罩下,经济发展速度放缓,全球的经济处于不利的局势,在这种情况下,实施电网建设项目时更要特别的注重成本的节约,与传统的成本控制方法不同,全寿命周期成本控制方法着眼于对建设项目整个寿命周期的成本进行分析与控制,力求达到全社会的成本最优。本文对于电网建设项目的成本控制研究就是以全寿命周期成本为理论基础展开的。首先对国内外各领域利用全寿命周期进行成本控制的成果进行分析评述,其次,在此基础上对全寿命周期成本控制进行理论内涵进行阐述...State Grid,as a large state-owned enterprise,plays an important role in economic construction of China. State Grid’s spend 247.5 billion yuan on investing power grid in 2008,it takes up 96% of fixed assets.The world economy is on the cover of the financial crisis at present and economic growth slowed,the world economy is weak.In this condition,we must focus on saving cost in power grid constructio...学位:会计硕士院系专业:厦门大学与厦门国家会计学院会计硕士专业学位联合教育中心(MPACC)_会计硕士学号:X200915702

    电子设计竞赛是提高学生动手能力、加强创新设计能力、增进团队合作等能力的有效手段,同时也能促进高校相关课程的改革。\"电力电子技术\"课程涉及电子技术、控制技术和电力技术,主要内容包括电力电子器件、整流电路、逆变电路、直流-直流变换、交流-交流变频、PWM控制技术及软开关等,课程实践性和工程性都很强。根据\"电力电子技术\"课程特点及存在的问题,提出相应的课程教学改革思路并加以实践,包括将\"电力电子技术\"课程与电子设计竞赛结合,把电赛题目带进课堂,通过案例式教学讲授知识点,积极动员学生参与电子设计竞赛,积累好的作品反馈于课程教学等。结果表明:结合电子设计竞赛的\"电力电子技术\"课程选课学生数有明显提升,参与电子设计竞赛的学生人数和获奖比例有一定提高

    Experience in using a ureterorenoscope in 14 cases

    We carried out studies using an ureterorenoscope in 14 cases, including 13 patients suffering from an ureteral stone. The stone was smaller than 1 cm and existed in lower and middle portion. The other patient had a foreign substance, which was a double J-stent catheter that had been passed into the middle portion of the ureter accidentally. Initially, the size and course of ureter, the position of stone and foreign substance were ascertained using a retrograde pyelogram. The patients were placed in a lithotomy position under spinal anesthesia or epidural anesthesia. The ureterorenoscope was inserted into the bladder through urethra and the instrument was further extended through ureteral orifice and ureteral lumen to the position of the calculus or foreign substance while observing the procedure. Once the calculus or foreign substance was observed, a 4F Pfister-Schwartz stone retriever or forceps was inserted through working channel. After coming in contact with the stone or foreign substance, the matter was removed while observing it with the scope. The foreign substance and 77% of the stones observed were removed by this procedure and the usefulness of the ureterorenoscope was successfully demonstrated in the cases. However, on the other hand, of these 14 cases, 2 (14%) experienced ureteral injury. In one case, the ureter was penetrated by the scope; and in another, injury occurred during the biopsy of the ureteral wall. Therefore, it is our opinion that more careful use of the ureterorenoscope is necessary to prevent these types of injuries

    Queues in rash-hour type were considered. The process of compounding of medicines constitutes a few of flows in hospital pharmacy. With due regard to this process, the hospital pharmacy of medical department in Okayama University in Japan was modelled for computer simulation. A prescription is expressed in list-structure and the simulation program is made in FORTRAN language

    Two significant improvements over the flowcharter, FORTFLOW, were made by drawing flowcharts on a X-Y plotter and by listing the cross-reference tables about statement numbers and variable names. The flowcharts on X-Y plotter were paged for the convenience of programmers. By providing the cross-reference tables, the programs in the flowcharts could be modified more easily

    Flow charts are one of the most important documentations in system developments and maintenance of data processing system. The system for flow charting of FORTRAN programs, FORTFLOW, is prepared, which generate flow charts on a line printer. These charts are useful for program modifications, communications between members of system development group and decrease of development costs. This system helps especially an inexperienced user of a data processing system to understand a problem. FORTELOW are coded in FORTRAN language and are available for FORTRAN users by general purpose electronic computers
