With the development of society , quite a few environmental problems had emerged , there had been several environmental evaluations in the world , but their objects were almost about air , water and suchlike , while energy was seldom involved . in order to find out fundamental reason of the interaction of the environmental issues and the consumption of energy , emergy analysis ( ema ) was applied in this thesis 面對當前在人口、資源、環境與經濟發展之間的矛盾,國內外出現了多種環境評價體系和研究方法,但由于這些評價體系大都是針對某種具體對象而提出的,例如對大氣質量的評價、對水質的評價等,而對環境與能量消耗相互影響的底層原因及定量化很少涉及。

The ambulance command training school provides a 26 - week basic training programme for recruit ambulancemen on ambulance aid , anatomy and physiology , mountain rescue and physical training ; cardiac - pulmonary resuscitation training for the staff of homes for the elderly , schools , community organisations and other government departments ; and paramedic training at emergency medical assistant ( ema ) ii level to ambulance personnel 救護訓練學校為新聘的救護員開辦26個星期的基本訓練課程,內容包括救護學醫療急救、解剖和生理學、登山拯救和體能鍛?等。該校也為安老院、學校、社區組織及其他政府部門的員工提供心肺復蘇課程,以及為在職救護人員提供二級急救醫療助理水平的輔助醫療訓練。

Compared the present environmental evaluation , and pointed out the imperfection ; analysis the relation between the environmental problem with the energy from two aspects of environment and economic with energy and environment . 2 . come up with the energy accounting structure of eco - economic system , and use ema to calculate the emergy of the five flows of beijing from 1995 to 2000 本論文的研究工作主要包括以下幾個方面: ( 1 )分析了現有的環境評價體系中的不足之處,以環境協調性評估lca的評價方法為例,逐項列出系統能量損耗,從環境與經濟、能源與環境兩個方面來探討能源與環境相互作用的機理。

There are mainly two ways of theoretic study on gmr in magnetic granular alloys . one is to extended the quantum or quasi - classical treatments of gmr in multilayers to the one in magnetic granular systems . the other is a phenomenological method which adopes effective medium approxiation ( ema ) and two - channel model directly 顆粒復合膜中巨磁阻效應理論研究主要有兩條途徑:一條是將多層膜中巨磁阻效應的量子方法和半經典方法推廣到顆粒復合體系,另一條是直接利用有效介質理論和雙通道模型的唯象方法。

Ema , assumes the components distributed in highly random fashion , is a useful method to treat the transport properties of granular composites , and the effective conductance of composites could to be derived sell - consistently by substituting the actual enviroment of the studied grain with effective medium 有效介質理論能夠有效地處理顆粒復合體系的輸運性質。它假設體系中各種組分以顆粒形態隨意分布,用等效介質替代被研究顆粒外部的介質分布,并且自洽地求出體系的等效電導率。
