The essence of circular economy is ecological economy , guided under the principle of " reduce , reuse , recycle " , the bringing up of circular economy contribute a lot in finding solution of problems about environment and development , it is the optimum way in sustainable development in present day , a objective demanding when the economy development reach a certain level , and a chosen developing strategy of our country in the 21st century as a whole . the establishing of a circular economy is a complicated systems engineering , which needs the participation from the government , enterprises , sciences , publics and any aspects of the society , with the help of policy and legislation , with the encourage and guidance of marketing measure , building up a circular economy developing model gradually from small business , industrial parks and social communities 循環(huán)經(jīng)濟是一種建立在物質(zhì)不斷循環(huán)利用基礎(chǔ)上的經(jīng)濟發(fā)展模式,要求經(jīng)濟活動按照自然生態(tài)系統(tǒng)的模式,組織成一個“資源?產(chǎn)品?再生資源”的物質(zhì)反復(fù)循環(huán)流動的過程,循環(huán)經(jīng)濟的本質(zhì)是生態(tài)經(jīng)濟,以“減量化、再使用、再循環(huán)”為基本指導(dǎo)原則,循環(huán)經(jīng)濟的提出是人類在解決環(huán)境與發(fā)展問題上的巨大進步,是當(dāng)今世界解決可持續(xù)發(fā)展問題的最佳途徑,同時也是我國經(jīng)濟發(fā)展到一定階段的客觀要求,也時我國21世紀(jì)發(fā)展的戰(zhàn)略選擇。
Firstly designers start with problem , and select one or more patterns of evolution related the system , and then select included paths of evolution . secondly designers determine the state - of - art of product in the selected paths of evolution . finally referring to the engineering examples , designers decide the new principle of the product , which is the solution of problem 設(shè)計者從問題出發(fā),首先選擇一種或多種與系統(tǒng)相關(guān)的進化模式,其次在進化模式下選擇進化路線,之后在進化路線下尋找產(chǎn)品目前的狀態(tài),及可能移動到的新結(jié)構(gòu)狀態(tài),參照已有的工程實例,確定在新的結(jié)構(gòu)狀態(tài)下產(chǎn)品的工作原理,該工作原理即為問題的解。
As a special industry which operates currency capital , bank industry itself is a high risk one . as china c . b during the turn - rail period , for the country ' s planning economy to market - economy transition is underway , its resourses allocation relies on from fiscal department to bank . the risks of state - owned enterprises are financialized . in addition to many factors such as system , policy and so on , commercial bank system has accumulated huge risk , for one direct and realistic expression is a huge sum of undesirable assets . these underlying risks hinder the development of c . b itself seriously and weaken its competitive capability , what is more is that it has obstructed economic continuing and fast development , perhaps even , arouse serious economic crisis . so , it is a pressing and important problem that how we obliterate existing risk and prevent potertial risk . but the solution of problem is usually based on recognizing it correctly . therefore , the stressing point of the thesis lies in analyzing actuality , cause and survey of c . b risk during turn rail period 銀行業(yè)作為經(jīng)營貨幣資金的特殊行業(yè),其本身就是一個高風(fēng)險的行業(yè),在我國現(xiàn)階段由于社會資源分配由財政依賴轉(zhuǎn)向銀行依賴,國有企業(yè)的風(fēng)險金融化,加上體制和政策方面的諸多因素的作用,商業(yè)銀行系統(tǒng)積累了巨大的風(fēng)險,最后直接而實際的表現(xiàn)即是巨額的不良資產(chǎn)。它是銀行其他風(fēng)險最終表現(xiàn)為信用風(fēng)險后的物化載體。這些潛在的風(fēng)險一是嚴(yán)重的妨礙了商業(yè)銀行本身的發(fā)展,削弱了其競爭力;更為嚴(yán)重的是它阻礙了經(jīng)濟的持續(xù)快速發(fā)展,甚至有可能引起嚴(yán)重的經(jīng)濟危機。
Gagne ' s theory of knowledge classification , this paper also makes an active research into the tactics teaching and regular teaching , which help solve the problems in high school physics , aiming to clarify the importance of seeking the solution of problems from their presentation and offer the " asking & answering teaching mode " to both tactics teaching and regular teaching )的知識分類理論為依托,根據(jù)不同類型的知識學(xué)習(xí)的過程和條件的差異,對中學(xué)物理中問題解決的策略教學(xué)和規(guī)則的教學(xué)進行了積極的探索,力求闡明問題表征對問題解決的意義,提出策略教學(xué)的問答式教學(xué)模式,以及規(guī)則教學(xué)的問答式教學(xué)模式。
