Metropolitan circle is the result of industrialization and urbanization, which is the embodiment of centralization and radialization when the metropolis is developing to a certainty, in order to advance the space and economy to conform, to form a corporate area, fabricating the new type of metropolitan circle in which the metropolis is the core is new topic for discussion of innovative space structure of the big ciry this paper combine the theory expatiation and demonstration analysis with comprehensive and new statistics data, and theory model, and discusses the all - around regional development in chengdu area from a new angle, ie : using space structure model of metropolitan circle to develop the overall enhancement of strength in chengdu first, the thesis defmitudes the concept, connotation, and character of metropolitan circle, after that, it discusses the formative mechanism of metropolitan circle from the factors such as market, institution and ect moreover, from the practice of metropolitan circle ' s development in ho me and abroad, it summarizes the significance of the metropolitan circle form for the economic and social development, as well as the experience for reference and the problems we should pay attention to = based on these theories and practice, it brings forward the necessity and strategic significance of building metropolitan circle in chengdu, and analysis its possibilities, it also makes a research on the model of this circle, it innovatively brings forth that the double - polar circle structure of central city - sub central city - satellite town should be builded, through the establishment of index system, the sphere of metropolis circle in chengdu can be set which means the central city, sub center city and satellite town are sett it also analysis how to determine the gravity between center city and circumjacent area, and discusses the function orientation of center city and satellite town at last, it briefly analyses the transportation designing of suburb and city which are imperative for constructing the metropolitan circle in chengdu
本文將理論闡述和經驗實證分析與較全面的最新統計資料，以及理論分析模型分析結合起來，從新的角度深入探討成都的區域整體發展，即以都市圈的空間結構模式促進成都整體實力的全面提高。本論文首先明確了都市圈的概念、內涵及特徵，從市場、等因素探討了都市圈的形成機理，並從國內外都市圈的發展實踐中，總結出都市圈這種空間形式所引起的經濟和社會發展的意義所在，以及我們值得借鑒的經驗和需要注意的問題。在此理論和實踐基礎上，提出構建成都都市圈的必要性及戰略意義，分析其可能性；並且對如何構建成都都市圈模式進行了探討，主要是創新性提出構建中心城市-副中心城市-衛星城鎮的雙極圈域結構，並通過指標體系的建立以確定成都都市圈的范圍，即中心城市、副中心城市和衛星城鎮的確定，以及測定中心城市與周邊地區的引力大小，以及對中心城市和衛星城鎮的功能定位進行了探討。 -
In china, with gradual establishment in market economy system, the transformation of core value in moral from “ politics in command ” to “ economical center of gravity ”, people ' s value pursue has changed to utilitarian realism gradually
在中國，隨著市場經濟體制的逐步確立，道德核心價值從「政治掛帥」向「經濟重心」變換，人們的價值追求逐漸轉向功利的現實主義。 -
This thesis is relied on the subject " analysis of prospecting foreground and evaluation of favourable play of oil and gas in santanghu basin " and based on areal geology, gravity, magnetism, electricity, seism, rock - core etc, and it ' s guiding ideology is the plate tectonic theory, the continental dynamics. the new achievements and the new understandings of the international exploitation of oil and gas fields. in light of the elementary analytic principles " integrated, dynamic, comprehensive ", it studies the structural features and the formation and evolution of santanghu basin on the the basis of obtaining abundant first - hand data
本文以「三塘湖盆地油氣勘探前景分析與有利區帶評價」項目為依託，以板塊構造理論、大陸動力學研究以及國際油氣田開發的新成果和新認識為指導思想，以區域地質、重磁電、地震、巖芯等等資料為基礎，獲取扎實的第一手資料， 「整體、動態、綜合」地研究三塘湖盆地構造特徵及其形成演化。 -
The reactor can be shutdown during emergency by cutting off the power supply to the control rod driving mechanism which then causes the control rods to drop down to the reactor core by gravity quickly and thereby stopping the nuclear fission immediately
在需要緊急停堆時， ?須切斷控制棒驅動機械的電源，控制棒便會因地心吸力而快速下墜至反應堆堆芯，立即停止核裂變。 -
The project studied the direct contact condensation behavior of saturated steam on the subcooled liquid in passive gravity injection system. the experiment parameters were as follows : the initial pressure of prz ranged from 0. 2 0. 6mpa and the initial fluid temperature of core makeup tank ranged from 10 80. condensation phenomenon in cmt was observed
