解釋
測試數據選擇-
And the choice range of hydration coefficient is determined on calculating mass concrete of foundation in high - rise building. at last, combining the test data with the ansys result, some measures about crack - control in construction are summarized. it can be referred to the study on mass concrete of foundation in high - rise building for interaction between concrete temperature field and soil temperature field considered, choice range of hydration coefficient determined, and measures about crack - control in construction summarized in this paper
最後，結合現場監測的數據和ansys計算的理論值，對高層建築基礎大體積混凝土的溫度裂縫的控制提出了有效的控制措施本文提出考慮混凝土與土壤相互作用的溫度場，確定的高層建築基礎大體積混凝土溫度場計算時的水化系數的取值范圍以及建議的現場溫度裂縫的控制措施，對今後建築工程大體積混凝土的研究具有一定的參考價值。 -
We put focal point on the choice and design that the model of data mining, on the basis of the already studies of abroad and the actual needs of mobile telecommunication company. five data mining models of our mobile telecommunication operation are putted forward : customer value model, customer retention model, fraud detection model, customer segment model and best promotion method model. an online survey system was set up to collect research data, and sas enterprise miner was used to test and appraise these models
本文沒有對的數據挖掘理論及建模方法等作過多的闡述，也沒有對數據倉庫建設方面做過細的探討，而是將重點放在數據挖掘模型的選擇與設計上，在國外的已有研究的基礎上，結合企業調研中企業的實際需要，提出了我國移動通信營業的客戶價值、客戶保持、客戶細分、欺詐識別和促銷方式選擇等五個數據挖掘模型；並建立了網上的問卷調查系統來收集研究數據，在sasenterpriseminer中對模型進行了驗證與評價。 -
It mainly introduced elementary theory of the trade gravity model, the challenge of trade gravity model development facing and trade gravity model ’ s application. and it proposes research steps of this article in the above research foundation : we selects correlation data of our country with 151 main trade partners composing panel data in 1992 - 2003, carries on the test to the gravity model of china ’ s foreign trade, and analyses the choice of export location, in the hope of getting more accurate conclusion, and offering scientific basis for the formulation of our country ’ s foreign trade policies ; the second part, the establishment and test of gravity model about china ' s foreign trade. the text sets up the gravity model which studies china ' s foreign trade in seven regions and examines the actual conditions of china ' s foreign trade flow with panel data
本文共分四大部分，第一部分，貿易引力模型及其應用，主要介紹了貿易引力模型的基本理論、貿易引力模型發展面臨的挑戰和貿易引力模型的應用，並在上述研究的基礎上提出了本文的研究思路:選取1992 - 2003年我國同151個主要貿易夥伴的相關數據組成面板數據，對我國對外貿易引力模型進行檢驗，並對出口區位進行選擇，以期得到更為精確的結論，為我國制定對外貿易政策提供科學依據;第二部分，我國對外貿易引力模型的建立和檢驗，在這一部分按中國的貿易夥伴國分七大區域建立了研究中國對外貿易的引力模型，並運用面板數據對中國對外貿易流量的實際情況進行檢驗。
