top-bottom effect 中文意思是什麼
top-bottom effect
解釋
頂底效應-
The aggregation method reduces the dimension and the complexity of the micro - system, but the aggregation model is not the copy of the micro - system, so it makes new global properties emerge at the macro - level which is called emergence. in this paper, the concept of the functional emergence and the dynamical emergence are defined. the direction of emergence effect is bottom - up, and there also exists top - down effect which is called immergence
北京工業大學工學碩士論文通過模型的聚合縮減了模型的規模，給系統的分析和研究帶來了方便，但聚合模型畢竟不是原模型的拷貝，所以在聚合模型中會表現出同原模型不同的行為特性，微觀系統中微變量的變化會導致聚合模型不同的行為特性；即低層對高層的影響，這種影響稱為行為突現（ eme ， gence ） 。 -
The effect of cloud on net radiation flux is not the same at the top and bottom of the atmosphere.
雲對凈輻射通量的影響在大氣頂和大氣底是不一樣的。 -
In fluent, the flow field of the tube wall, center, top, middle and bottom of the evacuated solar collector tube can be observed, the temperature - time curve and radial temperature gradient can be obtained, the heat loss of different part can be directly captured. 3. all kinds of effect factors of the flow field and temperature field have been analyzed
通過fluent計算，清楚地觀察到太陽能真空集熱管壁面和中心部分，頂部、中部和底部在各種工況下的流場分佈均不相同；得出了各種工況下的溫度-時間變化曲線，沿軸線方向的溫度梯度；同時還計算了各部分熱損的傳熱流量； 3 -
During the process of setting up the data warehouse, it merges the thoughts of two kinds of design methods ‘ from bottom to top ’ and ‘ from top to bottom ’, develops and analyzes the topics with the multidimensional model, guarantees to implement quickly and obtains investment repayment rapidly. then, on the basis of making actual effect, it increases the application topics gradually, advances step by step, accumulates experience, therefore it will build up an enterprise layer data warehouse progressively
在建立數據倉庫的過程中，融合了自下而上和自上而下兩種設計方法的思想，以多維模型開發分析主題，確保快速實施，迅速獲得投資回報，在取得實際效果的基礎上，再逐漸增加應用主題，循序漸進，積累經驗，由此逐步建成企業級數據倉庫。
