由於木塔採用了唐代殿堂內、外分槽的結構形式，用兩層柱圈構成筒體，並逐層加設了層高較低稱為平坐的剛度加強層，再加上兩圈柱子都由下至上向內傾斜對筒體形成環箍力，這些措施幫助木塔抵抗了多次強烈地震而未倒。The reservoir is located at yishan slope area between jinxi fold belt and tianhuan depression, it has the characters of less structural deformation, overlying hydrocarbon genetic center in upper and lower palaeozoic era, growth of high efficient reservoirs and as well as fast lateral changes of reservoir physical properties, it has the condition of forming non structural traps, which is the major area for gas reservoir exploration in the basin
位於晉西撓褶帶和天環坳陷間的伊陜斜坡區，因具有構造變形微弱，上、下古生界生烴中心疊置，高效儲層發育，儲集層物性側向變化快等特點，具備形成非構造圈閉優越條件，為盆地氣藏勘探約重點區帶。The paper has improved the existing lifting - line and lifting - surface design method by including the rake and skew and solving the optimum circulation distribution with the optimum theory. the blade geometry is expressed with b - spline for the lift - surface method. the boundary condition on the blade is transformed to minimize the summation of the square of normal velocities, the fair blade geometry can be obtained by present technique and the design quality is better
改進了現有的升力線和升力面設計方法，在升力線設計中計及槳葉的縱傾和側斜的影響，用優化理論求解最佳環量分佈，升力面設計中用b樣條來擬合槳葉，將物面邊界條件轉化為求法向速度分量的平方最小，由此可得到光順的槳葉幾何形狀，提高和改進了設計質量。The simulation results reveal that water vapor transportation northward is responsible for the generation of the convective instability in south shandong, and the easterly wind from sea, gravity wave and convergence generated by southward invasion of weak cold air in pbl play main role in trigger, transmission and enhancement of convective systems
定性地給出了中尺度對流系統氣流運動的圖像，即：在邊界層，氣流從東南方向斜升流入中對流區，在系統中垂直上升，約在7000米一9000米高空向東北方向流出，形成非閉合的垂直環流。In the upper troposphere, there is no intact asian active center. the troposphere structure of summertime ao is implicated with the horizontal heterogeneity of air temperature throughout the whole troposphere with its center over asian continent, which results in the zonal asymmetry and baroclinic structure of the summertime ao ( especially its asian center ). on the contrary, the correlation between wintertime ao and sea - land thermal contrast confines in the lower troposphere, hence its zonal asymmetry and baroclinity in the lower level
夏季北極濤動的這種結構與對流層整層的溫度水平分佈不均勻性有密切聯系，且這種溫度分佈差異主要體現在亞洲大陸，因而也就使北極濤動的中緯度亞洲中心呈現出比同緯度帶其它區域更為明顯的緯向非對稱性和斜壓性；而冬季北極濤動受下墊面海陸分佈差異影響，其緯向非對稱型和斜壓性質主要出現在對流層中低層，在對流層高層表現出很強的環形模態和正壓結構。Internal waves are a kind of bridge relating the diapycnal mechanical mixing to external sources of mechanical energy : first, internal waves are driven by wind stress and barotropic tide so that large amount of mechanical energy are transported to abyssal ocean with propagation of internal waves ; second, the mechanical energy can directly be cascaded to mixing through instability and breaking of internal waves
內波是外界提供的機械能與混合之間聯系的橋梁之一，一方面風和潮汐通過激發內波，將能量向深海和大洋內區傳遞，另一方面，內波的不穩定和破碎直接將機械能串級到小尺度湍流混合中去。開展傾斜地形上內波的傳播以及內潮的產生等方面的研究對海洋混合過程的參數化以及混合對大洋環流的影響等方面的研究具有重要的科學意義。Engineering drawing has always been labeled as a practical subject. a combination of geometrical, building. mechanical and electrical drawing, it relates between theory and the picture of reality. engineering drawing will provide an accurate and complete ptcture for every object tn terms of shapes and sizes. usually, it is taught using the face - to - face teaching mode even in an odl environment. due to its nature, some students may find difficulty in imagining and interpreting the drawings. however, the availability of sophisticated technology provides the opportunity for the learning of engineering drawing to be enhanced via online. a web - based system for teaching and learning engineering drawing was developed based on a constructivism model. the web - based system is tailored for several topics of engineering drawing such as orthographic projection, sectional view, isometric and oblique drawing at the secondary level. the learning strategy consists of multiple phases beginning with introduction, concept learning, engineering drawing method, application and exercises. during introduction, students will be exposed to an overview of the topic followed by learning of specific concepts. the system provides a learning environment that allows engineering students to view objects from different angles, such as third angle projection and first angle projection as well as views of plans, side and front elevations. after learning about the concepts, students wilt be guided through the various steps in drawing methods for each topic via animations and simulations. learners are able to view any section repeatedly. examples of real application of engineering drawings were also given using graphic, animations and video. to evaluate students understanding, exercises were given at the end of each session
工程制圖一直被認為是一門實踐性學科，其整合了幾何學、建築、力學、電子制圖等，從而將理論與現實圖像聯系起來，工程制圖能為每個不同形狀、尺寸的物體提供精確的、完整的圖像.通常，即使在開放與遠程教育環境中，工程制圖的教學也是通過面對面的教學模式來進行的.由於其特殊性，一些學習者可能難以想象並解釋這些圖像.然而，尖端的技術使得可以通過在線的方式加強工程制圖的學習.研究者基於建構主義模式開發了一個面向工程制圖教學和學習的網路系統.該系統適用於幾種工程制圖，例如展開圖、刻面圖、等角圖和斜角圖.學習過程包括導論、概念學習、工程制圖方法，以及應用與練習等階段.在導論階段，系統為學習者提供了專題簡介，然後是概念學習階段.系統所提供的學習環境允許工程專業的學生從三維透視、一維透視、平面圖、側立面、正立面等不同角度來觀察物體.經過概念學習階段后，系統將引導學生通過動畫和模擬學習每個專題中制圖方法的不同步驟，學習者也能重復觀察任何剖面.另外，還通過圖像、動畫和視頻等方式展示真實的工程制圖應用案例.最後，為了評價學生的理解能力，在每部分內容後面都附有相關的練習分享友人
