From studies of these characteristics of structures, palaeontology, drilling, well logging, seismic profile, salt chemistry and lacustrine sedimentary system, it is recognized that the new characteristics occur in of section pukou and in huaiyiri sag, and the huge thickness of salt rocks is formed by the crust salt materials upwelling along deep fracture in the form of hot bittern and entering lacustrine basin in this area
通過該區構造、古生物、鉆井、測井、地震、鹽巖化學及湖盆內沉積體系等特徵的研究，認為淮陰凹陷浦口組二段和三段的沉積構造有其特殊性，巨厚的鹽巖層是殼深部鹽類物質沿深大斷裂上涌以熱鹵水形式進入湖盆的結果。The main conclusions are as follows ; firstly, under the influence of three phases of episodic activities, three two - order sequences is composed of three depositional cycles and three regional unconformities ; secondly, under the control of structure activities such as fault - block activities and the influence of three - order climate cycles and source recharge, lower cretaceous can be divided into six three - order sequence ; thirdly, because fault activities is weak and fault slope is gently, fan deltas exist in steep slopes in early and later stages and subaqueous fans exist and turbidite fans exist in troughs in middle stage
主要的結論為：其一，受三期幕式活動影響，斷陷形成了3個大的沉積旋迴和3個區域不整合面，構成了下白堊統3個二級層序；其二，受斷陷內翹傾和塊斷等構造活動的控制，以及三級氣候旋迴和物源供給因素的影響，下白堊統劃分出6個三級層序；其三，在單斷斷陷湖盆中，湖泊階段的早、晚期由於凹陷邊界斷層活動較弱，斷面較緩，陡坡可以發育扇三角洲，在湖泊階段的中期主要為水下扇砂礫巖體，並在窪槽區發育濁積扇。Based on the dimensions, structures, shapes of the pores and the surface components of the porous minerals and rocks, this paper has summed up characteristics of typical porous minerals and rocks such as attapulgite, montmorillonite, sepiolite, zeolite and diatomite, and evaluated their application as filters, sorbents, ion exchangers and catalysts in environmental engineering
本文從微孔的尺度、結構、形態、成分等表面固體特徵出發，概括性地論述了凹凸棒石、海泡石、蒙脫石、沸石、矽藻土等十幾種多孔結構礦物（巖石）在環境修復工程中用作過濾材料、吸附劑、離子交換劑和催化劑等材料時的基本特徵和使用時應注意的問題。Among them, the improved initiative profile mode draw - out algorithm not only can precisely drawing out in the image the convexity object edge ; but also can approach the hollow place of the edge 。 at the same time, it introduced the auto - adapted changing size exterior restraint energy to increase the attraction scope, enables the control point not to
其中，改進主動輪廓模型的邊緣提取演算法不但能精確地提取圖像中的凸形物體的邊緣，而且能夠接近邊緣的凹陷處;同時，它引入了自適應改變大小的外部約束能量來增大吸引范圍，使控制點能夠不依賴于初始輪廓而快速地收斂到目標的真實輪廓。This article proposes in order to quickly hidden processing is carried on to multi concavo - convex polyhedron, the hierarchical structure is applied to carried on description on topo relations of three dimensional physique ; the bidirectional link table is applied to carried on the dynamic node assignment, for enhancing the efficiency of the algorithm ; when multi three - dimensional body is being hidden processing, the screen projection polygon should be carried on the overlaped eliminating confirmation and the polygon edges be carried on the computation of the intersectant points, the depth inspection, the comprehensive test and so on
摘要文章提出一種對多個凹凸形多面體進行消隱處理演算法，並介紹了採用層次結構進行三維形體的拓撲關系描述；採用雙向鏈表進行動態結點分配的演算法，提高了演算法效率；對多個三維物體消隱處理時，進行屏幕投影多邊形的重疊排除驗證，對多邊形邊進行交點計算，深度檢查，包容性測試等。During the resent years, bump mapping is one of the hotspot in reasearching the 3d graphics. it is used for rendering the details of geometric surface, which makes the geometric surface look bumpy and increases the fidelity of scene
凹凸紋理映射技術是三維圖形學中近年來研究的一個熱點，它被使用來繪制物體表面的細節，使物體表面看起來具有粗糙感，增加繪制場景的真實程度。At last, in the same system, by researching the shape restriction of concave region which self - occluding shadow information act on, and one simple modeling of concave region was fulfilled, which make it possible to model non - convex complicated shape in the passive vision system
最後，在同樣的成像系統下，研究了物體表面自遮擋陰影對凹陷區的形狀限制，得到了相關的約束條件，並由此實現了一種簡單的凹陷區域重構方法，使簡便的被動式視覺方法有可能重構非凸的復雜形體。Pressures under the margin of a deep cavity would similarly cause the underlying material to flow into it.
在一個深凹形體邊緣的壓力，同樣會導致邊緣部分物質的流入。分享友人
