查询词典 leading edge

Based on joint several edge detection methods, the edge was detected from SAR image by using Haralick algorithm and general fuzzy operator algorithm, and then the detected edge was subtracted from SAR image, then Lee filter was used to filter the speckle image without edge, at last the edge was added to the filtered image.

常规滤波算法在滤除噪声的同时也带来了图像边缘模糊问题，利用多种检测图像边缘算法的有机组合，首先提取出图像边缘，然后将边缘从图像中剔除，对剩下的无边缘噪声图像用改进Lee滤波法进行噪声抑制，再把边缘图像加入，最后得到了能保持边缘的SAR图像相干斑滤除图像。

In the region upstream of vortex breakdown, the sectional streamlines emanating from the leading edge spiral inward to primary vortex and in the region downstream of the breakdown, on the other hand, the streamlines separating from the leading edge are not entrained into the vortex core in the instantaneous sense. Along the axis, the topology of the primary vortex alters several times starting from stable focus near the apex to unstable focus, and lasts back to stable focus near wake edge, the stable hmit cycle and unstable limit cycle are shown in this evolution.

发现在截面流线谱中，即使奇点的类型、数目及位置相同，奇点的连接方式也有可能不同；旋涡破裂点前，主涡由来自前缘的力线卷绕而成，主涡焦点与前缘半鞍点相连，旋涡破裂后，来自前缘的力线不再卷入主涡，主涡焦点与对称面上的鞍点相连：在流体由翼尖流向后缘的过程中，截面流线谱的拓扑结构发生了多次变化，主涡焦点相继由稳定状态转变为不稳定状态，最后又转化为稳定状态，并先后出现了稳定的极限环及不稳定极限环。

Through the tests on gas driving water and water driving gas, the flow law of gas and water was real-time observed. Mainly based on the test of water driving gas as an example, the development of molding coal sample and NMR triaxial osmoscope was demonstrated. The experiment process of water driving gas and parameters were demonstrated. NMRI images of molding sample in horizontal cross-section along the driving direction were obtained by NMRI instrument. The results from images were analyzed and compared. Some novel laws were obtained as the following:(1) the leading edge of water driving has inconsistency. This certified the important previous conclusion that the storage of methane mainly was absorbed in inner surface of pore from NMRI technique;(2) the existence of dominant driving pathway was tested and the way kept almost fixed. The pathway is apt to exist in the edge of coal samples where pore and fracture fully develop;(3) the variation of water flow determines the transport velocity of leading edge of water driving and it has lag effect;(4) the effectiveness of the first driving is better than the second driving;and (5) the subsequence of water driving gas are from trunk fractures to branch fractures, then to branch pores.

主要以水驱气NMRI试验为例，详细介绍了核磁共振三轴渗透仪和型煤试件的研制，并重点阐述了水驱气试验过程和相关参数，利用NMRI技术实时观测得到了不同时间沿驱替方向型煤试件水平剖面的NMRI成像图，最后对试验结果进行了比较分析，揭示了一些新的规律认识：(1)水驱替前缘具有不一致性，从NMRI试验角度验证了前人甲烷类气体赋存形式主要以吸附在孔隙内表面为主的重要结论；(2)煤试件存在优势驱替路径，且这种优势路径在驱替过程中基本保持不变，水驱气的优势驱替路径易产生在煤试件边缘，即煤孔隙裂隙发育区；(3)水驱流量变化决定了水驱前缘的运移速度，且对水驱气效果具有滞后效应；(4)水驱气初次驱替效果好于二次驱替效果；(5)水驱替气的顺序为：主要大裂隙—周边裂隙—周边孔隙。
