There have been a lot of studies this aspect when the exact solution u∈H~2 or u∈H~3. [4], [52] and [50]studied the convergence of conforming linear triangle elements with minimal regularity assumptions u∈H~4, here u is the solutions of the second order elliptic problems. However, their is another vital deficiency of the previous studies, i.e., they relies on the regularity assumption or quasi-uniform assumption on the subdivision of meshes.

对二阶问题，构造了一个新的单元格式，当其精确解具有低正则性时，在不要求网格满足正则假设或拟一致假设的条件下，我们得到了最优误差估计，与[33]相比，我们的证明方法较为简单；对于Stokes问题，研究五节点非协调矩形元对它的逼近，通过引入全新的估计方法，给出了关于速度、压力的超逼近性质。

Constrained by the triangle constraint integrated with the conventional epipolar geometric constraint, the local continuity constraint is enforced by changing the constraint areas dynamically according to the local texture density. 3 The topographic structure extraction and analysis based on grid DEMs are investigated in this dissertation, the topographic structure extraction approach fills depressions by adopting vector processes combined with traditional neighborhood raster processes, assigns flow direction over flat by applying a neighbor-grouping scan method.

2提出了一种基于核线影像对和良好匹配点三角形局部连续性约束和顺序约束下的影像匹配方法，该方法利用已知良好匹配点在Delaunay TIN的约束下进行纹理自适应的匹配传播，同时利用新的匹配点对Delaunay TIN进行动态细化使得局部几何约束区域的大小自动适应影像纹理特征的变化，从而得到更加可靠的影像匹配结果。

RESULTS: The microscopic observation showed chondrocytes in the transducted group proliferated stably, and triangle, and spindle cells were predominant in the seventh passage, accompanied by few long-spindle and root cells. In addition, the cells were of clear appearance and large lucency. However, in the non-transducted group, long-spindle cells were observed in the fourth passage, and almost all cells exhibited long-spindle shape in the fifth passage.

结果：①倒置显微镜观察，转导组兔关节软骨细胞生长增殖稳定，至第7代仍旧以三角形、梭形及纺锤形细胞为主，偶见长梭形和树根形细胞，且轮廓清晰，透亮度大，折光性强；而未转导组细胞培养至第4代时即己出现长梭形细胞，自第5代细胞形态几乎全部变成长梭形。

考虑到罗盘是报告中提交的第19飞行大队的失踪原因，海军指出，这个三角区是世界上两个罗盘既指向磁场北极又指向"真北方向"的地区之一。

Results:① The distance between handle of malleus and stapes head was(2.38±0.19)cm(2.00～2.70cm), the point selecting for measuring was outer margin of handle of malleus and stpes head.②The cross section form of one_third of the handle of malleus at the end, was triangle, the anteroposterior diameter of handle of malleus was(0.79±0.12)mm, the exterior and interior diameter was(0.58±0.10)mm at the crook point,the angle of line of manubrium mallei laid(83.24±8.33)°(66～98°)posteroinferior to arch of zygoma.③The long axis of prosthesis formed(27.60±1.75)°(24.6～30.2°)angle with the perpendicular of stapes.④The dependablity between the malleus_stapes distance and transverse diameter of tympanum, the location of umbo in tympanic membrane, the diameter of manubrium mallei, angle of line of manubrium mallei and arch of zygoma were not statistically significant.

结果：①锤_镫距离最短为(2.38±0.19)cm(2.00～2.70cm)，测量点为锤骨柄末端1/3处外缘和镫骨头；②锤骨柄末段1/3横断面形状接近三角形，弯曲处前、后方向直径为(0.79±0.12)mm，内、外方向直径为(0.58±0.10)mm；锤骨柄与颞线的成角为(83.24±8.33)°(66～98°)；③赝复物长轴与镫骨垂直方向成角平均为(27.60±1.75)°(24.6～30.2°)；④锤_镫距离与鼓室横径、鼓脐在鼓膜上的位置、锤骨柄直径、锤骨柄的方位的可能相关因素之间相关性检验无统计学意义。
