Under a prior graded meshes , the quasi - optimal order error estimates in the - weighted h ^ 1 - norm uniformly are proved 在先验分层网格剖分基础上，在-加权h ^ 1 -模意义下得到了拟最优阶一致收敛的误差估计。
Visually , the design surface is a rectangular area with an overlay of grid dots that you can use to align report items on the layout 从外观上看，设计图面是一个覆盖了一层网格点的矩形区域，您可以使用这些网格点在布局中对报表项。
Suspendome is a new - type hybrid spacial structure system , and is put forward basing on the concept of combining tensegrity and cable dome with single - layer reticulate dome 弦支穹顶结构是将张拉整体、索穹顶等柔性结构的概念和单层网壳相结合而形成的一种新型的空间结构体系。
In order to deal with different kinds of building shapes , body - fitted quadrilateral grids are arranged in the inner domain and rectangle girds in the outer domain 为适应不同建筑体型的需要，本文提出在内层区域布置贴体的任意四边形网格，而在外围区域布置直角坐标矩形网格的分层网格离散模式。
As to the sting algorithm , the tune complexity of clustering is o ( n ) , but the time complexity of query is o ( g ) , where g is the number of grid cells at the lowest level and g is far smaller than n . 如sting算法，产生聚类的时间复杂度为o ( n ) ，但查询处理时间是o ( g ) ， g是最低层网格单元的数目，通常g远远小于n 。
Suspen - dome is a new self - equilibrium space structure , composed of single - layer lattice shell and cable - strut tensile structure . for its novel and beautiful shape , it has a widely practical perspective 弦支穹顶结构是由上部的单层网壳结构和下部的张拉索杆体系组合而形成的新型自平衡体系，由于其造型新颖、美观，具有非常广阔的工程应用前景。
Its biquadratic finite element approximation is considered and under the appropriately graded meshes , quasi - optimal order error estimates in the - weighted h ^ 1 - norm , up to a logarithmic factor in the singular perturbation parameter , are proved 然后，考虑此方程在分层网格剖分上的双二次有限元逼近，在-加权h ^ 1 -模意义下得到了至多相差一个关于摄动参数对数因子的拟最优阶收敛的误差估计。
In this thesis , a new method named local analysis method was presented which the whole structure is divided into two parts : the upper structure and the lower structure . the problem distribution of initial pre - stress of suspen - dome can solved by this method 提出了基于将上部单层网壳和下部索杆体系两部分结构分块的新的分析方法?局部分析法，可以解决弦支穹顶结构的初始预应力分布的确定问题。
The static behavior under vertical loads of kiewitt ' s suspen - dome was analyzed on the initial state . moreover , the behavior of suspen - dome and single - layer lattice shell are compared . the influence of kinds of parameters is studied 本文对初始态下的kiewitt型弦支穹顶结构在竖向荷载作用下的静力特性进行了深入分析，并同单层网壳结构静力特性进行比较；为了掌握各个参数对静力特性的影响程度，进行了参数分析。
