Firstly, a spherical mesh with regular subdivision connectivity is constructed to partition the spherical domain into some small regions. Then the region, which contains the query point p, is found according to the position of p and selected as the search area for locating p. During the point location, the barycentric coordinates are used to extract local heuristic information about the location of p so as to find the shortest path from the start triangle to the target one containing p.

通过构造规则子分网格将原始球面网格区域划分成若干具有子分层次关系的查询小块；在进行查询前，根据查询点p的位置找到它所在的小块作为搜索区域，从而极大地缩小了查询范围；在查询过程中，根据重心坐标所包含的启发信息，选择一条从初始搜索三角形到目标三角形的最短查询路径。

The night elves' buildings, all crafted from wood, interested me because each building seemed to be crafted from a single tree or piece of lumber — none of the typical signs of craftsmanship such as nails or screws hold the pieces of wood together.

暗夜精灵的建筑全是木制工艺，使我很感兴趣，因为每个建筑似乎是由一整棵树或一整块木材制成，没有那种典型的木工的标志——比如用钉子或螺丝把几块木材接合到一起。

Based on the study, the recognition characteristics of AE selfsimilarity is provided at critical fracturing of concrete under three point bending experiments.

并在此基础上，根据混凝土试块的三点弯曲试验，确定出了混凝土试块断裂的声发射自相似性识别特征。

Because the derivation of the extended system has a block lower triangular form, the method of splitting iteration is applied to compute simple bifurcation point, not only computational work is reduced, but also local quadratic convergence is achieved.

由于所构造的扩充系统的导数具有分块下三角形式，采用分块迭代的方法进行数值求解，不仅减少了计算量，而且是二次收敛的，从而为Navier-Stokes方程非退化简单分歧点的数值逼近提供了有效的算法。

The result of attrition is that, where the areas of the whole leaves follow a normal distribution, a bimodal distribution is produced, one peak composed mainly of fragmented pieces, the other of the larger remains.
