效率

A first reaction to these developments might be that they are favorable, as alongstanding tenet of state and local public finance has been that on efficiency grounds it ispreferable to assess subnational taxes using jurisdictions that encompass greater areas andlarger populations (e.g., state rather than local), as the interjurisdictional mobility of taxbases is significantly lower for such jurisdictions than for smaller entities; as a result,efficiency costs from suboptimal location decisions will be reduced, more progressivity in thetax structure may be introduced if deemed desirable, and economies of scale in revenuecollection may be realized.

第1个反应是，这些事态发展可能是有利地，他们作为一个，长期宗旨，国家和地方公共财政一直认为这是提高效率的理由宜评估使用更大的司法管辖区，包括地区和地方税较大的人群，由于流动性税收interjurisdictional基地，显着高于小实体，如司法管辖区为低；因此，从最理想的位置决定的效率成本将降低，在较累进税务结构，可由假如认为可取的，规模经济的收入收集可能得以实现。

A first order quasi phase matched periodically poled LiNbO 3 for SHG with 6.5 μm period, 12 mm length, 10 mm width and 0.5 mm thickness has been successfully fabricated by applying an external electric field at room temperature from an high pulsed voltage generator. About 18 mW of CW 0.532 μm green light was obtained pumped by an 1.1 W of CW 1.064 μm Nd∶YAG laser with end coupling, which corresponds to 1.6% power conversion efficiency.

Then the spatial index is constructed which includes not only the external approximate expression but also interior approximate expression of spatial object and is extended from tranditional index only with external approximate expression. The index structures of MR-tree and MRD-tree based on multi-approximate expression are set up with the prototype index of R-tree, and the relevant algorithms about the index of insertion, deletion and search are provided. Then, the efficiencies of constructing index based on the multi-approximate expression and window range query are analysised and compared. In addition, the several algorithms and efficiency of soving the maximum enclosed circle and maximum enclosed rectangle are discussed and analyzed during constructing index based on multi-approximate expression.

首先，论文讨论了空间数据的特点、空间数据库的关键技术以及空间对象间的拓扑、距离以及方向关系，分析了空间对象的外部和内部近似表达，然后将传统索引中只利用空间对象的外部近似扩展为既有空间对象的外部近似又有空间对象的内部近似，即以空间对象的多重近似来构建索引，并以R-tree为索引原型构建基于多重近似的MR-tree和MRD-tree索引结构，然后给出了相关索引的插入、删除及查找算法，并通过实验比较分析了基于多重近似索引与基于外部近似索引的构建效率及窗口范围查询效率。
