目的 掌握北京市顺义奥林匹克水上公园病媒生物分布及消长基本情况，为该区域病媒生物防治工作提供本底数据。

Based on the forenamed theory, Estimated the Total Electron Content including the second-order ionospheric error. Established the 2°×2° geomagnetic vector grid-model over mostly area of China , then processed some dual-frequency data to indicate the algorithm is feasible and correct. Obtained some useful conclusion after analyzing the result of data processing.

本文计算了基于中心电离层单层模型的覆盖中国区域的2°×2°地磁场格网点的矢量值，对计算结果的X、Y、Z三个方向分量进行二次曲面拟合，对两种考虑地磁场影响计算包含电离层延迟误差二阶项的TEC估计结果进行了计算，验证了拟合模型的正确性和可行性，并对试算结果进行了分析，得到了一些有益的结论。

Through merging the grids over the physically less important subregions and computing new topology skeleton of the vector field defined on this area, a physical feature preserving topological simplification is performed perfectly. Meanwhile, a remarkable data compression is implemented as well.

通过合并次要物理特征所在区域上的网格及在新网格布局下重新提取向量场拓扑，该算法不仅能完好地保持场内的重要特征，还能同时实现向量场的数据压缩。

The codeword of the initial codebook of the GLA algorithm trained by the PNN algorithm disperses in the whole input vector space,possesses the area with bigger input probability d...

仿真实验中，利用正态分布的随机数训练码书，恢复一段正态分布的随机数，采用Mahalanobis失真测度评价恢复数据的失真度。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
