查询词典 map-making

In this research,the ArcGIS is thought to perform data resampling before map algebra.IDL is used to realize the function of map algebra here.

研究认为ArcGIS进行地图代数计算效率比较低的主要原因在于它在计算时首先对数据进行重采样。

Using the map algebra function of the ARC/INFO system,a map of flood hazard assessment for Xiang River Basin is constructed by taking various natural factors,such as precipitation,topography and historic flood frequency,into consideration.

在综合考虑降雨量、地形以及历史上洪水灾害发生频次等自然因素的条件下，利用地图代数分析得到了湘江流域洪水灾害危险性评价图；在综合考虑人口密度、耕地面积百分比、人均GDP和单位面积水库和塘坝容量等社会经济指标的基础上，利用模糊综合评判法得到了湘江流域洪水灾害脆弱性评价图。

Then we in-vest gate Seiberg-Witten map, which defines the equivalence relation of the gauge symmetries in different spaces. We also analyse the U gauge electromagnetic field in noncommutative space. Finally we discuss the ambiguities of Seiberg-Witten map, and find although that some part of the ambiguities can be absorbed by gauge transformation and hence negligible, the existence of the matter field makes some other parts difficult to be absorbed by gauge transformation or field redefinition.

然后利用Seiberg-Witten映射，我们研究了不同空间的规范对称性的等价问题，并对非对易空间的电磁场进行了微扰分析，最后我们对Seiberg-Witten映射的松动进行了讨论，研究发现这些松动中的一部分可以由规范变换吸收因而是可以忽略的，由于物质场的存在，另外一部分很难用规范变换和场的重定义吸收。
