Introduce a cell split method to manage the complicated terrian , and produce the terrian database by C + + Builder .

提出用分块处理的方法，对复杂的地形地物进行处理，并用C++Builder建立了地形地物数据库。

Many people have used meso-scale numerical models to research the influence of terrian in south china and gotten many significative conclusion , but the research of Shandong central terrain 's influence is quite few .

在我国，人们利用数值模式对华南山区的地形影响研究较多，得出了许多有意义的结论，但对于华北地区的鲁中山区地形影响的研究却很匮乏。

Also we need these attack helicopters for the terrian up north I cant stand the Cobras they are pre-historic just like our F16s .

而且我们的北方领域也需要这样的攻击直升机，我受不了“眼镜蛇”，它们就像我们的F16一样都太老旧了。

Combine the restriction of human eye vision , the terrian of sensitive area is displayed with high-resolution data and the terrian of no sensitive area is displayed with low-resolution data .

结合人眼视觉的限制，对敏感地区的地表用高分辨率数据显示，对不敏感地区的地表则用低分辨率数据显示。

For the rough relief terrian , it is difficult to delineate them by only one function . Large outer correction errors would be brought in if only the plane function or spherical function was used .

对于起伏不平的地形，确难用一个函数描述它们，若仅用平面或球面函数等来表达，势必产生较大的、且又难以满足精度的重力外部校正误差。

Terrian features are very important in drainage basin analysis , hydrological analysis and the progress of mineral exploration and evaluation . The spatial distribution characteristic of terrain attributes is an important indicator which used to describe space process changes .

地形因素是影响流域地貌、水文、矿产勘查与评价等过程的重要因子，地形属性的空间分布特征是人们用于描述这些空间过程变化的重要指标。

Moving and stationary target acquisition and recognition ( MSTAR ) program has shown that segment synthetic aperture radar ( SAR ) imagery into taeget , shadow and background clutter regions is a efficient measure in the process of recognition targets in open terrian .

运动、静止目标获取与识别（MSTAR）计划表明，将合成孔径雷达（SAR）图象分割成目标、阴影和背景杂波区域对于从开放环境中进行目标识别是一种有效的手段。
