Terrain correction is needed when we do research on the internal structure of the Earth, the Lunar, and Mars by use of satellite gravity measurements, then calculate global Bouguer gravity anomalies. It is effective to carry out terrain correction in spherical coordinates.

利用卫星重力测量资料研究地球、月球与火星等星体的内部构造时，需要进行重力地形校正，计算全球布格重力异常，而在球坐标中实现地形校正计算是一种有效的途径。

Then, a continuous soil horizon thickness distribution map was drawn with the aid of ARC/info software based on samples collected at the area with high value of fuzzy membership and population of the similarity model using the linear and additive weighting function.

通过对研究区地形因子的模糊聚类，提取了地形因子组合与特定土壤属性的定量隶属度关系，然后对隶属度高值区土壤进行目的性采样为隶属度函数赋值，制作研究区土层厚度连续分布图。

More emphasis is given to study the rule of data blocking and common method of building tile-pyramid model and linear quadtree tile-index. On the other hand, this thesis also investigates such problems as target-tile searching, tile-request prediction and edge matching of block terrain drawing.

着重分析了地形数据的分块规，构建瓦片金字塔模型和线性四叉树瓦片索引的一般方法，对目标瓦片搜索、瓦片请求预测及分块地形绘制接边等问题进行了探索性研究。

Digital Elevation Model is a digital description of land surface, which can provide new means and perspective on study of geomorphology.

数字高程模型正是对地球表面地形地貌的数字表达和模拟，这就为研究地形地貌提供了新的思路和方法。

A 4 Quantity Model (4QM) for partitioned area entities in terrain OTIN via combining topology relation with metric relation is proposed subsequently. Spatial topological relation and metric relation are described in one model.

将拓扑和度量关系相结合，本文给出了地形OTIN中剖分面状地理实体的4数模型(4QM)，使得拓扑关系和度量关系表达在同一个模型中。4QM可以作为地形OTIN中地理实体边界简化的参考。

Starting from a barotropic model equations including large-scale orography,friction and heat factor,by means of scale analysis and small parameter method,then a barotropic quasi-geostrophic model with large-scale orography,friction and heating is obtained.

从包含大地形、摩擦及加热作用的正压模式方程组出发，通过尺度分析、小参数展开和线性化等方法，导出一个含大地形、摩擦及加热作用的准地转正压模式。

In summer the continent is the heating source and the ocean is the heating sink relatively in summer due to the land-sea thermal differences, so the increased topography essentially intensifies the continental characteristics of the underlying surface. The orography uplift enhances the effects of the heating source on the atmosphere and increases pricipitation in the Plateau region.

由于海陆热力差异，夏季大陆是热源，海洋则是相对冷源，地形升高实质上是增强了下垫面的大陆性特征，使下垫面对大气的加热作用(潜热加热的贡献占据第一位)随着地形升高而加强。

The trough is mainly confined by the continental slope to the north and by sloper off the Ryukyu volcanic islands.

东海海水与黑潮水在东海大陆棚坡区交换，而此地区的地形为不规则状，这种地形效应値得进一步探讨其对黑潮边缘交换过程的影响。

Landforms of topography, vegetation and climate are in fluential factors in formation of soils

地形或地形学、植被和气候都是对土壤形成有影响的因素。

The imbedded water level is affected by landform, vegetation and water level, and because there is no orderliness of the change of every point in the peatland, there is no orderliness of the change of the immbedded water level in the peatland.

水位埋深受地形、植被和水位等因素的综合影响，由于地形变化并没有一致性，因而水位埋深变化并没有一致性。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
