This thesis focus on GPS application in magnetic suspension engineering:① the formulation of oblique cylindrical projection is worked out according to characteristics of long distance precise engineering and map projection theory. The author has developed an application to accomplish coordinate conversion from generally used coordinate systems to oblique Maglev Coordinates System.② considering not only project peculiarities but also position of control points, selection of initial points, connection type, selection of repeat baseline and ground observed quantities, GPS network is designed on electronic map and we may extract GPS network information by program developed using Visual Basic 6.0 while the results are stored in control point file and baseline vector file.③estimate accuracy of various GPS networks designed on electronic map by method of 2D restriction adjustment. GPS network simulation design and accuracy estimate come true.④Predominate the rules how connection type , repeat baseline and precise baseline of range finder influence GPS network precision through comparing accuracy of various GPS network. Thereby, the solution how to establish GPS network in long distance precise engineering is figured out.

Muzzle: Of medium length; that is, the distance from the tip of the nose to the stop is equal to the distance from the stop to the occiput.

鼻口部：中等长度；意思是，从鼻子的顶端到额段的距离等于从额段到后头部的距离。

The distance between Bombay and Calcutta, as the bird flies, is only from one thousand to eleven hundred miles; but the deflections of the road increase this distance by more than a third.

但是，全线实际的长度却至少增加了三分之一，这是由于铁路路线向北延伸要经过半岛北部的阿拉哈巴德的缘故。

After nest found, the dominating ecological factors with definite distance to nest tree (less than 10 meters) including tree species, tree height, habitat type of nesting-tree, nest position, the type of nesting tree branch, nest type, the type of nest-site, the viability status of tree and branch was described and measured. Geography coordinates (latitude-longitude) was converted into orthogonal coordinates, and add to Arcview3.2 as shape-file, and measured the distance between nest and the habitat type including double-line river, lake, seasonal lake, shallow mire, deep water mire, meadow mire, farmland, sparse forest, forest marsh, the boundary of Nature Reserve and road.

将调查所获得的东方白鹳巢址坐标转换成平面直角坐标，并将巢位点作为Arcview3.2中的矢量图层加入到已经矢量化的洪河保护区生境类型图中，运用Arcview3.2的距离量算功能，量算出每个巢距各生境类型的距离，包括双线河、湖泊、时令湖、轻沼泽、重沼泽、沼泽化草甸、旱田、疏林和森林沼泽，以及距保护区边界和公路的距离。
