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.

On one hand, the integration between literary autonomy and social heteronomy is the abscissa of the coordinate axis. On the other hand, the integration of ancient and present poetic resources, and Chinese and western poetic resources is the ordinate of the coordinate axis. Integration in Wu Mi\'s poetic thoughts is embodied in two aspects: Firstly, it means the integration of ancient and present poetic resources, and Chinese and western poetic resources. Wu Mi maintains that various poetic resources should be treated equally so as to find the similarities and differences among them. Only with a broad cultural view and calm attitude toward various poetics resources can a new system of modern poetics be achieved.
