The following results were obtained: 1. Several multi-pore materials were compared and a nylon membrane was choosed to conduct experiments. 2. Two devices and methods for controlling negative hydraulic heads were developed. Coupled with the devices, a system for precise control of soil moisture udring pot experiment was developed. 3. Two times of pot experiment studying wheat seedling growth under precise soil moisture control were conducted. Some very important results were obtained. 4. Capillary rise, horizontal and vertical infiltration under different nagative hydraulic heads were observed. The concepts of "critical wetting distance" and "wetting coefficient" were proposed. The linear relationship between wetting front movement distance and cumulative infiltration amount was confirmed. Spatial distribution model of soil moisture and its simple derivation method were established.

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.
