The research aim of this thesis is the winding end insulating structure of oil immersed power transformer 110kV . Beause of the very asymmetric electric field, the higher electric field would apeared in the oil-gap and partial charge will easily engendered in the wedge oil-gap between static ring and head block of winding end.The two-dimensional isoparametric and finite element method is used for analyzing and calculating the electric field distribution in high voltage winding end insulating structure.

A seven-node difference scheme of the diffusion equation was proposed to study the behaviors of transient electromagnetic field in complicated 3-D geoelectric body. Models of roadway and anomaly body were set up for simulating the transient field excited by a vertical magnetic dipole source. The result of numerical simulation shows that the presence of low resistive conductor leads to noticeable distortion of isolines for the "smoke ring" field, whereas the distortion is not so obvious where the roadway and the poor conductor are located.

To study the effect of papermaking wastewater irrigation on soil hydrological properties in saline reed field, different wastewater irrigation frequencies were employed in the saline reed field of Yellow River Delta. Soil infiltration course and hydrological properties were determined in field and laboratory. After wastewater irrigation, the change of the soil pH value, soil salt content and soil hydrologic-physical properties were observed. The results were showed that: 1 After wastewater irrigation, the mean reduction of soil pH value was 6.0%.
