Microstructure evolution including morphological change in the vicinity of the electrodes, porosity change and grain boundary migration was observed in polycrystalline CoO subject to electric fields at 1100 and 121$0^{\circ}C$ in air. At the cathode, the transported cations react with oxygen in the surrounding to form new lattices, while, at the anode, the reverse reaction occurs leading to lattice annihilation. Lattice formation also takes place at the surface of pores near the cathode inducing pore-filling effect. Grain boundary migration was found bo be enhanced or retarded depending on the field direction. It is therefore implied that the driving force of grain boundary migration is the vectorial sum of the curvature-induced chemical potential gradient and the electric field applied.

The objective of this study is to investigate the effect of submerged depth treatments on the evapotranspiration and yield of paddy rice, and to analyze the relation between evapotranspiration and the yield of paddy rice. Information obtained from this experiment will also provide basic information for future studies planned to estimate consumptive use of paddy rice. The rice varieties used in this experiment were Taeback (early mature variety), Iri 345 (middle mature variety), and Akibare (late mature variety). Five treatments for each variety and three replications for each treatment were carried out in this study. The results are summarized as follows; 1. The average evapotranspiration by submerged depth treatments during the whole growing period was 6.5mm/day for the plot changing submerged depth (O-4-6cm plot), 4.3mm/day for 2cm plot, 5.2mm/day for 4cm plot, 6.2mm/day for 6cm plot, and 6.2mm/day for 8cm plot, respectively. The maximum evapotranspiration was 6.5mm/day in 0-4-6cm plot and the minimum evapotranspiration was 4.3mm/day in 2cm plot. 2. The yield of paddy rice by submerged depth treatments was maximum in 0-4-6cm plot and minimum in 2cm plot, likewise the average evapotranspiration. The yield in 0-4-6cm plot was 39.4% larger than that in 2cm plot and higher as much as 9.5-19.4% compared with those in 4, 6, and 8cm plot. 3. The number of kernels per panicle, weight of 1000 kernels, and weight of rough rice showed a tendency to increase on the whole as the average evapotranspiration increased. 4. The results obtained from this experiment indicate that the irrigation method changing submerged depth by the growing season could be effective for increasing the yield of paddy rice.
