As the complete characteristic curves of reversible pump turbine are often used to calculate the instantaneous parameters, this paper studies the characteristic curve and the wicket closure and opening law in pumped storage plants.Chapter 1 presents the importance and the necessity of this study and reviews the previous related research on hydraulic transient process and valve regulation in pumped storage plants.Chapter 2 analyzes the six collected characteristic curves of reversible pumped turbine and studies their diversification from the point of view of specific speed. The six collected discharge and moment curves with maximum efficiency have been fitted to piecewise continuous curves. This curve-fitting procedure is listed.Chapter 3 takes Liyang Pumped storage plant as an example and analyzes the effect of different characteristic curves on regulation guarantee parameters and the variety of its trochoid during the same operation status.Chapter 4 takes three pumped storage plants with different heads as examples and studies the characteristic of coordinated closure with wicket gate and ball valve and its effect on dynamic pressure in the spiral case, inlet pressure in the draft tube and the rise of rotating speed.Chapter 5 summarizes this paper and point out what should be done in the future research.

Methods A total of 60 patients with acute stroke of less than 24 h duration were included in the study. Nutrition risk screening was done in all those patients, with nutritional parameters to evaluate their nutritional status. Nutritional parameters were evaluated at admission and after 14, 28 d after the stroke, respectively. Results We found 15 cases with nutrition risk of 60 patients in admission, and incidence rate of undernutrition is 13.3%.

Under the base of it, also considering the characteristics of the multi-channel multistage rimfire gas switch, much study and experiments of the surface flashover along the PMMA insulator and the PMMA housing of the switch were done. Following conclusions were drawn: After introducing PMMA insulator among the board electrodes, the voltage of the discharging of the SF6 drops by 30%. With increasing of the pressure of SF6, voltage of the discharging descends more sharply. With PMMA spacer, the dispersing of the discharging voltage of the gas gap increased as compares to the unbridged gap, such increases in value of the discharging voltage become more obvious with the gas pressure increased.
