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.

The pilot study shows that the ammonia dissociation/synthesis reaction is inherently free of any potential side reaction problems, and also offers phase separation of products. The carrier of heat store is liquid. and is very interesting for long-term storage as it can be carried out at room temperature with no energy losses, Its theoretics energy storage density reachs 66.5kJ/mol, which outclasses sensible or latent heat storage. In comparison to other thermochemical energy storage, ATCES needs lower temperature in endothermic reaction(only 650℃), but It can produce over 550℃ high temperature stream in exothermic synthesiser. Furthermore, the heat store/recovery can change with adapt to the heat source/load automatically, and offers coninuous(24 h) production of heat, These advantages will see a rapid increase in the adoption of large-scale concentrating solar thermal power generation.

Research on Keeping Quality of Different Flesh Types of Prunus persica L.Niu Liang, Wang Zhiqiang, Liu Shu'e, Song YinhuaAbstract: Effects of post-harvest cold storage and Modified Atmosphere Package on fruit hardness, weight losing and soluble solid content of different peach or nectarine varieties were investigated. The results showed that:(1) There were obviously differences of fruit hardness among varieties of different flesh types. In room temperature, FH of '24-30' and 'Zhongtao No.2' went down slower than 'Zhongyoutao No.5' and 'Zhongyoutao No.10'. In cold storage, '24-30', FH of Zongyoutao No.5' and 'Zhongyoutao No.10' descent quickly after 2 weeks of storage while that of 'Shuguang' and 'Zhongtao No.2' quickly descent just after storage.(2) MA package could effectively slow down the decreasing of FH. There were obvious differences among different varieties while 'Zhongyoutao No.10' was less sensitive than others.(3) Soluble solid content went down after harvest and the procedure was slower in lower temperature. In room, MA package seems accelerate the descendent of SSC.
