拓扑空间内非扩张型映射的不动点

本文分析了地下通风贮藏库的通风排热规律。从排热蓄冷角度出发,提出了评价和设计地下库的通风指标,并分析了库内的产热量大小与规律。在此基础上,给出了一套地下库通风系统的设计方法和步骤,并给出了部分计算结果。

Fixed Points of Nonexpansive Type Mappings in Topological Spaces

This paper analyses the relationship between the rate of ventilation and the amount of heat removed from the underground non-refrigerated fruit storage. In view of the necessities of removing the heat and storing the cold energy by soil around the storage, the index of ventilation for evaluating and designing the the underground storage is set up. Also the calculation of the amonnt of the heat generated inside the storage by fruits, workers and the lighting system is made and discussed. Based on that, the method and rogram for designing the ventilation system of the undergound fruit storage is given, and some results are finally shown.
