为老人承载记忆与生活的“海岛浮舟”

艺术与设计 2024年第9期 192-195页

作者：吉丽 line+(图) line+

“将一所废弃小学改造成一座托老所,是低生育率和人口老龄化背景下的一种功能置换策略。我们希望通过空间改造,为96位海岛留守老人塑造属于他们的精神家园,唤醒他们沉淀在时光中的温馨回忆。”line+联合创始人、主持建筑师孟凡浩说。

The open ratio of a current collector has a great impact on direct methanol fuel cell(DMFC)*** a number of studies have investigated the influence of the open ratio of DMFC current collectors,far too little attention has been given to how geometry(including the shape and feature size of the flow field)affects a current collector with an equal open *** this paper,perforated and parallel current collectors with an equal open ratio of 50%and different feature sizes are designed,and the corresponding experimental results are shown to explain the geometry effects on the output power of the *** results indicate that the optimal feature sizes are between 2 and 2.5 mm for both perforated and parallel flow field in the current collectors with an equal open ratio of 50%.This means that for passive methanol fuel cells,to achieve the highest output power,the optimal feature size of the flow field in both anode and cathode current collectors is between 2 and 2.5 mm under the operating mode of this *** effects of rib and channel position are also investigated,and the results indicate that the optimum pattern depends on the feature sizes of the flow field.
