Analysing collected data, finds that chillness - tolerance of females is poorer than that of males, that the predicted effect of thermal sensation is not accurate by predicted mean vote ( pmv ) index, that evaluation on humidity sensation for males and females is almost the same except in a low - temperature environment where females are more sensitive to humidity than males, that draught sensation of females is more obvious than that of males, and that thermal comfort evaluation is affected by more environmental and psychologic factors besides thermal and humidity sensations
統計分析結果表明,女性的耐寒能力比男性差;
預期平均評價pmv指標對男女熱感覺的
預測效果較差;男女對濕感覺的評價無較大差異,只在溫度較低時,女性比男性覺得更潮濕;女性的
吹風感比男性強;熱舒適評價不僅受熱、濕感覺影響,還受其他環境因素及心理因素的影響。
The scheme of natural draining and pre - compression with stacking load has not only treated the dredging region, but also prepared a great deal of rocks for the second - stage construction of dayaowan and saved time for backfill work. and it will be possible that the berth 11 # of the second - stage construction is put into production as soon as possible. the scheme simplifies the unnecessary process of foundation treatment and its direct economic benefit and the social benefit are very remarkable
在隨后進行的大窯灣
吹填區兩個場地堆載處理的工程實踐中,借鑒了本次方案研究的成果,採用自然排水堆載
預壓方案,既進行了
吹填區的處理,也為大窯灣二期準備了大量的開山石料,節省了回填工期,從而使二期11泊位盡早投產成為可能;從經濟效益角度分析,採用此方案簡化了不必要的基礎處理過程,直接效益與社會效益非常顯著。
