【摘要】 作者对乌鲁木齐市舞厅空气质量和微小气候的动态变化及其影响因素进行了研究。结果表明舞厅空气质量有一定变化规律:开场后空气中CO、CO₂、IP（可吸入尘）、细菌总数各项指标浓度逐渐上升,开场1h左右,所测各项指标与全场平均值相近,开场90min左右空气污染最为严重。经多因素分析,影响舞厅空气质量的主要因素为通风状况和人均容积。更多还原

【Abstract】 Dynamic change of climate and air quality in dance-hall and it’s influence factors were studied in 20 business dance-halls in Urumqi city. The results of study showed that after begining of a dance, the level of CO, CO₂, IP and total numbers of bacteria in air were gradually rising, and air pollution was the most severe when a dance had been proceeded for 90 minutes, at that time, the level of CO, CO₂ IP and bacteria went beyond the national health criteria. When a dance had been proceeded for 60 minutes, the level of indices above were similar to the means of that during all dances. The author suggested that the regular hygiene monitoring and supervising may be carry out at 60 minutes after a dance had begun, this would be effective and save time and labour. Analysis of multiple regression indicated that the main factors which might influence the air quality were indoor ventilation and volume per person in a dance-hall. Therefore, ventilation should be strenthened and the number of customers for a dance should be limited.更多还原
