| 1. | Studies on air contamination caused by acarid mites 尿螨病的病原学研究 |
| 2. | With the help of grey incidence analysis , the indoor air contaminations which influence people most are found out with limited data 通过对室内空气污染物灰色关联度分析,在所知数据不多的条件下找到了对室内人员的舒适性有较大影响的几种室内空气污染物。 |
| 3. | In fact , it is not always the truth . because of bad ventilation and synthetic material , the concentrations of air contaminations indoors are even higher than that outdoors 由于不良通风和大量化学合成剂在建筑材料中的使用,使得室内空气污染物的浓度有时要高于室外。 |
| 4. | Because bad ventilation and a large amount of synthetic material used in the construction material , the concentration of air contaminations indoors are often higher than the outdoors 由于不良通风和大量化学合成剂在建筑材料中的使用,使得室内空气污染物的浓度常常高于室外。 |
| 5. | But the molecular mechanism of formaldehyde on evoked airway irritation is not clear . however , there are few of the hypotheses about it , for example , nielsen hypothesis , which explain how formal dehyde and other air contamination beget neurogenic inflammation . our task at present is testifying if the hypothesis is right or not 因此气道刺激作用的分子机理还有待阐明,不过有一些假设倒是引起了我们的注意,如nielsen假设就是一个比较重要的、正日益受到人们重视的理论假设,它从分子机理上解释了甲醛等空气污染物是如何通过辣椒素受体的介导引起气道刺激作用和气道神经源性炎症的。 |
| 6. | Indeterminacy exists in the influencing factors and indoor air quality itself . based on assessment of indoor air quality and its application , we analyze the inherent characteristics and rules of this grey system , which generally we are short of adequate information to describe , using grey system theory . firstly , we analyze the influence of indoor air contaminations on inhabitants " subject evaluation to indoor air , and calculate the degree of grey incidence between indoor contamination level and dissatisfaction rate at indoor air or ill symptom rate 针对室内空气品质问题本身及其影响因素存在的不确定性,本文围绕室内空气品质的评价及应用,运用灰色系统理论研究了这个“部分信息已知,部分信息未知”的“小样本” 、 “贫信息”不确定系统,通过对“部分”信息的生成、开发,实现对这一系统的正确把握和描述。 |
| 7. | The impact of unsteady aerodynamic wake of man ' s movement on contaminant transportation should be taken into account in the air contamination control of crucial medical rooms , and most previous studies regard the occupant as static object , which resulted in the contaminant distribution in hospital being rather different from the actual situation 摘要医院关键科室内应考虑人体活动引起的动态尾流对空气中污染物扩散的影响,通常假设人体静态的模拟方法并不能反映真实情况。 |
| 8. | The result showed that the contamination situation in the lower zone of the office , i . e . the zone of occupants , was affected by of that of supply air . the supply air contamination should be kept to a low level in order to provide a good indoor air quality . however , the variation of the supply pollutant concentration has no influence on the indoor contaminant distribution of such system 本文针对气态污染物,研究了不同送风浓度对系统的影响,结果表明:置换通风房间的下部区域受送风污染物浓度的影响较大,人的工作区恰好处于该区,实践中需要控制好送风浓度以保证人呼吸区的空气品质;但是送风浓度的变化并不影响置换通风下污染物的分层分布的特点。 |
