1·Based on the box model used in atmospheric Science, Calculation of indoor air pollution concentration had been developed and it's effect factors were discussed as well.

在借鉴大气总量控制箱模式的理论基础上，探讨了室内空气污染物浓度的新的计算方法，并通过此模式对影响因素作了分析和分情况解释。

2·Authorities measure the concentration of particulates with a diameter of less than 10 microns - so-called PM10 - in the air to determine pollution levels.

检测机构会检测直径小于10微米的微粒，即PM 10浓度，并由此判定污染程度。

3·Objective to study distribution of air pollution source, determine the historical exposure concentration of air pollution in the region, and assure the work scope of health investigation.

目的根据区域大气污染源分布研究确定区域大气污染物历史暴露浓度，确定健康调查工作范围。

4·Through analysis of concentration change with time and space of mian air pollutants, some causes of the change regularity are expounded, being useful for pollution forecasting and control.

通过分析大气中主要污染物浓度的时空变化，阐明形成此规律的原因，对大气污染物的预测和防治具有一定意义。

5·If the brood indoor and ventilated bad, oxygen will gradually reduce the concentration of carbon dioxide, air pollution, increase become up.

如果育雏室内通风不良，氧气就会逐渐减少，二氧化碳浓度增大，使空气变得污浊起来。

6·Results: The main channel of atmospheric pollution and the law governing the changes in concentration were summed up and a proposal for the control of air quality in the compartments was advanced.

结果：分析归纳了舱室大气污染的主要途径及浓度变化规律；提出了舱室大气质量控制建议。

7·Objective: to further study concentration-response relationship between daily mortality and particulate air pollution, to provide scientific basis for making policy.

目的：研究颗粒物空气污染与居民每日死亡率暴露-反应关系，为环境决策提供科学依据。

8·Air pollution prediction is a direct problem, and deriving diffusion coefficients from the concentration of pollutants is an inverse problem.

空气污染预报属于正问题，而从污染物浓度来求解扩散系数则属于反问题。

9·Pick to PM2.5 it can be suspended in the air for a long time, the higher its concentration in the air content, means, the more serious air pollution.

摘要PM2.5它能较长时间悬浮于空气中，其在空气中含量浓度越高，就代表空气污染越严重。

10·Monitoring of particulate matter concentration is the basis for urban air quality evaluation and pollution control, and also very important for health effects assessment.

颗粒物浓度监测不仅是评价城市空气质量的基础，而且是进行城市污染控制与环境健康效应评估的重要依据。
