| 1. | Visualization of air quality data based on circle segment technique
基于圆环段技术的空气污染物浓度数据可视化 |
| 2. | Air pollution load
空气污染物浓度 |
| 3. | The younger age group 0 - 14 years tended to have a higher risk for each 10g m3 increase in pollutants than those aged 15 - 65 years
同时，空气污染物浓度上升， 0至14岁组别的儿童因哮喘而入院的风险比15至65岁的哮喘患者为高。 |
| 4. | Based on the thinking of the pixel - oriented visualization technique , the circle segments technique was used to implement the visualization of the air pollutant data
摘要基于信息可视化方法中面向象素技术的基本思想，采用圆环段技术对空气污染物浓度数据实现了可视化。 |
| 5. | Longitudinal analytic equation is convenient for predicting and computing the concentration distributions of air pollutants in river - crossing roadway tunnels
摘要从纵向通风隧道内空气质量模式的解析解出发，纵向解析模式可方便地预测计算公路越江隧道内空气污染物浓度的分布。 |
| 6. | The proposed bridges also have the effect of reducing concentrations around main arterial roads in the north - eastern area of hong kong as cross - boundary road traffic is shifted to the west
由于拟建大桥令跨界道路交通西移，故可减少本港东北部主要干线道路的空气污染物浓度。 |
| 7. | The concentration of air pollutants at a particular place and at a particular time in hong kong is affected by many factors . these include emissions from sources at that particular place , other areas in hong kong and the mainland part of the pearl river delta ( prd ) region
在本港某一地点和时段的空气污染物浓度受许多因素影响，包括来自位于该地点、本港其他地点及内地珠江三角洲排放源的空气污染物排放量。 |
| 8. | The data collected at the station in 2003 show an upward trend of air pollutant concentrations similar to that recorded at the general air quality monitoring station in kwai chung , a district with land use ( an urban area with mixed residential , commercial and industrial developments ) similar to that in kwun tong . therefore , the upward trend of ambient air pollution is not a localised phenomenon peculiar to a particular district
（二）及（三）位于观塘区的空气监测站，属于一般空气监测站，其于2003年所收集得的数据，跟位于土地用途相若地区的葵涌监测站所录得的空气污染物浓度均有上升趋势，所以这不是一个局部地区现象。 |
