Air quality — Stratified sampling method for assessment of ambient air quality 空气质素——环境空气质量评价的分层抽样方法
发布日期: 1989-09-21
这是通过估计百分位数和特征测量的频率分布来实现的。均值估计的应用仅限于某些情况。该程序可以在更长时间内计算与测量时间间隔内的实际气象条件无关的结果。
This is by estimating percentiles and means of the frequency distribution of measurements of characteristics. The application to the estimation of means is restricted to certain cases. The procedure enables results which are independent of the actual meteorological conditions prevailing during the interval of time of measurement to be calculated for a longer time.
