空气污染习题求详解
图为某扩散试验场布置图,设置了13个采样点,间隔为4 °,试验进行了2次,实测浓度列在表中.
以y为横坐标,q为纵坐标,点出两次试验的横向风浓度分布图.
计算出这两次试验中,下风向100m处的σy值.
分别说明两次试验平均浓度的轴线在哪里?并由此判断当时的平均风向分别是多少度?哪一次近地层大气更不稳定?

otect our earth
how to protect our planet is our human beings' problem,including all counties and areas in
the world,because our earth is suffering more and more disasters.fisrt,our air has been
polluted due to factory,so we have to breath bad air that could harm our health.second,
people would like to cut trees to make money to live,which makes more worse to our air,
increases more carbon dioxide and causes more serious global warming.in some extent we
live a dangerous life in our planet,so we shold pay more attention to our earth,improve
our environment.
