4) Ion polarity ratio
单极系数
1.
The results showed that negative air ion concentrations increased gradually and ion polarity ratio decreased gradually from city center to suburb.
结果表明,从市中心向郊区空气负离子浓度逐渐增大,单极系数逐渐减小;有林地区空气负离子浓度明显高于无林地区,针叶林地区全年平均空气负离子浓度高于阔叶林地区,但春、夏季节则阔叶林地区高于针叶林地区;有瀑布和溪流等动态水的地方空气负离子浓度明显增加;室内空气负离子浓度低于室外,但绿色植物可使室内空气负离子浓度增加;一天中白天空气负离子平均浓度高于夜间,一年中夏季最高、冬季最
2.
