空气中的离子状况及其对人体健康的影响程度已受到国内外学者的重视，空气中的离子带有正电荷或负电荷，在不同环境特征下其浓度以及正负离子两者间数量之比都存有差异。空气中的离子与烟尘等结合成为重离子，可作为空气质量评价的指标。为此，我们对福州和厦门两市几种典型的
The state of ions in the air and its impact on human health have been the focus of scholars at home and abroad, the air ions with a positive charge or negative charge, under different environmental characteristics of its concentration and the ratio between the number of positive and negative ions are There are differences. The ions in the air combined with smoke and dust into heavy ions can be used as an indicator of air quality evaluation. To this end, we have several typical Fuzhou and Xiamen cities
