在現代城市中，空氣品質成為人們關注的重要議題之一。為了改善城市居民的生活品質，許多城市開始專門營造清新空氣的智慧城市。透過先進的環境感測技術，城市可以即時監測空氣品質，並採取相應的措施來改善空氣質量。智慧城市中的空氣淨化器也起到了重要作用，能夠過濾空氣中的有害物質，讓居民呼吸到更清新的空氣。
同時，大數據分析也成為智慧城市建設中不可或缺的一環。通過收集和分析大量的數據，城市管理者可以更好地了解空氣污染的來源和分佈情況，從而采取更有效的措施來改善空氣品質。智慧城市的建設不僅可以提升居民的生活品質，還可以為城市的可持續發展做出貢獻。

Title: Creating a Smart City with Fresh Air
Article: In modern cities, air quality has become one of the important issues that people are concerned about. In order to improve the quality of life for urban residents, many cities have started to create smart cities that specialize in creating fresh air. Through advanced environmental sensing technology, cities can monitor air quality in real-time and take corresponding measures to improve air quality. Air purifiers in smart cities also play an important role in filtering out harmful substances in the air, allowing residents to breathe in fresher air.
At the same time, big data analysis has become an indispensable part of smart city construction. By collecting and analyzing a large amount of data, city managers can better understand the sources and distribution of air pollution, and take more effective measures to improve air quality. The construction of smart cities can not only improve the quality of life for residents but also contribute to the sustainable development of cities.
