人需要呼吸空气以维持生命，被污染了的空气对人体健康有直接的影响。大气污染物对植物造成危害，尤其是二氧化硫、氟化物等对植物的危害是十分严重的。使植物叶表面产生伤斑，或者直接使叶枯萎脱落；或者对植物产生慢性危害，造成植物产量下降，品质变坏。对天气和气候都会产生严重的不良影响。
石油炼化/化工厂的过程控制和排放监测具有很大的挑战性，比如腐蚀性气体、高粉尘负荷和高温，这样的环境下，使用萃取的系统需要的维护量是很大的。世驰科技提供的解决方案是采用非接触式差分吸收光谱法（DOAS）或红外光谱法，使用一条光路贯穿整个管道。光束通过光纤传输到分析仪，而这个分析仪又同时监测几个路径。
Background of the Proposal
Humans require air to sustain life, and polluted air has a direct impact on human health. Air pollutants pose a threat to plants, particularly sulfur dioxide and fluoride, which can cause severe damage to plants. They can lead to the formation of lesions on the surface of plant leaves, or directly cause leaves to wilt and fall off. Alternatively, they can cause chronic harm to plants, resulting in decreased plant yield and deteriorated quality. Moreover, they have serious adverse effects on weather and climate.
Process control and emission monitoring in petroleum refineries/chemical plants pose significant challenges, such as corrosive gases, high dust loads, and high temperatures. In such environments, the maintenance required for extraction systems is substantial. The solution provided by Shichi Technology is to adopt non-contact differential optical absorption spectroscopy (DOAS) or infrared spectroscopy, utilizing a single optical path throughout the entire pipeline. The light beam is transmitted through optical fibers to the analyzer, which simultaneously monitors multiple paths.
