摘　　要：尝试在常温下使用微波辐射减少卷烟烟气中亚硝胺的含量.鉴于微波对于亚硝胺的分解作用,报道了去除卷烟中亚硝胺的新途径:使用微波直接辐射成品卷烟.研究发现经1 kW的微波辐射90 s,烟草中大约有25%～30%的亚硝胺被降解而主流烟气中的亚硝胺去除率达到50%～60%.Microwave irradiation was tried to reduce the nitrosamines level of tobacco smoke under the mild condition. According to the microwave-induced degradation of nitrosamine,we try an innovative and practical way to reduce the nitrosamines content in tobacco by directly irradiating the cigarette sealed in packaging case. Through irradiation of the cigarette sealed in packaging case with the microwave of 1 kW for 90 s,25%～30% of nitrosamines in tobacco while 50%～60% in mainstream smoke of the cigarette are reduced.
