摘　　要：利用荧光法生物气溶胶监测仪设备分别进行总粒子计数效率、荧光粒子计数效率评价,并在实验室和实际应用场景利用多种微生物气溶胶进行验证。通过菌落计数法和显微镜观察2种传统的离线检测方法与实时在线生物气溶胶监测仪的数值比对,发现实时生物气溶胶监测技术与传统方法检测结果具有较好的一致性。同时应用生物气溶胶监测仪对不同应用场景中的生物粒子进行监测,验证了检测结果的的可靠性。The total particle counting efficiency and fluorescence particle counting efficiency were evaluated by the fluorescence bioaerosol monitor,and verified by a variety of microbial aerosols in laboratory and practical application scenarios.By comparing the values of two traditional off-line detection methods,colony counting method and microscope observation method,it was found that the real-time bioaerosol monitoring technology has a good agreement with the traditional detection methods.At the same time,the bioaerosol monitor was used to monitor biological particles in different application scenarios,and the reliability of the detection results was verified.
