摘　　要：空气真菌是一种重要的空气污染因子.建筑材料表面真菌孢子的释放和气溶胶的形成,是研究室内空气微生物气溶胶暴露及其对人体危害的关键因素.采用自行开发的平行气流真菌孢子释放强度测定装置(PAFST),对空气中常见的4种真菌柑桔青霉、扩张青霉、黑曲霉和枝孢霉,3种材料表面,5种风速下的释放强度进行测试.结果表明,相同材料和风速条件下,青霉属较枝孢属更容易释放出孢子.经t检验,在无纺布和超细玻璃纤维表面真菌孢子的释放强度大于在琼脂表面的释放强度.真菌孢子释放强度与气流速度的函数关系可以统一表示成y=a.xb的幂函数形式.The release and aerosolization of the fungal spore on the surface of architecture material are the key factors to result in the bioaerosol exposure and do harm to human health and lives. The self-developed parallel air-flow fungal spore source strength tester （PASVF） was used to test the release strength of 4 common fungi, Pencillium citrinum, Penicillium expansum, Aspergillus niger and Cladosporium Spp on the surface of 3 materials at the wind velocity of 5. The results show that it is easier for Penicillium to release spore under the same condition. By t test, the fungal spore release strength for bag filter and ultra-fine fibreglass is higher than that for agar. The relationship of fungal spore release strength with airflow velocity can be expressed as a power function.
