| Abstract: | In order to achieve measuring the particle size distribution,particle concentration and mass concentration of smoke simultaneously,the acceptable test of standard-device for smoke concentration was developed.The measurement combined the laser forward scattering theory and extinction theory.Using the test data,the mean values of smoke particle concentration and mass concentration at a certain time were calculated.The results showed that the acceptable test of standard-device for smoke concentration was natural.The values of particle size and particle size distribution of smoke were exact. |
