沉降法测定大气真菌粒子含量公式的检验

Test for Gravity Precipitation Method of Measuring Atmospheric Fungous Particle Load

在沈阳市对作者提出的由大气真菌粒子的沉降量计算大气真菌粒子含量的公式进行了检验。结果表明，在沈阳市由作者公式计算的大气真菌粒子含量为１８２４个／ｍ￣３，Ａ·Ｓ采样器测定的大气真菌粒子含量为１８０７个／ｍ￣３ ，二者之间的比值为１．０，ｔ＝０．０９８，Ｐ＞０．５０，两种方法得出的大气真菌粒子的含量非常相近。经验证，本公式是一个准确、简便的计算大气真菌粒子含量的公式。

The test was conducted to testify the validation of our earlier proposed equation of measuring atmospheric fungous particle load with gravity precipitation method in Shenyang city. The result showed that the atmospheric fungous particle concentration estimated by our equation(1824 count/m3)was not statistically different from the concentration measured by Andersen viable air sampler(1807 count/m3,t=0,098,p>0. 50).The ratio of the two concentrations was 1.0.The test study indicated that our equation is an easy,accurate equation for estimating atmospheric fungous particle load.
