There is much inconvenience in measuring particle size distribution by experiments at present, because of droplets movement complexity in spray drying.
由于喷雾干燥中雾滴的运动较复杂，所以目前多是通过实验测量来确定雾滴粒度分布，有很多不便因素。
Two preparation methods are compared and confirm that the spray pyrolysis may have an average spread of the particle size distribution, which will lead to the effective absorption of the sample.
对于固相合成和喷雾热解法两种方法制备出的样品进行了比较，确定了喷雾热解的制备方法可以使得组分混合的均匀从而导致样品对激发光有更加充分的吸收。
