研究了制粉工艺参数对粉末粒度、粒度分布以及粒度分布类型的影响，并对粉末粒度进行了理论计算。
Effects of processing parameters on the particle size and its size distribution were studied. Particle size was also calculated.
沉积物类型极大地影响着放射虫的分布，放射虫的丰度和分异度明显地随粒度的增大和陆源物质含量的增加而减小。
The distribution pattern is also strongly affected by the sediment type, and radiolarian abundance and diversity decrease with the increase of grain size and terrigenous material input.
