The average relative parameters of plotting were 0.952 for micrometer and 0.985 for Coulter counter, respectively. Each kind of micro-phytoplankton had its characteristic distribution curve and mean BSD.

• 在确定浮游植物粒径分布形态的基础上，利用Gauss函数描述浮游植物的分布形态从而进一步确定浮游植物在统计学意义上的中值粒径，这比以往研究中仅用简单的加权平均求得浮游植物的平均粒径于理论上更加合理。
