摘　　要：继1987年发现泥鳅成熟卵卵膜孔涡旋状结构之后,我们又发现了大银鱼(Protosalanx hyalocranius)卵膜孔呈现特异的沟脊放射状结构。本文进一步确证了又一种真骨鱼精子入卵除化学因素外,还存在着不容忽视的数学物理因素——机械动力作用,这两者相得益彰,形成了一个完整的精子引导系统。On the basis of finding the whirlpool-like structures of the mature eggs of Misgurnus anguillicaudatus. We advanced that durig the sperms of Misgurnus anguillicandatus entering mictopyle, there are still mathematical and physical dynamic factors besides the chemical explanation in 1990. Under the fact that the micropylar region of the mature eggs of Protosalaux bualocranis consists of some distict radiate grooves and ridfes, the article further confined another teleost sperm entering eggs still exist mathematical and physical dynamic factors and it coexists with the chemical factors, moreover, both sides bring out the best in each other, wgich form a complete sperm guidance system of micropyle.
