摘要
泥鳅成熟卵受精孔外围的形态,在扫描电子显微镜的荧光屏上呈现完整的左涡旋状结构。本文通过把涡旋平面纹路与标准对数螺线比照,建立了涡旋平面纹路曲线的数学模型,再通过对卵膜孔周围流场的计算,揭示了这种鱼类受精作用的数学物理因素。
The surrounding modality of fertilization hole of mature eggs to misgurnus anguillicaudtus, takes on an appearance of complete left whirlpool-likestructures on the fluorescent screen of an electron scanning microscope. This paper constructs mathematical model of whirlpool-like plane curve in comparison between whirlpool-like plane curve and standard logari thmic spiral and furthermore bringhs to light the mathematics and physics factor of fertilized action to this fish, by means of calculating neighborhood fluid field to a hole in a membrane of the eggs.
