And then, a section of the involute was intercepted with the diameters of the point circle and the root circle, used it as the tooth face of the spline. The involute tooth thickness was drawn using the diameter of the divided circle and the tooth-form was drawn through rotating, mirroring image and cutting.

Two polar nuclei move to the micropylar end before sperm is released in a gap between the egg cell and central cell and subsequently taking off cytoplasm one after another. The sperm nucleus moving to the egg nucleus runs faster than the one to the polar nuclei. It fuses with the polar nuclei that are moving towards the antipodal cells at the chalazal end.

精子释放前，两极核移向卵细胞的合点端；两精子释放于卵细胞与中央细胞的间隙后，先后脱去细胞质，然后分别移向卵核和极核，移向卵核的精核快于移向极核的精核；精核与两极核在向反足细胞团方向移动的过程中完成雌雄核融合。

Two polar nuclei move to the micropylar end before sperm is released in a gap between the egg cell and central cell and subsequently taking off cytoplasm one after another. The sperm nucleus moving to the egg nucleus runs faster than the one to the polar nuclei. It fuses with the polar nuclei that are moving towards the antipodal cells at the chalazal end, Images showed the fusion process of male and female nuclei and polyspermous fertilization.

For example ,the non－ polar materials like hydrocarbons are heavy and draggy as compared to polar emollients,isoparaffins are light and smooth,the polar esters were significantly lighter and smoother,the branched chain and unsaturated esters were exceptionally light and smooth,in the case of straight chain esters,as the emollients become smoother and lighter ,the oiliness increases,in the case of unsaturated and branched chain esters,the emollient becomes lighter ,as well as less oily,when the alcohol chain length is decreased.

研究结果表明，物理化学特性明显影响润肤剂的轻柔感和油亮感，例如类似碳氢化合物的非极性物质相对于极性物质要粘稠些，异构烷烃则轻柔和光滑，带分支链的不饱和酯特别具有轻柔感和光滑感，带分支的不饱和酯相对直链饱和酯在油亮感方面有着特别的不同，直链酯随着产品光滑感和轻柔感的增加，油亮感也增加，对于带分支的不饱和酯而言，产品变得更轻柔，油亮感下降。
