物理学家通过对精子游动方式的研究发现,当精子周围的液体变得具有“粘弹性”时,它们会集结成紧密的群体。粘弹性的液体不仅粘稠,而且具有弹性和延展性,在受到扰动的时候会弹回原先状态。科学家观察了牛精子在不同液体中的游动情况,发现正是这种粘弹性使精子聚集成群。如果周围液体粘稠而不具有
By studying the way sperm travel, physicists have found that when the liquid around a sperm becomes “viscoelastic,” they build up into tight groups. The viscoelastic liquid is not only viscous, but also elastic and ductile, which will spring back to its original state when disturbed. Scientists have observed the sperm motility in different fluids and found that it is this viscoelasticity that groups sperm agglomeration. If the surrounding liquid is not viscous
