This paper studied the impacts of different dose ultraviolet irradiation (254 nm, UVC) on the sperm motility and longevity of Acipenser baerii. Ultraviolet irradiation had significant impacts on the sperm motility, its fast motion time, and longevity. With the increasing dose of ultraviolet irradiation, the sperm motility decreased rapidly first, increased rapidly then, and decreased rapidly again. The sperm fast motion time had the similar variation trend as the sperm motility, but the sperm longevity kept decreasing with increasing dose of ultraviolet irradiation. When the ultraviolet irradiation dose increased to 288 mJ x cm(-2), the sperm fast motion disappeared; when the ultraviolet irradiation dose increased up to 324 mJ x cm(-2), the sperm had no motility and died. According to the "Hertwig effect", the optimum ultraviolet irradiation dose for inactivating A. baerii sperm was 216 mJ x cm(-2).
本文研究了不同剂量紫外线照射（254nm，UVC）对史氏鲟精子活力和寿命的影响。紫外线照射对精子活力、快速运动时间和寿命有显著影响。随着紫外线照射剂量的增加，精子活力先迅速下降，然后迅速上升，随后又迅速下降。精子快速运动时间与精子活力具有相似的变化趋势，但精子寿命随着紫外线照射剂量的增加而持续下降。当紫外线照射剂量增加到288mJ·cm⁻²时，精子快速运动消失；当紫外线照射剂量增加到324mJ·cm⁻²时，精子失去活力并死亡。根据“赫特维希效应”，灭活史氏鲟精子的最佳紫外线照射剂量为216mJ·cm⁻²。
