从衰老的角度研究了紫外线对蜘蛛Nephila clavata不同生命阶段分泌的拖线的影响。通过电子自旋共振ESR方法测量由于蛋白质分子降解而产生的自由基作为紫外线照射时间和蜘蛛年龄的函数。研究发现，成熟蜘蛛的拖线自由基强度大于幼年蜘蛛。这一发现表明，对于老蜘蛛分泌的丝来说，应该考虑老化的情况。
Effect of ultraviolet rays on drag lines, which were secreted at different life stages of spider Nephila clavata, was studied from the aging point of view. The radicals due to the degradation of protein molecules were measured as a function of the irradiation time of ultraviolet rays and the spider age by the electron spin resonance ESR method. It was found that the radical intensity for drag lines from the mature spiders was larger than that from the juvenile spiders. This finding suggests that the aging should be considered for the silks secreted from the old spiders.
