For the materials, which have no cyclic steady stage but exhibit cyclic softening, this method isn't suitable to determine the low cycle fatigue damage with the change of stress. 對沒(méi)有明顯循環(huán)穩定階段并表現為循環(huán)軟化響應行為的材料，不適合用應力的變化來(lái)定量的反映材料低周疲勞的損傷過(guò)程。
Experiments were carried out to study the effect of two extracts of maize plumule on resistance to oxidation damage, pathological change on Bombyx mori, and on protection of cells. 摘要研究了兩種玉米幼芽提取物對家蠶抵抗氧化損傷過(guò)程中相應病理學(xué)變化的影響，以及對細胞的保護作用機制。
