为深入了解主余序列对重力坝损伤特性的影响,依托某拟建重力坝,采用混凝土塑性损伤模型,根据规范反应谱拟合了30条人造主余震作为地震动输入,以损伤耗能为评价指标定量分析了主余震对大坝上部、坝踵以及大坝整体的损伤累积破坏的影响。研究表明:余震更易加深大坝上部的损伤破坏程度,其中使大坝上部的损伤程度增加了15.8%,使大坝坝踵的损伤程度增加了6.9%,使大坝整体的损伤程度增加了9.3%;大坝在主余震作用下,有明显的二次破坏现象,在大坝的抗震设计中应重视主余震对结构产生的破坏效应。

Cu_(2)ZnSn(S,Se)_(4)(CZTSSe)薄膜中的应力是影响其柔性太阳电池弯曲稳定性的重要因素。采用电子束蒸发法在Cu_(2)ZnSnS_(4)(CZTS)金属预制层中蒸发不同厚度(20、40、60、80 nm)的Sb薄膜,并结合后硒化的方法对CZTSSe薄膜进行Sb掺杂。研究发现Sb掺杂可以有效改善CZTSSe薄膜的结晶质量,提高太阳电池的光电转换效率(PCE)和弯曲稳定性。当Sb掺杂层的厚度为40 nm时,可以在最大程度上提升CZTSSe薄膜的结晶质量,相比未掺杂Sb的情况,其残余应力从-3.93 GPa降低至-2.19 GPa,其太阳电池的PCE由2.04%提升至4.41%;在弯曲角度60°、弯曲100次后,柔性CZTSSe薄膜太阳电池的PCE仍能保持原有效率的89.8%以上,表现出优异的弯曲稳定性。
