通过对掺入聚乙烯醇(PVA)纤维混凝土试件进行三点抗弯的声发射试验,研究其损伤失效机理。首先,通过三点弯曲试验,得到了PVA纤维腐蚀前后混凝土的抗弯强度。然后,基于加载全过程中声发射特征信号,根据声发射幅值、计数和能量相关图,并通过比较有无腐蚀PVA纤维混凝土声发射信号,揭示了PVA纤维腐蚀混凝土的抗弯强度下降原因及其损伤机理。最后,借鉴NDIS-2421定量评定标准分析声发射信号,对混凝土试件的损伤情况做出定性评价,分析PVA纤维在腐蚀前后混凝土中的作用;此外,通过计算声发射特征信号裕度指标,发现PVA纤维混凝土弯曲损伤明显分为三个阶段,未腐蚀PVA纤维混凝土试件的裕度值较均匀。

作者： Chonglu li Jianbo Zhan Biao dong Institute of Health Inspection and Testing Hubei Provincial Center for Disease Control and Prevention State Key Laboratory on Integrated Optoelectronics College of Electronic Science and Engineering Jilin University

Immunotherapy, as a groundbreaking cancer treatment, has gained considerable attention for its utilization of the body’s immune system to combat tumors [1]. This therapy induces tumor cell apoptosis, triggering a sustained anti-tumor immune response and effectively preventing tumor recurrence and metastasis [2]. The fundamental principle lies in inducing tumor cell death through specific treatment modalities, leading to the release of a cascade of signaling molecules and antigens, thereby mobilizing the immune system to actively identify and attack tumor cells [3].
