Malignant neoplasms consistently pose a significant threat to global public health [1,2]. In recent years, immunotherapy has demonstrated remarkable clinical success; however, its efficacy is limited by the scarcity of immune cell infiltration within tumor microenvironments. Cell pyroptosis, a gasdermin-mediated process characterized by cellular swelling,rupture, and the release of intracellular contents such as IL-1β, IL-18, ATP, HMGB1, plays a crucial role in this context[3,4].

重轨轨头的廓形精度是衡量高速铁路用钢轨质量水平的重要指标之一。采用有限元方法对半万能工艺下UF轧制过程进行了模拟,通过对比实验,分析了来料宽度、水平辊压下量及腹高差值变化对轨头与轨腰间金属横向流动及轨头廓形成形精度的影响。结果表明,轨头部分来料宽度变化对轨头与轨腰间金属横向流动基本无影响;水平辊压下使轨腰金属向轨头流动,使轨头展宽量增大;腹高差值使轨头金属向轨腰流动,使轨头展宽量减小,在两者综合作用下,轨头金属最终向轨腰流动,造成轨头金属量减少,孔型设计时应考虑此偏差造成的头腰延伸率不匹配及廓形充满度问题。轨头部分来料宽度变化会直接改变轨头金属量进而影响其廓形精度,孔型过充满后,来料宽度增加引起的轨头展宽量显著增加;腹高差值过大或水平辊压下量过大均会加剧轨头与轨腰间金属横向流动,不利于降低钢轨轧后残余应力。
