道床清筛后进行捣固和稳定作业,是确保施工线路恢复正常行车的重要措施。重载铁路清筛施工中常用“三捣两稳”和“四捣三稳”作业模式。为从理论上了解2种作业模式的作用效应,建立清筛后有砟道床离散元模型,模拟大型养路机械捣固和稳定作业,分析2种作业模式对有砟道床密实度、垂向刚度、横向阻力等力学特性的影响。结果表明:通过捣固和稳定作业,有砟道床状态得到全面提升。在“三捣两稳”和“四捣三稳”作业模式下,道床密实度由50.25%分别提升至58.61%、59.65%;道床垂向刚度由15.70 kN/mm分别提升至50.09 kN/mm、60.15 kN/mm;道床横向阻力由2.546 kN分别提升至3.672 kN、3.465 kN。

Phase selection and microstructure evolution of the undercooled eutectic Ti-Si alloy were systematically investigated by the electromagnetic levitation method, and the maximum undercooling achieved was 318 K(0.2 TE). The migration of the liquidsolid interface was in-situ detected by a high-speed camera system. When the undercooling is smaller than 140 K, the liquid-solid interface is smooth. Once the undercooling arrives at 230 K, the liquid-solid interface is irregular, which reflects the growth transition from the solute control to the combined controls of solute and thermal. The eutectic growth velocity increases as an exponential function of undercooling. The electromagnetic stirring effect makes it difficult to increase undercooling, but plays an important role in accelerating the eutectic reaction velocity at low and moderate undercoolings. Primary dendritic β-Ti phase appears in the solidified alloy from 63 to 176 K undercoolings, and the microstructure is completely composed of eutectic once the undercoolings increase up to 230 K. When the undercoolings exceed 273 K, the microstructure consists of uniformly distributed irregular eutectic. For the drop tube experiments, the microstructures composed of a large amount of dendritic α-Ti phase and eutectic phase are found in a wide range of diameters from 69 to 725 μm. As the decrease of diameter, the solubility of Si in the dendritic α-Ti phase dramatically increases from 6.80% to 10.73%, and the ratio of the area occupied by the dendritic α-Ti on a cross-section of solidified alloy obviously increases from 23.52% to 41.02%, which result from the combined effects of high undercooling and large cooling rate.

目的探讨结直肠腺瘤性息肉与糖尿病及糖代谢相关分子的关系。方法收集2019年6月到2021年9月山东省肿瘤医院内镜科进行内镜下息肉切除术的40例患者,其中炎症性息肉27例,腺瘤性息肉13例。测量这些患者的空腹胰岛素、空腹血糖以及息肉组织中成纤维细胞生长因子19(FGF-19)和胰岛素样生长因子1(IGF-1)mRNA的表达。采用单因素和多因素logistic回归分析明确腺瘤性息肉发生的影响因素,基于多因素logistic回归分析结果构建预测腺瘤性息肉发生的列线图模型,并对模型进行区分度、校准度和临床适用性评价。结果腺瘤性息肉组患者的血糖、胰岛素、FGF-19和IGF-1的相对表达量分别为(8.67±2.70)mmol/L、(12.72±7.69)μU/L、2.20±1.88和1.36±0.69,均高于炎症性息肉组[分别为(5.51±0.72)mmol/L、(5.49±2.68)μU/L、0.53±0.97和0.41±0.46,均P=0.001]。多因素logistic回归分析显示,IGF-1的相对表达量为结直肠腺瘤性息肉发生的独立危险因素(OR=5.622,95%CI:1.085~29.126)。根据多因素logistic回归分析结果成功构建腺瘤性息肉的预测列线图模型。列线图模型的C指数为0.849,表明列线图模型的区分度较好。校准曲线显示,列线图模型的预测概率与实际观测结果的一致性尚可。临床决策曲线显示,列线图模型有一定的临床适用性。结论结直肠腺瘤性息肉的发生与糖代谢有关,糖尿病患者容易发生结直肠腺瘤。
