目的针对TNM-TiAl合金(Ti-43.5Al-4Nb-1Mo-0.1B)服役时受高周疲劳影响的问题,揭示喷丸处理技术对TNM-TiAl合金疲劳性能的影响规律。方法通过扫描电镜和透射电镜分析喷丸前后的组织演变,测量喷丸前后合金表面残余应力、表面粗糙度和显微硬度分布规律,采用梯度法测量喷丸前后的高周疲劳极限,并分析断口形貌和断口附近组织。结果喷丸后合金表面粗糙并且存在烧蚀坑,表面附近的片层团发生弯曲,在组织内部引入大量位错、位错缠结以及位错胞等缺陷。喷丸后表面粗糙度明显提高,显微硬度提高了209HV0.05,从表面到内部形成深度为260μm的硬度梯度。喷丸后试样表面的残余压应力为446 MPa,深度约为85μm。喷丸后在450℃下保温30 h后合金表面最大硬度仍比喷丸前的硬度高166HV0.05,硬化深度约为150μm。未喷丸光滑试样、喷丸光滑试样、未喷丸缺口试样和喷丸缺口试样的疲劳极限分别为615、637、385、455 MPa,光滑试样断裂类型为穿晶解理型脆性断裂,而缺口试样为穿晶脆性断裂。结论喷丸能够显著提高最大残余压应力和引入应力的深度,且喷丸引入的组织具有一定的热稳定性,喷丸明显提高了TNM-TiAl合金的疲劳极限。

针对目前实验室用MnO_(2)与浓HCl反应制取氯气实验存在反应物用量没有说明,反应原理学生不易理解,现象不明显等缺陷,提出了实验室用K_(2)S_(2)O_(8)与HCl反应制备氯气,并利用正交试验法探讨了实验室用K_(2)S_(2)O_(8)与HCl反应制取氯气的最佳工艺条件。实验表明:用K_(2)S_(2)O_(8)与HCl反应制取氯气,避免了MnO_(2)与浓HCl共热制取氯气实验中的缺陷,且实验现象明显,反应速率适中,完全满足了课堂演示和学生实验的要求。因此,建议中学化学教学中选用该方法为制备氯气的课堂演示实验或学生实验。

通用场景文本检测被广泛应用于地图导航、无人驾驶等多个领域。场景文本方向各异且形状复杂多变,使得文本检测难度大。针对这一问题,提出一种高阶图卷积推理网络。以文本检测框架DRRG为基础,设计高阶图方案,提出高阶图卷积推理网络,扩展了推理范围,有效组合高阶邻居提供的辅助信息。改进一阶邻居的设置,降低无关组件的干扰,提高了反向传播和组件链接的效率。引入SE聚合模块为每个节点独立且自适应地生成聚合方案,进一步提高了对高阶信息的利用率。实验结果表明,改进后的网络在Total-Text、CTW-1500和ICDAR2015数据集上的平均精度(F1)分别提升了1.4、1.05和1.26个百分点。
