Purpose: Use the psychological resilience development model to formulate effective nursing measures, and explore the impact of relevant nursing measures on the psychological resilience and post-traumatic growth of patients. Methods: Using a general data sheet, post-traumatic growth scale, and psychological resilience scale, 100 patients discharged from the hospital after esophageal cancer were investigated in groups, and statistical software spss26.0 was used for statistical analysis. Results: The psychological resilience and post-traumatic growth levels of the experimental group were significantly higher than those of the control group, the P-value. Conclusion: As a common gastrointestinal tumor, esophageal cancer is traumatized by surgery. Not only will there be more discomfort during hospitalization, but also a series of complications will still occur after discharge, such as pain, weakness, and other discomforts, which will cause the patient’s emotions. Subject to strong fluctuations, the patient suffers great psychological trauma. After being discharged from the hospital, caregivers need to master more related skills when caring for patients, which is time-consuming and labor-intensive, and often causes the patients to feel the emotion of dragging the family members. Under the condition of both physical and psychological pressure, patients often appear fearful and uneasy, and suffer great psychological trauma, which leads to low levels of psychological resilience and post-traumatic growth of patients, and related nursing interventions based on Rutter’s psychological development model It can significantly improve the patient’s psychological flexibility, improve the patient’s post-traumatic growth level, promote the patient’s physical and mental recovery, make the patient produce positive emotions, increase positive psychological changes, and thereby improve the patient’s quality of life after discharge.

NiCoV面心立方(FCC)单相中熵合金展现出卓越的强度和延展性,是一种极具应用潜力的结构材料。本研究采用放电等离子烧结(SPS)技术制备NiCoV合金,这一技术以其快速加热、低烧结温度和高产品致密度等优点而著称,特别适合于快速制备具有细小晶粒的高性能合金。通过对粉末进行球磨处理,消除了合金制备过程中的孔隙缺陷。在随后的热轧处理中,合金中沿晶界分布的硬质相得以重新排布,形成了具有大量位错亚结构、纳米孪晶和均匀分布硬质相的复合微观结构。这种结构有别于传统熔铸方法得到的均匀FCC单相结构的NiCoV合金。SPS工艺结合热轧处理所产生的复合微观结构,通过位错、析出相、纳米孪晶和晶界的多维度协同强化作用,使得合金的屈服强度达到1 360 MPa,抗拉强度达到1 593 MPa,同时保持了18.7%的均匀延伸率,实现了优异的强塑性匹配。这项研究不仅优化了NiCoV合金的微观结构和力学性能,还为高性能中熵合金的制备提供了一种新途径。

立足于中国505个连片贫困县的县域样本数据,从邻居贫困县外部性和目标贫困县外部性视角考察多维资本对我国连片贫困县经济增长的影响。研究发现:土地资本、物质资本、公共服务资本、政府行为以及技术进步都能通过直接效应显著促进目标贫困县自身经济增长;邻居贫困县中的土地资本、物质资本、公共服务资本以及技术进步都存在正邻居贫困县外部性,而人力资本和地方政府支出则对目标贫困的经济增长具有显著的负邻居贫困县外部性;目标贫困县的耕地资本、物质资本、公共服务资本、技术进步、地方政府支出都能通过正目标贫困县外部性显著促进邻居区域经济增长。同时,在稳健性检验的GNS模型中,土地资本、技术进步以及政府支出的对邻居贫困县的正外部性以及人力资本的负外部性都处于富有弹性区域。

Synchronization is an essential technology in the radio navigation system. The technique for improving the “Beidou” positioning ability is presented through constituting the terrestrial improvement system, and the beacon synchronization of the improvement system with the “Beidou” one-way time transfer model is *** direct digital synthesis (DDS) is adopted to generate the pseudo-random code clock having high precision and stability. Meanwhile, the CPLD device is used to design the synchronization pulse picking-up module, the spread spectrum PN code generator and the spread spectrum modulator. Measurement results indicate that the beacon synchronization has the high precision and the stability.

立足于马克思主义政治经济学视角,使用空间计量回归方法剖析中国区域经济增长的动态关联与时空分异特征。研究发现,一是区域经济增长自身不仅在时间维度上呈现“路径依赖”的动态关联特征,还在空间维度上受到其他邻近地区经济增长的空间外溢作用,使其表现出自我强化态势。二是资本有机构成提高会因其技术进步特征而推动目标地区或邻居地区的经济增长,又会因其内部结构中不变资本与可变资本变动而抑制本地区及其他邻居地区的经济增长,并且它在东部地区更能表现出显著的正向经济增长效应。三是交通便利程度、劳动复杂程度和外贸进口规模不仅能够直接推动目标区域经济增长,其时间和空间的时空累积效应均会对区域经济短期和长期增长产生显著影响,且具有一定的空间差异性。
