轫致辐射作为原子物理中重要的辐射过程,在天体物理、等离子体物理、磁约束和惯性约束核聚变等领域具有重要研究意义.本文基于相对论分波展开方法研究了中高能电子碰撞中性碳原子以及各价态碳离子的轫致辐射过程,并探讨电子屏蔽效应对轫致辐射截面及角分布的影响.利用Dirac-Hartree-Fock理论构建靶原子波函数,在中心场近似下建立电子-靶原子相互作用势,基于相对论分波展开方法通过数值求解Dirac方程得到电子连续态波函数,对不同价态碳离子的轫致辐射单重、双重微分截面以及角分布函数进行详细计算,分析电子屏蔽效应在不同入射电子能量和出射光子能量下的作用.结果表明,电子屏蔽效应会使轫致辐射单重和双重微分截面降低,在较低能电子入射时以及软光子区域抑制效果显著,而随着入射电子能量和出射光子能量的增加,电子屏蔽效应不断减弱.电子屏蔽效应对轫致辐射角分布的影响则较不明显.

目的早疫病是茄科作物生长过程中的一种常见破坏性病害,严重时会导致作物欠收而损失严重,传统的作物病害检测方法难以在病害潜育期及时发现病害特征从而采取科学有效的防治措施。本文通过高光谱成像仪连续监测从而获得不同感染期辣椒早疫病的高光谱图像,利用光谱角余弦-相关系数和切比雪夫距离确定了辣椒早疫病潜育期最早可识别时间(本实验潜育期最早可识别时间为接种后24h)。方法以辣椒早疫病潜育期病状作为研究对象,采用遗传算法筛选出13个特征波长,经特征波长优化组合并结合逻辑回归模型建立基于光谱特征的作物病害潜育期病状识别模型。同时,利用局部二值模式建立基于图像纹理特征的辣椒早疫病潜育期识别模型。结果实验以120个样本进行测试,基于光谱特征的作物病害潜育期病状检测识别模型在训练集和测试集的准确率均达到93%以上,基于纹理特征的作物病害潜育期病状检测识别模型在训练集和测试集的准确率分别达到了98.96%和100%。结论利用光谱特征或者纹理特征均可实现作物病害潜育期病状的检测识别,纹理特征相比光谱特征更显著地揭示了病害潜育期特征,有效提升了模型检测性能。本文研究成果可为其他作物病害潜育期病状的监测识别提供理论参考。

Net ecosystem productivity(NEP)is an important indicator for evaluating carbon sources and sinks in regional ecosystems. Clarifying its spatiotemporal differentiation pattern and driving mechanisms is crucial for precise protection and restoration of the Beijing-Tianjin-Hebei ecosystem. We estimated the net ecosystem productivity(NEP)based on MODIS remote sensing data and explored the spatial and temporal patterns of carbon sequestration benefits and succession patterns in the Beijing-Tianjin-Hebei Region from 2002 to 2020 by using Sen’s trend + MK test,Hurst index,and center of gravity shift and quantitatively separated the relative contributions of carbon sequestration benefits driven by human activities and climate change by using bias correlation,complex correlation,and residual analysis. The relative contributions of anthropogenic activities and climate change in driving the spatial and temporal changes in carbon sequestration were quantitatively separated using partial correlation and residual analysis. The results showed that:① NEP in the Beijing-Tianjin-Hebei Region showed an increasing trend year by year over the past 20 years,with a growth rate(in terms of C)of 3.066 4 g·(m2·a)-1,and the spatial manifestation was high in the northwest and low in the southeast;the areas with strong carbon sink capacity were mainly concentrated in the periphery of Zhangjiakou City and Chengde City,and those with a strong carbon source effect were distributed in the regions of Tianjin and Handan. More than 80% of the regional carbon sink capacity was on the rise,with 47.45% and 8.29% of the regions showing very significant and significant increases,respectively,especially in Zhangjiakou and Chengde;however,the future growth trend was gradually slowing down. The center of gravity of carbon sources was gradually shifting to the southeastern plains,while the center of gravity of carbon sinks was shifting from the northeast to the southwest. ② More than 50% of the regions showed

藏彝走廊边缘地带的泸定岚安乡G家《宗支簿》记录和当事人回忆数百年间婚俗。G家《宗支簿》中的记载表明泸定岚安的通婚范围呈现逐渐扩大的趋势,存在婚后分家、曾实行一夫多妻制、入赘婚和嫁入后改姓名等习俗。在G家人对1950年以来的婚俗的记忆中,婚恋模式从包办婚姻转变为自由恋爱,婚礼过程经历了简化流程到恢复传统再到改革创新的过程,婚宴也由简单变为复杂。从婚俗变迁历史和当下两个角度看,传统婚俗文化是各民族婚俗的基础,婚俗是社会文化生态变化的晴雨表,婚俗在传统约束力和个体创新力共同作用下传承,国家对婚俗变迁有巨大引导作用。

目的探讨旋毛虫(trichinella spiralis,Ts)蛋白对脂多糖(lipopolysaccharide,LPS)诱导巨噬细胞株RAW264.7产生炎症反应的影响及其机制。方法通过LPS刺激RAW264.7细胞建立炎症模型,实验共分为4组:对照(negative control,NC)组、Ts组(Ts 2 mg·L^(-1))、LPS处理组(LPS 1 mg·L^(-1))、Ts+LPS组(Ts 2 mg·L^(-1)+LPS 1 mg·L^(-1))。qRT-PCR检测巨噬细胞极化分子标志物iNOS、Arg1以及炎症因子IL-1β、IL-6的表达,Western blot检测IL-1β、IL-6、BRD2蛋白表达,免疫荧光实验检测BRD2。为探索Ts蛋白抑制炎症是否通过BRD2发挥作用,我们用siRNA靶向敲低BRD2分子,再次分组实验,qRT-PCR检测 iNOS、Arg1、IL-1β、IL-6 的表达,Western blot检测IL-1β、IL-6的表达。结果与对照组相比,LPS促进iNOS、IL-1β、IL-6及BRD2的表达,Ts蛋白干预可降低iNOS、IL-1β、IL-6、BRD2的表达。敲低 BRD2 后,Ts蛋白进一步降低iNOS,而Arg1、IL-1β、IL-6水平有所上升。结论 Ts蛋白通过调控巨噬细胞极化、抑制BRD2从而缓解LPS诱导的巨噬细胞炎症反应。
