The present work studied the corrosion properties around the fusion boundaries of 2.25Cr-1Mo steel with stainless steel strip overlay joints under as welded condition and after post-weld heat treatment (PWHT) in H2 S containing solution (NACE TM-01-77 standard) with different time. An in-situ observation method was introduced for evaluating corrosive progress in the fusion boundary in H2 S containing solution, that is, the samples were marked firstly at the boundary and then treated in the solution for variant time. Each time after the corrosion treatment, the observations were kept to focus at the same marked area by using scanning electron microscopy (SEM) to observe the corrosion progress. The results reveal that the fusion boundary is the worst region for corrosion resistance when comparing with other boundaries, and a broad fusion boundary has a stronger resistance for "hydrogen induced disbonding" than a narrow one.

基于中国家庭追踪调查2018年数据,选择Bivariate Probit模型和工具变量Probi t模型检验“健康风险-保险”的相关关系,并且研究补充医疗保险市场上的选择效应。研究结果显示,补充医疗保险市场上“健康风险-保险”的相关关系显著为负,自我评价相对健康的群体更倾向于参加补充医疗保险。使用更为客观的代理变量和调整后的住院费用作为健康风险的代理变量进行稳健性分析,确认了研究结果的稳健性。异质性分析结果表明,健康风险和风险厌恶共同解释了补充医疗保险市场上主要的选择效应为正向选择。在相对不完善的补充医疗保险市场上,个人信息是多维的,相对风险厌恶对参加补充医疗保险的决策会产生重要影响。

堆芯入口流场设计是小型固态燃料熔盐堆系统项目内容之一,它对反应堆结构的稳定性、堆芯温度和流场分布有着非常重要的影响。研究了熔盐流道流通面积变化对堆芯入口温度、流场分布及压降的影响,优化熔盐流道几何结构。以小型熔盐球床堆模型为研究对象,取符合实际边界条件的输入参数,通过改变熔盐流道流通面积,使用计算流体力学(Computational Fluid Dynamics,CFD)通用程序Fluent 16.0对堆芯入口内熔盐的热工水力特性进行数值模拟。在考虑实际下反射层流道的流通面积占比最大为18.14%下,研究了熔盐流道流通面积占比在区间[0,15.00%]变化。结果表明,堆芯活性区熔盐最高局部热点温度随熔盐流道流通面积比的增大而增高;堆芯入口内的压降随下反射层熔盐流道流通面积比的减小而增大;在径向方向上流进孔道的熔盐流速随着孔道远离堆芯位置而增大。本研究可为小型固态燃料球床熔盐堆优化设计提供一定的参考价值。

实现多层次医疗保障的有序衔接需要分析各项目间的互补关系。本文构建剩余风险指标,基于2018年中国健康与养老追踪调查数据,描述剩余风险对商业医疗保险中的选择效应的影响,实证分析选择效应的类型并解释其形成机制。剩余风险衡量个体选择性参保时面临的健康风险,即剔除多层次医疗保障可能降低的风险后剩余的健康风险。研究发现,商业医疗保险市场中的主要选择效应为正向选择,剩余风险较高者参保概率仅为较低者的60%,即多层次医疗保障水平较低且健康风险较高的个体反而参保概率较低。考虑多层次医疗保障与商业医疗保险的互补关系将使模型对参保行为的解释效力提升18%。通过控制遗漏变量、改变估计方法、替换剩余风险衡量指标和使用工具变量的方式确认了实证结果的稳健性。正向选择在年龄和家庭保障能力方面存在异质性,年龄较低、家庭储蓄水平和家庭经济水平较高的个体正向选择参保的概率较高。机制分析发现,风险厌恶可以解释正向选择现象,即风险厌恶程度较高者积极降低自身剩余风险且主动参加商业医疗保险使得市场中呈现“保险-剩余风险”的负相关关系。

2017年,我国开始试点生育保险和职工医疗保险合并实施。本文利用合成控制法,以两险合并实施的6个试点城市(主要是合肥市)为实验组,以33个非试点城市为控制组,构建2008—2018年的城市面板数据,分析两险合并实施对扩大生育保险覆盖面的净效应。结果显示,2017年,两险合并实施对合肥市生育保险覆盖面的净提升作用为10.30%,2018年为8.45%,试点效应明显。然而,2019年全国全面推开两险合并实施的效应明显较低。分析发现,灵活就业人员被明确纳入两险合并实施覆盖范围是合肥市两险合并实施试点成效显著的制度性原因。本文建议,可要求所有参加了职工医疗保险的人员(不论是否已经失业或是否灵活就业)均同步参加生育保险,推动职工养老保险在职职工参加生育保险,并逐步拓展到全体城镇就业人员。同时,应为生育保险所有参保人员提供生育津贴待遇,促进城镇(尤其是灵活)就业人员参加职工医疗保险,提升参保人的实际福利水平。

BACKGROUND Acquired hemophilia A (AHA) is a rare and potentially severe bleeding disordercaused by circulating autoantibodies against factor Ⅷ (FⅧ). In approximately50% of the patients, the condition is associated with autoimmune diseases,cancers, medication use, pregnancy, and the post-partum period. Bullous pemphigoid(BP) is a chronic autoimmune subepidermal blistering disease associatedwith tissue-bound and circulating autoantibodies against BP antigens 180 (BP180)and 230 (BP230). AHA-associated BP has a high mortality rate;hence, the understandingof this disease must *** SUMMARY A 69-year-old man presented with erythema, blisters, blood blisters, and crustsaccompanied by severe pruritus for more than 20 days, and ecchymosis andswelling on his left upper arm for 3 days. Pathological examination revealed asubepidermal blister that contained eosinophils. Laboratory tests showed that theBP180 autoantibody levels had increased, isolated activated partial thromboplastintime was notably prolonged (115.6 s), and coagulation FⅧ activity wasextremely low (< 1.0%). Furthermore, the FⅧ inhibitor titer had greatlyincreased (59.2 Bethesda units). Therefore, the patient was diagnosed as having BP associated with AHA, prescribed 0.05% topical halometasone cream, and transferred to a higher-level hospitalfor effective treatment;however, he died after 2 *** AHA associated BP is rare, dangerous, and has a high mortality rate. Therefore, its timely diagnosis and effectivetreatment are necessary.
