简介:在这篇论文,韧性剧降裂开(DDC)在不同压力状态下面的在Inconel600同伴Filler金属82的危险性(FM82)被调查。Inconel600是有到一般腐蚀,局部性的腐蚀,和压力腐蚀的优秀抵抗的Ni-Cr-Fe合金,它广泛地尽最大努力被使用了植物。然而,同伴FM82被显示了产生在焊接过程的DDC。解决这个问题,这个工作主要集中于在焊接过程在FM82评估DDC危险性。首先,到破裂(STF)测试的紧张被用来在简单压力状态下面完成DDC标准,并且DDC的形成机制被解释。真实焊接是有复杂压力状态的一个过程。后来,强调状态在建筑群下面得到DDC危险性,关于焊接的多传递的模型借助于有限元素方法被建立。根据数字模拟结果,变丑和温度历史的关系被完成。而且,易受影响的地点和时刻能被决定把结果与STF联系了。模拟结果相当适合从另一研究焊接实验。

简介:摘要:DRGs+DIP为一种深化支付方式的改革措施,为推动公立医院改革、提高院内质量的重要手段。DRGs+DIP的深化改革在优化院内各方面能力的同时也带来了相应的挑战。当前医疗的体质改革已迈入了比较急迫的环节,因此对于诊疗体系的改革建设刻不容缓。由于国内有关DRGs+DIP的研究实践起步较晚,缺乏规范全面性,基于此,本文针对近年来DRGs+DIP试点的公立医院展开研究,分析DRGs+DIP如何助推公立医院的高质量发展。
简介:【摘要】目的:DIP支付下严格执行国家医疗保障基金使用监督管理条例,以大数据支撑,精准识别不合理收费,(不重费、超标准收费、分解项目收费,串换收费)等,做到问题早发现、及时整改,精准监管,规范诊疗服务行为,合理检查、合理治疗,确保医保基金安全、高效、合理使用。方法:针对2021年飞检反馈问题93项、遵义市举一反三要求自查问题29项、审计反馈问题21项,2020年年度考核问题27项,以及院内举一反三自查存在问题;医院成立以党委书记、院长为组长,分管院长主抓的医保专班检查组,按飞检的检查方式进行检查,落实整改。结果:护理组:年度调取约1000万条数据、覆盖57个科室,抽查病例数约3000-4000例。未整改彻底的问题:气压治疗超部位收费;从入院到出院均按I级护理收;收取一次性导尿费用同时收取留置导尿费用;整改结果:2021年12月:调取数据30万余条,违规数据15条,合格率达99.99%;抽查病例246份,违规病例19例,合格率达92.28%.平均合格率:96.14%。
