Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：复杂系统GO法可靠性关键技术
复杂系统 GO法 可靠性关键技术
2023/4/28
针对具有多故障模式、复杂相关性、多输入闭环反馈、多状态性能稳定单元等特性的多功能可修系统,系统性地完善了基于GO法的复杂系统可靠性建模与分析方法,并在此基础上首次提出了基于GO法的复杂系统可靠性优化分配方法和基于GO法的复杂系统可靠性评估方法,形成了复杂系统GO法可靠性一体化技术的雏形,开发了相应的GO法可靠性一体化技术软件。所获成果极大地改进了GO法理论,而且拓宽了GO法理论与技术的应用范围。
中国科学技术大学物理学院彭新华研究组和华中科技大学吕新友教授合作，在超辐射相变量子模拟的实验研究中取得重要进展。该合作研究组通过引入反压缩操作，借助于高精度的量子控制技术，首次成功地在核磁共振量子模拟器上实验实现了超越No-go定理的平衡态超辐射相变，推动了量子相变理论和量子模拟领域的发展，为量子精密测量提供了新的途径。相关研究成果于11月1日以“Experimental quantum simu...
以丙烯酰胺（AM）为单体，壳聚糖（CS）与氧化石墨烯（GO）为功能组分，N,N'-亚甲基双丙烯酰胺（MBA）为交联剂，通过自由基聚合法制备PAM/CS/GO水凝胶。采用傅里叶变换红外（FT-IR）光谱、X射线衍射（XRD）仪、扫描电镜（SEM）和万能试验机对水凝胶的结构与性能进行测试与表征。利用石英晶体微天平（QCM）研究该水凝胶薄膜在不同湿度条件下的吸湿行为。实验结果表明：相对于PAM/CS水凝...
