The development of hospital information has been carried out for nearly 50 years, and originally started Le hospital information system （HIS）1 So far HIS isas the hospital information system （HIS）J So far HIS is the most widely and deeply used management system for hospitals in China.2 ＂General function standard for hospital information system＂ issued by China＇s Ministry of Health in 2002 defined that ＂The hospital information system refers to using of computer hardware and software technology, network communications technology, and other modem technology to comprehensively manage personnel, logistics, and finance in various departments in hospital. Gather, store, treat, extract, transport, aggregate,and process data in various stages of the medical activities, so that provide comprehensive and automatic information management and service to the hospital.＂

介绍了航空发动机联轴器TC4钛合金膜盘振动疲劳的试验研究。通过建立闭环控制下的振动疲劳试验系统,得到了该膜盘在不同激励条件下的频率-位移响应曲线,由此阐明了联轴器膜盘在大挠度条件下的非线性振动特性。基于该特性进一步开展膜盘在非线性振动条件下的振动疲劳试验研究,给出了该膜盘的径向应力-疲劳寿命曲线以及疲劳极限值。最后分析了膜盘振动疲劳的主要破坏形式。结果表明,膜盘疲劳极限值介于其母体材料的中值疲劳极限值和高可靠度疲劳极限值之间,而主要破坏形式包括可见表面裂纹和表面剥落。

对低压电力线载波通信路由器的优化设计,可以有效提高通信路由可靠性。对载波通信路由器的设计,需要应用蚁群算法进行路径寻优,建立网关节点与网络内任意节点通信的最优路径。传统方法结合了变异遗传算法、蚁群算法等几种智能算法,但没有建立节点通信的最优路径,导致路由器设计效果不理想。提出基于分簇蛛网的路由算法。首先介绍了低压电力线的网络拓扑及其组网的必要性;然后描述了传统非交叠分簇算法和人工蛛网拓扑,详细阐述了分簇蛛网组网方法并采用此方法对低压电力线通信网络进行组网;应用蚁群算法进行路径寻优,建立网关节点与网络内任意节点通信的最优路径。仿真就算法的迭代次数的路径时延、丢包率和跳数进行对比分析,结果表明,基于分簇蛛网组网的蚁群路由算法提高了算法效率,提升了通信的可靠性,具有一定的实用意义。

The conventional design of metal-organic frameworks (MOFs) with room-temperature phosphorescence (RTP) mostly relies on using heavy metals,as the heavy atom effect can effectively increase the efficiency of intersystem crossing (ISC) to get a better phosphorescence *** the first time,we reported the highly efficient RTP of a lithium-based MOF IMU-101 with a lifetime (τ) of 299 ms and a quantum yield (QY) of 4.91%.In addition,MOFs IMU-102 and IMU-103,with sodium and cesium as metal nodes,were successfully *** phosphorescence properties of this series of alkali metal MOFs were systematically studied and *** crystallography and computational calculation show that the mechanism for achieving RTP for this material lies in the ultrashort coordination bond of Li,which enables the reduction of non-radiative ***-101,as a cheap and environmentally friendly room-temperature phosphorescent material,has been further developed into composite polymer inks and bulk *** makes them promising for applications in anti-counterfeiting and information encryption.
