The design and performance analysis of networked control systems with random network delay in the forward channel is proposed, which are described in a state-space form. A new control scheme is used to overcome the effects of network transmission delay, which is termed networked predictive control （NPC）. Furthermore, three different ways to choose control input are discussed and the performances are analyzed, respectively. Both real-time simulations and practical experiments show the effectiveness of the control scheme.

目的观察宫腔镜电切术(transcervical resection of polyp,TCRP)联合左炔孕酮宫内节育系统(levonorgestrel intrauterine system,LNG-IUS)对子宫内膜息肉(endometrial polyp,EP)患者月经量及性激素水平的影响。方法选取2020年1月-2021年8月永修县人民医院收治的74例EP患者,随机分为两组,即对照组、观察组,每组各37例,对照组进行TCRP术治疗(术后进行常规药物治疗),基于此,观察组联合LNG-IUS治疗;于术前、术后3个月时,比较两组月经量;术前、术后3个月,比较两组性激素[黄体生成素(luteinizing hormone,LH)、卵泡刺激素(follicle-stimulating hormone,FSH)、雌二醇(Estogen,E_(2))]水平;记录随访1年两组复发率。结果术后3个月,观察组月经量少于对照组,有统计学差异(P0.05);观察组术后1年复发率低于对照组,有统计学差异(P<0.05)。结论TCRP联合LNG-IUS应用于EP患者中,能够减少月经量,改善性激素水平,降低复发率。

Micro turbine engine （MTE） is an important kind of propulsion system for miniature unmanned aircraft or missiles, because of its better high-speed performance （than propeller propulsion） and higher propulsion efficiency （obviously than rockets）. Windmill start is a common air-starting mode used in micro turbine engine. The windmill starting characteristics are important to the practical use of micro turbine engine. In this paper, the windmill starting characteristics research for a 12 cm diameter （MTE-D） micro turbine engine is carried out by experiment and numerical simulation. The characteristic of rotor mechanical losses at low-speed condition is stud- ied, and the engine common working line of windmill starting process is obtained. Based on the engine windmill characteristics, the propane ignition characteristics under different inflow conditions are researched, and the envelope of propane ignition and propane flameout is determined. The experimental research of fuel supply and ignition characteristics is completed, and the envelope of fuel supply and ignition is obtained. The windmill stage, propane ignition stage, fuel ignition stage and acceleration process from idling-speed to 80% full speed of MTE-D micro turbine engine is optimized, and the optimization windmill starting parameters are collected. The successful wind-mill starting experiment under this condition with engine speed up to 80% full speed indicates that these starting parameters are reasonable. All the starting parameters of MTE-D micro turbine engine obtained in this work are dimensionless parameters, and the conclusions obtained in this study have some reference to other micro turbine engines with the similar structural form and starting process.

铝形态对铝系混凝剂去除抗性基因的影响

抗生素抗性基因(ARGs)会对自然环境和人体健康造成潜在的巨大威胁,而污水处理厂的出水是环境ARGs主要来源之一.铝基混凝工艺可以有效削减出水中氮、磷等指标,然而对于ARGs的去除以及其中起主要作用的铝形态仍然不清楚.因此,本文首先对污水厂现有工艺段出水中的ARGs进行了调研,结果发现,在经过活性污泥工艺处理后ARGs的丰度出现明显提高,并且在最终的出水中sulⅠ和sulⅡ基因有较高残留.接着以sulⅠ和sulⅡ为模型物,研究了氯化铝(AlCl_(3))和聚合氯化铝(PAC)混凝剂对污水处理厂出水中ARGs和int I1基因的去除效果,探讨了不同的Al形态对ARGs去除效果的影响.结果发现,AlCl_(3)和PAC的混凝过程均能够有效去除ARGs,去除率为0.1~2.26-log.统计学相关分析发现,ARGs的去除主要是通过去除抗性细菌来实现,并且碱性条件下(pH为8或10)混凝过程对ARGs去除率较高,这表明ARGs的有效去除是通过铝水解产物尤其是无定形Al(OH)_(3)沉淀的吸附和网捕来实现,其中,AlCl_(3)中起主要作用的是单体铝和低聚态铝(Al_(5))物种,而PAC中则是单体铝和高聚合态Al_(13)发挥主要作用.
