Heterogeneous catalytic combustion provides a feasible technique for high efficient methane *** ABO_3-type materials have received renewed attention as a potential alternative for noble metals supported catalysts in catalytic methane combustion due to excellent hydrothermal stability and sulfur resistance. Recently, the emergence of nanostructured perovskite oxides（such as threedimensional ordered nanostructure, nano-array structure） with outstanding catalytic activity has further driven methane catalytic combustion research into spotlight. In this review, we summarize the recent development of nanostructured perovskite oxide catalysts for methane combustion, and shed some light on the rational design of high efficient nanostructured perovskite catalysts via lattice oxygen activation,lattice oxygen mobility and materials morphology engineering. The emergent issues needed to be addressed on perovskite catalysts were also proposed.

OBJECTIVE: To evaluate the efficacy and safety of gandouling plus sodium dimercaptosulphonate(DMPS) on neurological Wilson's disease(WD) in ***: We retrospectively evaluated the clinical records of 125 WD patients with neurological syndromes who were treated with gandouling plus sodium DMPS or DMPS used alone. All patients had a history of neurological deterioration during their diseases courses. The clinical efficacies, adverse reactions, and results of the various hematological and biochemical investigations were recorded for statistical ***: 92.30%(60 patients) of the WD patients treated with the combined therapy experienced an improved or stable neurological condition paral-leled by a significantly improved GAS score. Meanwhile, the WBC and PLT counts stabilized, liver function and renal function were improved or remained stable. The combined therapy also obviously promoted the 24-h urinary copper excretion. In particular, only 30.76% of the WD patients experienced mild adverse reactions, including neurological deterioration in 5 patients(7.69%), hepatic worsening in 1 subject(1.89%), which was less frequently than those in the control group treated with DMPS ***: Our findings indicate that the safety and efficacy of gandou-ling plus DMPS is superior to those of DMPS used alone in the WD patients with neurological symptoms.

Due to the technology limitation and inferior deNO_(x) efficiency of urea selective catalytic reduction (SCR) catalysts at low temperatures, passive NO_(x) adsorber (PNA) for decrease of NO_(x), CO and hydrocarbons (HCs) during “cold start” of vehicles was proposed to meet the further tighten NO_(x) emission regulations in future. Among them, Pd modified zeolite PNA materials have received more attention because of their excellent NO_(x) storage capacity, anti-poisoning and hydrothermal stability and since Pd/zeolite PNA was proposed, a variety of advanced characterization methods have been applied to investigate its adsorption behavior and structure-performance relationship. The comprehension of the active sites and adsorption chemistry of Pd/zeolite PNA was also significantly improved. However, there are few reviews that systematically summarize the recent progress and application challenges in atomic-level understanding of this material. In this review, we summarized the latest research progress of Pd/zeolite PNA, including active adsorption sites, adsorption mechanism, material physicochemical properties, preparation methods, storage and release performance and structure-performance relationships. In addition, the deactivation challenges faced by Pd/zeolite PNA in practical applications, such as chemical poisoning, high temperature hydrothermal aging deactivation, etc., were also discussed at the micro-level, and some possible effective countermeasures are given. Besides, some possible improvements and research hotspots were put forward, which could be helpful for designing and constructing more efficient PNA materials for meeting the ultra-low NO_(x) emission regulation in the future.

The Optimized Design of the Integrated Navigation Filter

第三十九届中国控制会议

作者： yanbing guo Lingjuan miao Xi Zhang China Academy of Electronics and Information Technology China Electronics Technology Group Corporation School of Automation Beijing Institute of Technology

Since the raw pseudorange and pseudorange rate are taken as the measurements, the measurement equation of the tightly coupled SINS/GPS integrated navigation system is nonlinear. As a typical non-linear filtering algorithm, the Extended Kalman Filtering（EKF） linearizes the measurements and has high estimation accuracy in the tightly coupled SINS/GPS integrated navigation system. The state vector of the tightly coupled SINS/GPS integrated navigation system includes the states of two subsystems, therefore the dimension of the state vector is high. The dimension of the measurement vector depends on the number of received satellite signals. If many satellite signals are received, the dimension of the measurement vector is high. The high dimensions of the state vector and measurement vector will result in large computation load for the EKF. To solve this problem, this paper proposes an optimized filtering scheme based on the two-stage Kalman filtering and sequential Kalman filtering. In that case, the estimation accuracy is not seriously affected while the computation load is significantly reduced. The semi-physical simulation results prove the estimation accuracy of the proposed optimized filtering scheme.

关键词： tightly coupled EKF computation load two-stage Kalman filtering sequential Kalman filtering optimized filtering scheme

中国古代驿制,历代虽有不同,但无疑都与传统的农业经济形态相依相存,它是中国古代最重要的交通运输组织,随着漫长岁月的洗礼而不断地成熟和完善。驿夫是驿站的组织细胞,是驿站运营的主体力量,驿站运营的好坏与驿夫的充足与否紧密相连,而驿夫的命运亦与驿站的生存状态休戚相关。不过,不同时代驿站的发展及驿夫的命运亦有差异,汉唐盛世,国强民富,驿站国营,驿夫待遇颇丰。元明两代,国库紧缺,驿站费用,全系民承,加之腐败丛生,驿夫生活苦不堪言。由此观之,驿夫命运之升沉也与各代皇权统治之盛衰密不可分。

针对二次调节加载系统结构复杂、存在耦合干扰等问题,提出一种基于自适应反推滑模算法(ABM)的二次调节加载系统控制器。根据系统原理建立了含有不确定性干扰的转速系统的动态数学模型,基于反推法设计控制器,引入滑模变结构控制率以避免传统反推控制中存在的计算膨胀和干扰抑制不彻底等问题。考虑到滑模变结构控制可能引起的抖振,引入自适应控制策略,对系统的耦合干扰等不确定性进行估计,提高系统的鲁棒性。利用Barbalat引理对系统稳定性进行验证,然后对系统进行仿真分析。研究结果表明:设计的控制器可以使系统在受到强烈干扰的情况下获得优良的跟踪性能。

津渡作为一种特殊的道路类型,曾是黄河两岸经济沟通和文化交流的重要通道,也是理解流域社会文化变迁的重要视角。通过对连通山西、陕西两个主要渡口——夏阳渡和吴王渡的田野调查发现,两个津渡古村经历了因“渡”而生、因“路”而变、因“桥”而兴的演变过程,在以“渡口”“公路”“桥梁”等通道为推动力的转型发展中,两个古村依托各自所嵌入的资源条件和地域文脉,分别形成了以水为中心的夏阳渡模式和以土为中心的吴王渡模式,成为乡村振兴背景下一种独特的发展经验,也为更好地传承和创新地方传统提供了个案参考和经验借鉴。

基于5批829项数据,以山西省非物质文化遗产为研究对象,利用GIS空间分析、区位熵及地理探测器方法,旨在明确山西省非物质文化遗产的空间分异及影响因素,为非物质文化遗产的保护利用提供参考。研究表明:1)山西省非物质文化遗产呈“两核两带”的倒“V”形集聚分布,其中传统音乐、传统体育、游艺与杂技、传统医药3类项目的局部集聚特征明显,而民间文学、传统音乐、传统戏剧、传统美术作为山西省的优势项目,保护利用潜质最大。2)除政策因素外,人文因素的影响显著高于经济和自然因素,其中地域文脉与交通条件等因素为非物质文化遗产的保护利用提供了关键支撑。3)山西省非物质文化遗产沿河流和交通分布特征明显,加强对沿线非物质文化遗产的保护利用,对促进黄河、长城国家文化公园建设、打造“黄河、长城、太行”三大旅游板块,构建汾河历史文化遗产廊道、推动太忻一体化经济区建设等具有重要意义。
