利用理论计算方法设计高能量密度材料(HEDM)分子是目前材料科学领域的研究热点之一。本文利用密度泛函理论(DFT)在B3LYP/6-31G(d)水平上对N4O5团簇异构体几何结构进行优化,找到了N4O5团簇的12种稳定结构。以一个N4O5团簇分子分解为3个NO和1个NO2计算,N4O5团簇分子的解离能在10.66×103～6.099×103kJ/kg之间,放出的能量很多,是用做高能量密度材料的潜在资源。

现有近代史料仍支持黄梅戏的起源是湖北黄梅。基于“黄梅戏”“采茶调”“采茶戏”“黄梅腔”“黄梅调”等关键词,考查近代史料发现:“黄梅戏”一词最早见于1921年《宿松县志》;“采茶调”一词最早见于明代王云凤的诗,描绘的是陕西西安的民风,近代则最早见于1918年天津《益世报》;“采茶戏”最早出现在1818年嘉庆版《石门县志》;“黄梅腔”最早在1935年天津《北洋画报》中出现;“黄梅调”的新闻最早见于1879年《申报》。从相关史料可推断出,黄梅戏大约在1875-1879年传入安徽,名为“采茶小戏”或“黄梅戏”。“黄梅调”最早于1879年开始在安庆城外表演,1918年安庆城外始有戏园表演,1922年安庆城内始有戏班上演;“採茶戏”最早于1887年在江西九江城外上演。史料中关于黄梅戏的称呼多为“淫戏”,屡遭禁演但屡禁不绝。相比安徽其他城市,安庆城是最早接纳黄梅戏之地。黄梅戏从安庆开始快速发展,逐渐摆脱过去乡村酬神模式,成为新的戏曲形式。

Macrophages are crucial for a successful pregnancy, and malfunctions of decidual macrophages correlate with adverse pregnancyoutcomes, such as spontaneous abortion and preeclampsia. Previously, decidual macrophages were often thought to be a singlepopulation. In the present study, we identified three decidual macrophage subsets, CCR2−CD11cLO (CD11clow, ~80%), CCR2−CD11cHI (CD11chigh, ~5%), and CCR2+CD11cHI (CD11chigh, 10–15%), during the first trimester of human pregnancy by flowcytometry analysis. CCR2−CD11cLO macrophages are widely distributed in the decidua, while CCR2−CD11cHI and CCR2+CD11cHImacrophages are primarily detected close to extravillous trophoblast cells according to immunofluorescence staining. According toRNA sequencing bioinformatics analysis and in vitro functional studies, these three subsets of macrophages have differentphagocytic capacities. CCR2+CD11cHI macrophages have pro-inflammatory characteristics, while the CCR2−CD11cHI population issuggested to be anti-oxidative and anti-inflammatory due to its high expression of critical heme metabolism-related genes,suggesting that these two subsets of macrophages maintain an inflammatory balance at the leading edge of trophoblast invasionto facilitate the clearance of pathogen infection as well as maintain the homeostasis of the maternal-fetal interface. The presentstudy physiologically identifies three decidual macrophage subsets. Further clarification of the functions of these subsets willimprove our understanding of maternal-fetal crosstalk in the maintenance of a healthy pregnancy.

Microstructure of the matrix directly influences the performance and the application of metal matrix composites. By using vacuum casting-infiltration method to manufacture casting tungsten carbide particle reinforced composite, the addition of Ni can alter the microstructure of the matrix of composite. High carbon chromium steel was chosen as the substrate. The casting process was achieved at 1580 ℃ with vacuum degree of 0.072-0.078 MPa. Padding of the molten steel in each part of the preform was different, and the solidification of each part of the composite was different, too. Microstructure of the matrix was various in different parts of the composite. The Ni addition had enlarged the austenite zone in matrix, which would improve the corrosion resistance of the composite. The phase identification of the composite was performed by X-ray diffraction technique. The result showed that Fe3W3C was the primary precipitated carbide and its composition had a direct link with the decomposition of the casting tungsten carbide particles. The hardness of the matrix mainly depended on the reinforced carbide, i.e. Fe3W3C.

A novel TiNi/AlSi composite with high compressive strength and high damping capacity was obtained by infiltrating Al-12%Si alloy into porous TiNi *** had been found that the high compressive strength (440 MPa) of TiNi/AlSi composite is due to the increase of effective carrying area after infiltrating Al-12%Si alloy,while the high damping capacity is contributed to TiNi carcass,Al-12%Si filling material and micro- slipping at the interface.

The unfolding of neutron spectra from the pulse height distribution measured by a BC501A scintillation detector is accomplished by the application of artificial neural networks (ANN). A simple linear neural network without biases and hidden layers is adopted. A set of monoenergetic detector response functions in the energy range from 0.25 MeV to 16 MeV with an energy interval of 0.25 MeV are generated by the Monte Carlo code O5S in the training phase of the unfolding process. The capability of ANN was demonstrated successfully using the Monte Carlo data itself and experimental data obtained from the Am-Be neutron source and D-T neutron source.

This paper is concerned with the non-fragile H∞ filter design problem for uncertain discrete-time Takagi-Sugeno （T-S） fuzzy systems with time delay. To begin with, the T-S fuzzy system is transformed to an equivalent switching fuzzy system. Then, based on the piecewise Lyapunov function and matrix decoupling technique, a new delay-dependent non-fragile H∞ filtering method is proposed for the switching fuzzy system. The proposed condition is less conservative than the previous results. Since only a set of LMIs is involved, the filter parameters can be solved directly. Finally, a design example is provided to illustrate the validity of the proposed method.
