超视距多目标攻击逻辑决策和空战态势评估是超视距空战研究的主要方面,但对空战战术影响较大的战机飞行轨迹和飞行参数的研究较少.通过对超视距空战和视距内空战的比较,分析了超视距空战的空战过程.根据超视距空战迎头攻击战术的特点,建立了相应飞行轨迹的数学模型,并求解了载机速度、载机发射导弹速度、转弯速度、载机转弯半径、目标机速度、载机飞行时间、转弯时间和导弹飞行时间之间的关系.通过仿真分析了飞行参数对飞行轨迹的影响,并根据载机性能约束条件,求解了飞行参数的最优解.仿真结果表明,飞行轨迹模型和最优飞行参数设计的合理性和可信性,可为超视距空战战术、战法决策等作战应用提供重要参考. 相似文献

In order to consider the viscous effect,the introduction of a parametric dissipation and new results are realized by applying the new formulation combining and dynamic conditions over the free-surface with viscous terms. The dispersion equation is then modified by assuming an additional term in the boundary condition at the free-surface and wave-number becomes complex number with a small imaginary part which ensures the decay of wave amplitudes. The comparisons of numerical results and model test measurement on wave elevation at the moon-pool center is obtained both for the peak period and for the amplitude at resonance by choosing an appropriated dissipation coefficient. The results show that the introduce dissipation is not only effective but also reliable to provide realistic predictions. 相似文献

A proteomics-based approach has been used to identify proteins that commonly elicit a humoral immune response in nasopharyngeal carcinoma (NPC). Sera from 19 newly diagnosed NPC patients and 19 healthy individuals were analyzed for IgG autoantibodies against NPC proteins resolved by 2-DE. Protein spots that exhibited selective reactivity with sera from NPC patients were identified by MS. Among nine identified proteins, cytokeratin 19 (CK19), Erb3 binding protein (EBP1), and Rho GDP dissociation inhibitor-beta (Rho-GDI-2) induced autoantibodies in more than 36.8% of NPC patients but not in healthy individuals. Furthermore, Western blot analysis and immunohistochemical staining were performed to determine the expression and localization of CK19, EBP1, and Rho-GDI-2 in NPC and normal nasopharyngeal mucosal tissues. Up-regulated CK19 and EBP1, but not Rho-GDI-2, were observed in NPC vs. normal tissue. Subcellular localization of the three proteins in NPC tissue was same as that in the normal tissue. Thus, overexpression of CK19 and EBP1 may be one of the mechanisms for their autoantibody development in NPC. To validate the findings of a proteomic analysis, occurrence of autoantibodies against these three proteins was detected by immunoprecipitation and Western blot analysis in additional 30 NPC patients, 23 other types of cancer patients and 20 healthy individuals. Results showed that frequency of autoantibodies against CK19, EBP1 and Rho-GDI-2 in NPC patients was significantly higher than that in other types of cancer patients and healthy individuals. We conclude that CK19, EBP1 and Rho-GDI-2 may have utility in NPC screening and diagnosis. 相似文献

This paper is concerned with the guaranteed cost control for continuous-time singular Markovian jump systems with time-varying delay. Without using the free weighting matrices method, a delay-range-dependent condition is derived in terms of strict linear matrix inequality (LMI), which guarantees that the singular system is regular, impulse free and mean-square exponentially stable with an H(∞) performance. Based on this, the existence condition of the guaranteed cost state feedback controller is proposed. A numerical example is given to illustrate the effectiveness and less conservatism of the proposed design method. 相似文献

近日,欧盟发布的新法规使公众能够更好地获得环境信息,同时对其所有的成员国都具有约束力。新法规能够增强欧盟现行有关环境法规的作用,并与1998年在奥尔胡斯公约上提出的环境信息要求保持一致。根据这项公约,公众有权获得所需的环境信息并参与制定相关的环境法规,当出现违反相关环境法规的行为时,公众可以依据此项公约提出诉讼。 相似文献
