搜索型随机格斗命中次数的分布与毁伤概率 总被引:3,自引:0,他引:3
本文研究了搜索型随机格斗模型,采用在时间[0,t]内射击命中目标次数的概率分布与毁伤概率指标来评定射击效果。文章对射击时间间隔随机变量服从的分布采用两种假设t指数分布与一般分布.对指数分布的假设,文章导出的结果比较完善;对一般分布的假设,文章导出了计算射击命中次数概率分布的计算公式。 相似文献

基于线导+尾流自导鱼雷的弹道特点和末端尾流进入角的使用限制,选用Runge-Kutta方法,得出线导+尾流自导鱼雷在不同尾流进入角和不同射距时的弹道轨迹,进而分析并解算出线导+尾流自导鱼雷有效射击可行域.方法对自导鱼雷有效射击可行域解算方法进行了较大改进,能更好地满足线导+尾流自导鱼雷作战使用时射击阵位点选择需求. 相似文献

针对装甲兵射击目标选择的特点,建立射击目标选择的数学模型,结合层次分析法,运用效用信息熵理论,通过实例不仅给出了射击目标的合理排序,还得到了影响射击目标选择的主、次要因素,可为装甲兵作战指挥自动化系统辅助决策提供一种新的方法. 相似文献

毛主席教导我们:“战争的基本原则是保存自己消灭敌人”.在近代战争里,炮兵射击很讲究“首发命中”,为此,既快又准地算出我方炮位与目标的距离非常重要. 我们到××部队学军,炮连一位同志提出一个测距计算问题.战争时,炮兵在战场上测量,往往要求在现场立即由测量数据推算出所要的结果.因此,计算工作需在野外而不是在房间进行、需要快速而不可丝毫怠慢.过去,如果要求结果很准确,就必须化费较多 相似文献

As early as in 1990, Professor Sun Yongsheng, suggested his students at Beijing Normal University to consider research problems on the unit sphere. Under his guidance and encouragement his students started the research on spherical harmonic analysis and approximation. In this paper, we incompletely introduce the main achievements in this area obtained by our group and relative researchers during recent 5 years (2001-2005). The main topics are: convergence of Cesaro summability, a.e. and strong summability of Fourier-Laplace series; smoothness and K-functionals; Kolmogorov and linear widths. 相似文献

Let P(z)=∑↓j=0↑n ajx^j be a polynomial of degree n. In this paper we prove a more general result which interalia improves upon the bounds of a class of polynomials. We also prove a result which includes some extensions and generalizations of Enestrǒm-Kakeya theorem. 相似文献

In applications it is useful to compute the local average empirical statistics on u. A very simple relation exists when of a function f(u) of an input u from the local averages are given by a Haar approximation. The question is to know if it holds for higher order approximation methods. To do so, it is necessary to use approximate product operators defined over linear approximation spaces. These products are characterized by a Strang and Fix like condition. An explicit construction of these product operators is exhibited for piecewise polynomial functions, using Hermite interpolation. The averaging relation which holds for the Haar approximation is then recovered when the product is defined by a two point Hermite interpolation. 相似文献

Given the Laplace transform F(s) of a function f(t), we develop a new algorithm to find an approximation to f(t) by the use of the classical Jacobi polynomials. The main contribution of our work is the development of a new and very effective method to determine the coefficients in the finite series expansion that approximation f(t) in terms of Jacobi polynomials. Some numerical examples are illustrated. 相似文献
