| 4. | With the fast - developing aeronautical technology and fast - changing world political environment , the super - powers have posed more critical requirements to military aircrafts . these requirements include expanded flight envelop , higher agility and reliability 随着航空科技的发展和世界局势的变化,世界各国对新一代军用战机的性能提出了更高的要求:具有更宽广的飞行包线;更高的灵活性、机动性、可操作性、可靠性和可生存性。 |
| 5. | Following the developing of the aeronautical technology , higher request was brought forward to deployable antenna on satellites from every relative field . a lot of structural concept for deployable antenna was given out by aeronautic scholar . astromesh deployable antenna is one of them , which has most potential for space application 随着宇航科技的发展,各相关学科对空间可展天线提出了更高的要求,主要体现在大口径、高精度两方面,为此各国学者提出了形式众多的空间可展天线结构概念,环形桁架可展天线是其中最具潜力的结构形式之一,是本文研究的一个重要方面。 |
| 6. | Abstract : this paper analyses the statistical information fed back from the investigations on niat graduates . constructive suggestions are made after studying of the basic situation of 1990 - 1999 year ' s graduates , which are helpful to the educational reform of nanchang institute of aeronautical technology ( niat ) 文摘:本文根据南昌航空工业学院第四次毕业生跟踪调查反馈的信息,对1990 ? 1999年十届毕业生的基本素质状况进行了分析和研究,对进一步抓好学院教育教学改革工作提出了建设性的意见。 |
| 7. | The new algorithm starts from an initial estimate which is based on the hough transform , and a rectangular window is centered using the current line approximation , and a new line estimation is generated by making a total least squares fit through the pixels contained within the window . this is repeated until convergence is reached . lastly , we have suggested a new technique which may recover the motion and structure parameters of a moving object by using of 21 optical flow lines based on the optical flow fields of the feature line this thesis is the project supported by aeronautical foundation science ( no . 99f53065 ) and research center of measuring and testing technologies , and control engineering in nanchang institute of aeronautical technology ( no . 2001 - 15 ) 算法的思路是:首先,在小区域内运用霍夫变换确定直线的初始值;其次,以直线的初始值所对应的直线为中心线,建立一个矩形框;最后,利用矩形框内所包含的边缘点数据不断地迭代直至收敛,从而达到进一步修正直线的坐标参数;本文基于特征直线的光流场,即线流场,建立了一种利用21条光流线确定空间三维物体旋转运动参数、平移运动参数以及对应的空间直线坐标的线性算法。 |
