Based on the background of the " ten - five " technology project ， we introduced the last development of helicopter ' s landing devices and optolelectronic guiding equipments . this paper describes the study of beacons - based algorithms of ccd tv sensor , discusses the imaging processing , design the infrared vision - enhanced system 本论文以国防科技十五项目为背景，概要地介绍了国内外直升机着降和光电引导装置的最新发展状况,对机载ccd电视传感器的信标测量算法进行系统分析和深入研究，对图像处理进行了讨论，提出了具有创新意义的机载红外ccd视景增强系统设计。
The thesis consists of four sections : the first section mainly introduces briefly the basic of brain science ; the second section focuses on the research of brain science about learning ; the third section demonstrates the necessity of putting brain science into the teaching field . there are two reasons : one is to endow teaching with new meanings ; the other is to provide the teaching reform with new perspective and prove the teaching practices and reflect on them ; the fourth section makes an attempt to discuss the teaching practices , that is , brain - based teaching in the perspective of brain science 本文分四部分进行论述，第一部分，概要地介绍了脑科学的基本情况；第二部分，介绍脑科学对学习的研究；第三部分，论证了脑科学步入我国教学领域的必要性，理由一方面是脑科学对教学的意义，主要体现在对教学改革提供新视角和对教学实践的佐证和反思；另一方面是从脑科学视角审视教学，赋予教学以新的意义和内涵；第四部分，尝试性地论述了脑科学视野中的教学实践，即建立在脑科学基础上的教学实践。
According to the different time of continuing disclosure , continuing disclosure system is divided into periodic disclosure system and temporary disclosure system . on the basis of essential elaboration and analysis the thesis put forward some definite proposals on the submission time of the periodic report and materiality standards of the temporary report 本文对我国和其他各国关于这两种制度的规定进行了概要地阐述和分析，并在此基础上对我国定期报告中的提交期限问题和临时报告中的重大性标准问题提出了一些具体的完善建议。
This thesis present the systematic studies on firing accuracy and firing accuracy tactical & technical requirement reasoning for gunnery system . the main contents of the paper are as follows . ( 1 ) definitions and probability distribution expressions for error of fire , error of firing data and error of dispersion are given summarily . methods to compose error of initial firing data and error of dispersion are discussed 本文对远程炮武器系统射击精度及射击精度战术技术指标论证等方面问题进行了深入、系统的分析研究，本文研究工作的主要内容有： ( 1 )概要地讨论了射击误差、诸元误差、散布误差的定义及其概率分布，诸元误差、散布误差及射击误差的合成，分析了射击精度的各种表示法，阐述了火炮武器系统准确度、密集度和首发命中概率的估算方法。
