说明：  关于解微分方程的matlab小程序，适合本科生学习使用。(MATLAB in Physics is a four lecture series in MATLAB that is offered to first year physics undergraduate students. This lecture shows how to use MATLAB to simulate physical systems using a range of methods. Projectile motion is analysed using the Symbolic Math Toolbox, then more complicated chaotic systems are simulated using the MATLAB ODE solvers. Some advanced programming techniques such as Object Oriented Programming (OOP) and Graphical User Interface (GUI) programming are briefly covered. The aim of this lecture series is to introduce students to computational methods in MATLAB to solve problems arising in physics that cannot be solved analytically. No prior knowledge of MATLAB is required. Themes of data analysis, visualization, modelling and programming are explored throughout these lectures. )

声光技术在雷达动目标模拟中的应用， 由于受到延迟时间固定不变或只能离散变化的限制,许多雷达目标模拟器不能模拟连续运动目标的变化。为此,设计了一种新型的声光延迟系统,并对该系统的性能作了分析。与其它延迟系统相比,本系统的优点在于延迟时间可连续变化,延迟总时间可满足信号处理的要求。因此,它可以方便地应用于运动雷达目标模拟和其它信号的处理。 (Sound and light technology in radar moving target simulation, due to the limit of the delay time constant or only discrete changes, many radar target simulator can not simulate changes in the continuous moving target. To this end, the design of a novel acousto-optical delay system, and the performance of the system analyzed. Compared with the other delay system, the advantage of this system is that the delay time can be continuously changes to delay the total time can satisfy the requirements of the signal processing. Therefore, it can be easily applied to the sports radar target simulation, and other signal processing.)
