等间距线性阵列，阵元间距d= λ /2，等幅加权，目标方位φr = 0°，无噪声。 分别仿真计算阵元数M=8 、16时的阵列方向图，定性分析产生的原因。（可通过3dB波束宽度计算公式说明） (Equally spaced linear array, the array element spacing d = λ/2, equal amplitude weighted target azimuth φr = 0, no noise. , Respectively, the number of array elements M = 8 and 16 when the array pattern, qualitative analysis to produce simulation. (Available by 3dB beamwidth formula noted))

机器人运动学和动力学模型，六自由度的，界面设计以及轨迹规划等功能(Robot kinematics and dynamics models, six degrees of freedom, interface design, and trajectory planning, etc.)

matlab实验的一个部分，比较简单和实用，有指导意义。(Matlab a part of the experiment, is simple and practical, has significance.)

子波分析是一种日益获得广泛应用的信号处理新技 术, 具有良好的时-频局部化特性, 尤其适用于时变及非平 稳信号。本文简述了子波函数与子波展开的基本概念, 利用 展缩子波和调和子波将信号及信号均方值进行时-频两维 分布。最后采用了三种子波分析方法对轴承故障进行诊断, 即使对现有各种方法尚难以诊断的滚动体故障, 也能获得 满意的结果, 说明子波分析的确为机械故障诊断提供了强 有力的分析手段。(Wavelet a nalysis, as a new technique of signal processing , possesses ex cellent characteristic of time-frequency localization and is suitable for analyzing the time-var ying or transient signals. In this paper , the basic concepts of wavelet function and wavelet expansion are briefly introduced. The time frequency distribution of signal and its energy are obtained by decomposition via dilating wavelet and harmanic wavelet. )
