对于大量照片求取通道内气泡长度和频率生成信息，每张都求取，计算速度较慢(For a lot of photos to strike a channel length and frequency of the bubble generation information, each have to strike, the calculation speed is slow)

When doing black and white figures with several curves, it is sometimes difficult to uniquely identify each curve, since the number of different line styles is quite limited.

异步电机的无速度传感器的矢量控制。matlab程序。有详细的说明文件。用于交流学习用。(Induction motor speed sensorless vector control. matlab program. Detailed documentation. Used for the exchange of learning.)

说明：  灰色理论的应用，是一种成语实现，用于预测数据。(Application of Grey theory is a kind of idiom to achieve, to predict the data.)

述是经典MUSIC算法的基本原理，许多限制是可以放宽或取消的。首先，关于均匀线阵的限制不是必须的，实际中可采用几乎是任意形状的阵列形式，只要满足在个独立信号源的条件下，矩阵具有个线性无关的列就可以了。其次，天线阵元在观测平面内无方向性这一点也不是必要的，而且还可以考虑三维空间的DOA估计问题，即不仅估计信号的方位角，还要估计它的俯仰角，当然MUSIC算法还用于频率、方位和俯仰的联合估计。(Above is the basic principle of the classical MUSIC algorithm, a number of restrictions can be relaxed or canceled. First, restrictions on ULA is not necessary, the actual form of an array can be almost any shape, as long as the signal source in the independent condition matrix has linearly independent columns on it. Second, the antenna elements in a plane non-directional observation it is not necessary, but could also be considered DOA estimation of three-dimensional space, that is not only estimated azimuth signals, but also to estimate its pitch angle, of course, also MUSIC algorithm joint estimation for the frequency, the azimuth and elevation.)

说明：  数字图像修复算法的评价标准也是从两个方面进行评价的，一个是修 复算法的效率，一个是修复后图像质量。修复算法的效率主要就是看修复 图像所用的时间，可以用时间就行量化。而图像质量很难从量上唯一的进 行评价，目前图像修复质量还没有统一的评价标准，从实际应用出发，修 复后图像质量的好坏大多数是从以下两个方面就行评价，修复后图像给人 主观上的“满意度”和客观上图像的cnr、enl、epi、psnr、snr来评判。(The evaluation criteria of digital image restoration algorithms are also evaluated from two aspects, one is repair. One of the efficiency of complex algorithm is the image quality after restoration. The efficiency of the repair algorithm depends mainly on the repair. The time spent on the image can be quantified in terms of time. But image quality is difficult to improve quantitatively only. At present, there is no uniform evaluation criterion for image restoration quality. Starting from practical application, repair The quality of restored images is mostly evaluated from the following two aspects, and the restored images are given to people. Subjective "satisfaction" and objective image cnr, enl, epi, psnr, SNR to judge.)
