说明：  一组使用纯CSS3制作的预加载动画特效。这组CSS3预加载动画特效共有(The hor effect of this group of pictures has 16 special effects. The effect also supports the rap version.)

verigy v50测试程序

说明：  这是一个包括程序和文档在内的高斯低通滤波器的设计与实现过程，对于滤波器初学者很有用。(This is a prediction program that can realize Arima. The program is labeled and easy to understand.)

C++编写的一个猜字游戏程序，适合有一定C++基础的新手(C++ written a guessing game program, for a certain person based on C++)

产生一组均值为1，方差为4的正态分布随机序列（1000个样本），估计该序列的均值与方差(A set of normal distribution random sequences (1000 samples) with mean value of 1 and variance of 4 is generated, and the mean and variance of the sequence are estimated)

说明：  采用神经网络进行图像分类，分类方法简单，但是效果略差。(Using neural network for image classification, the classification method is simple, but the effect is slightly poor.)

一款强大的图表框架，支持大数据图形显示（通过图片方式）(DynamicDataDisplay-example-master)

说明：  lms滤波，可以用于去噪。在标准sin的信号基础上加入高频噪声，均匀白噪声和高斯白噪声，再采用lms滤波，可以得到预期波形(LMS filtering can be used for denoising. The expected waveform can be obtained by adding high frequency noise, uniform white noise and Gaussian white noise on the basis of standard sin signal and using LMS filter.)

说明：  针对已知多频率正弦信号的频谱，设计相应的FIR滤波器(凯塞窗函数法设计低通,高通，带通滤波器，分别提取信号并绘制频域和时域曲线)按要求进行滤波。 根据已知滤波器的性能指标设计IIR数字滤波器(双线性变换法设计巴特沃斯低通IIR数字滤波器)，并对心电图信号进行滤波处理；(For known more frequency sinusoidal signal spectrum, to design the corresponding FIR filter (Kaiser window function method of designing low-pass, high-pass, band-pass filter, respectively, to extract the signal curve) and draw the frequency domain and time domain filtering according to the known filter in accordance with requirements of performance index design of IIR digital filter (bilinear transformation method to design butterworth low-pass IIR digital filter), and to filter the ecg signal)
