利用matlab写成的窄带噪声发生，高斯白噪声的生成程序，构成不同频率的调制信号。( Using matlab written narrowband noise occurs, Gaussian white noise generator, Constituting the modulated signals of different frequencies.)

LBM方法2维9速度模型，求解管道圆柱扰流问题。(Channel flow past a cylinderical obstacle(D2Q9, LBM method).)

the network lifetime based on a new Energy-Aware Objective Function used to design a Routing Protocol for Low-Power and Lossy Networks. The proposed Objective Function uses the Expected Transmission Count Metric and the Remaining Energy on each sensor node to compute the best paths to route data packets across the network.So EAOF prolongs the network lifetime and reduces the need for human intervention on battery changing, thereby enhancing the system wearability and reducing operational costs.

根据选择的txt文件内的内容，让matlab自动从任意excel文件里提取相应内容。涉及快速读写大型excel文件、matlab正则表达式。(Based on the contents of the selected txt file, matlab automatically extracted from any excel file. Involving fast reading and writing large excel files、matlab regular expressions.)
