随机信号分析理论如何在实践中应用；随机信号的检测及分析方法；强噪声背景下微弱信号的提取又是信号检测的难点，其目的就是消除噪声，将有用的信号从强噪声背景中提取出来(How random signal analysis theory applied in practice random signal detection and analysis methods strong noise background of weak signal extraction and signal detection is difficult, its purpose is to eliminate the noise, the useful signal from strong background noise extracted)

水利工程马斯京根法洪水演算程序，模块化编程，内含3个关键函数，x、k率定方法采用直接率定方法，速度更快。(Mas root method for flood routing procedures, modular programming, it contains three key function, x, k rate method using direct rate, faster.)

有源低通巴特沃斯滤波器设计根据给定的参数值设计有源滤波器(Active low-pass Butterworth filter design parameters according to the given active filter design)

分数阶差值，分数倍上采样，DUC模块中应用，在TVB2系统中仿真使用。(Fractional difference scores sampling times, DUC module applications, simulation using TVB2 system.)

这个文档包含四种不同的功能求解非线性方程组。包括牛顿 - 拉夫逊，定点，正割，二分法方法。这项工作是我的课程的一部分，在数值计算的本科课程。它包括时序和表的打印输出进行分析和比较。有很多的观察，你可以：例如，对于一个特定的公式，一种方法可能运行的迭代次数最少，而另一个将运行更多的迭代，但计算速度最快的。(This document contains four different functions for solving nonlinear equations. Including Newton- Raphson, fixed, Secant, bisection method. This work is a part of my course in numerical undergraduate courses. It includes the timing and tables to analyze and compare the printout. There are a lot of observation, you can: For example, a specific formula, a method may be running a minimum number of iterations, while the other will run more iterations, but the calculation is the fastest.)

语音文件中有单频噪声，设计高频滤波器和低频滤波器进行语音滤波(Audio files with a single frequency noise, high frequency filters and low-frequency filter design for voice filtering)

Fibonacci数列，已知一个Fibonacci数，能求出它的N值(Where Fibonacci sequence, a number of known where Fibonacci, can find its N)
