平截头圆锥体划分为三个辐射面—火焰侧面、火焰顶面及火焰底面。基于微元思想进一步对喷射火辐射表面进行了合理的离散化，对喷射火平截头圆锥体的视角因子进行研究。 (To simplify the view factor calculation process, the cone frustum with a certain angle is transformed into the vertical cone frustum and the transform parameter formulas are achieved.)

两个相控阵天线时域波的传播不同阶段主要表现不同(In this code, the time domain wave propagation for two phased array antennas at different phase differences are shown. Thanks to the constructive and destructive interferences, the main beam of the wave is steered towards angle of interest. This code is used to generate the following animation: )

quasi discrete cosine transform

程序为地震勘探资料处理方法中的数值模型模拟正演，方法为射线追踪(The program forward numerical model for seismic exploration data processing method in the simulation, for ray tracing method)

三维时域有限差分程序，cpml吸收边界，介质表面采用网格均分技术(Three-dimensional finite-difference time-domain algorithm, CPML absorbing boundary, sharing media surface using grid technology)

利用自相关法，计算基音周期，结果给出对应的时间值坐标。(The pitch period is calculated by the autocorrelation method, and the corresponding time value coordinate is given.)

该功能用matlab实现的几个界面，可供新手们参考学习下哈(This feature is implemented with a few matlab interface for novices to learn under reference Ha)

多进制PSK调制的matlab实现程序，能过实现M进制的psk调制(Ary PSK modulation matlab implementation program that can achieve over the psk M-ary modulation)
