IE3D软件的很多教程，很好很强大！很珍贵的啊(IE3D software, many of tutorials, very good very strong! Ah very valuable)

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.)

最优化问题的相关算法，很全，有做些简单的修改就行。(Optimization of correlation algorithm, it is full, there are some simple changes to the line.)

模拟2个独立窄带信号入射到均匀线阵上，信号间互不相关，与噪声相互独立，噪声为理想高斯白噪声，阵列的阵元数为10，快拍数为200。阵元间距为入射信号波长的1／2，信噪比为20dB，信号入射角度差分别为5°，10°，20°。(Simulate two independent narrowband signals incident on the ULA, among signal unrelated, independent noise, the noise is ideal Gaussian white noise, the number of array elements of the array is 10, the number of snapshots to 200. Element spacing is 1/2 of the wavelength of the incident signal, SNR is 20dB, the signal difference between the angle of incidence was 5 °, 10 °, 20 °.)
