说明：  5种不同PML的效果对比，基于MATLAB进行分析，通过修改可以改为自己的PML代码(Effect comparison of five different PML)

说明：  根据地层参数（速度、密度、厚度），设计相应子波，合成地震记录(According to the formation parameters (velocity, density, thickness), the corresponding wavelet is designed to synthesize the seismic record)

说明：  matlab编程利用hess simth面元法(边界元法)计算球体及椭球体附加质量(Matlab programming uses hess_simth surface element method (boundary element method) to calculate the additional mass of spheres and ellipsoids)

说明：  For the model of indoor air distribution tuyere proposed by Professor Zhang Tengfei, this paper is UDF code for fluent simulation.

求解椭圆型方程生成二维翼型网格，并采用逐线松弛迭代技术求解了二维翼型绕流，这是CFD计算中的典型例子，是cfd初学者的很好的学习例子。(Solving elliptic equations, generating two-dimensional airfoil mesh, and using line relaxation iterative technique to solve the two-dimensional airfoil flow, which is a typical example of CFD calculation, a good example for new CFD learner.)

平面波从石英玻璃入射到空气中的P、S分量的反射波相位和透射波相位随入射角度的变化(The phase of the reflected wave and the phase of the transmitted wave of the plane wave from the quartz glass to the air in P and S vary with the angle of incidence.)

说明：  超短脉冲是谐振腔中增益与损耗达到平衡、色散与非线性达到平衡时所产生的。啁啾型脉冲在光纤中传播，因色散作用及各种非线性作用谱线被展宽。(Ultra-short pulses are generated when the gain and loss of the cavity are balanced, and the dispersion and nonlinearity are balanced. Chirped pulses propagate in optical fibers, and their spectral lines are broadened due to dispersion and various non-linear effects.)

说明：  通过2SeaColor模型，对遥感影像进行水质参数反演(Through the 2seacolor model, the water quality parameters of remote sensing images are inversed)

可以读取gmesh软件产生的网格数据，读取.msh(Can read grid data generated by gmesh software, read .msh)

高斯扩散模式适用于均一的大气条件，以及地面开阔平坦的地区，点源的扩散模式。排放大量污染物的烟囱、放散管、通风口等，虽然其大小不一，但是只要不是讨论烟囱底部很近距离的污染问题，均可视其为点源。(The Gauss diffusion model is applied to homogeneous atmospheric conditions, as well as to ground open flat regions, and to point source diffusion patterns. Chimneys, pipes, vents, etc. that emit large quantities of pollutants, although they vary in size, can be regarded as point sources as long as they do not discuss the pollution problems near the bottom of the chimney.)
