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

根据高斯光束的特性，在matlab中作出束腰半径为0.5mm的高斯光束在束腰处的三维光强分布图。(According to the characteristics of the Gauss beam, the three-dimensional intensity distribution of the Gauss beam with the waist radius of 0.5mm at the waist is made in MATLAB.)

通过拉格朗日方程模拟仿真双摆系统的运动过程，并生成poincare映射图(The motion process of double pendulum system is simulated by Lagrange equation, and Poincare map is generated.)

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.)

一维和二维Airy光场的输出，以及不同距离的传输模拟。自加速过程模拟(Simulation of Airy Beam)

平面波或锥形波照射任意粗糙面，用基尔霍夫近似方法的散射计算(Kirchhoff scattering rough surface)

说明：  导入matlab后添加另一个gearsolve函数，使用ode45进行t为0.001：0.001：1000和刚度ky数组，即可获得齿轮组的全自由度运动图像(After importing MATLAB, add another gearsolve function, use ode45 to do t = 0.001:0.001:1000 and stiffness KY array, then the full degree of freedom motion image of gear set can be obtained)

说明：  基于晶体塑性自洽理论 vpsc 模拟多晶体塑性变形的织构演化(Texture evolution of polycrystalline plastic deformation simulated by vpsc based on crystal plasticity self consistent theory)

重磁异常正演方法，是在给定地质体的形状大小、空间位置及物性参数的条件下，求它外部空间任意点上的物理场值。(The forward method of gravity and magnetic anomaly is to calculate the physical field value at any point in the outer space of a given geological body under the condition of its shape, size, space position and physical parameters.)

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.)
