说明：  魔术轮胎公式，车辆动力学中常用的关于轮胎的建模(magic tire,used in vehicle model.)

稳健波束形成中的mvdr（最小方差无畸变失真响应）算法(robust adaptive bearforming mvdr)

节点度是指和该节点相关联的边的条数，又称关联度。 特别地，对于有向图， 节点的入度 是指进入该节点的边的条数; 节点的出度是指从该节点出发的边的条数。(Node degree refers to the number of edges associated with the node, also known as the degree of association. In particular, for a directed graph, The ingress of a node is the number of edges entering the node; The out-degree of a node is the number of edges that start from that node.)

汽车动力模型，包括：整车模型，发动机模型，ECU模型，变速器模型等。(Basic example : Gasoline vehicle)

说明：  新的屈服准则ABAQUS子程序UMAT，含有多种较新的准侧，能很好运用(The new yield criterion ABAQUS subroutine UMAT contains a variety of newer standards and can be used very well.)

说明：  三相桥式全控整流电路仿真，使用晶闸管进行三相桥式全控整流电路仿真。(Three-Phase Full-Bridge Controlled Rectifier)

使用zernike多项式进行光学像差的拟合，从而进行光学镜面像差的分析，有助于提高光学系统的加工精度。(The Zernike polynomial is used to fit the optical aberration, and the analysis of optical mirror aberration is helpful to improve the machining precision of the optical system.)

说明：  利用TOA与最小二乘法直接求解（具有独立创新性），TDOA是利用拉格朗日法求解，而且里面的定位图解做得特别好，分别有一点定位，多点定位的的三维视觉图。(TOA is directly solved by least squares method(Innovativeness),TDOA is solved by Lagrange's method.)

very helpful for those who have initiated research

说明：  umat基础知识教学，适合刚接触UMAT的新手做参考(UMAT basic knowledge teaching, suitable for beginners)
