说明：  灰色预测模型，对未来数据进行预测，同时还有误差检测(GM(1,1),Grey prediction model, which can forecast future data and detect errors at the same time)

有限元计算开源库，可以用于计算动力、静力、磁场等等方面的计算(Finite element calculation open source library)

六轴工业机器人的逆运动学,采用VC++进行编程自动求解(inverse of 6-dof industrial robot)

BICG算法，是Krylov子空间的迭代方法之一(The BICG algorithm is one of the Krylov subspace iteration method)

波束域 MUSIC 算法跟经典MUSIC 算法相比，具有更小的分辨信噪比门限(Beamspace MUSIC algorithm compared to the classic MUSIC algorithm, with smaller resolution and signal to noise ratio limit)

说明：  ADAM （Adaptive Moment Estimation）是另外一种自适应学习率算法，它结合动量梯度 下降法，在不同参数方向上采用不同学习率，保留前几次迭代的梯度，能够很好 的适应于稀疏数据。(ADAM (Adaptive Moment Estimation) is another adaptive learning rate algorithm, which combines momentum gradient. The descent method, which uses different learning rates in different parameter directions and retains the gradients of previous iterations, is very good. It is suitable for sparse data.)

说明：  相场基础书籍的配套计算代码，对于学习相场法的基础同学来说极其有用(The supporting calculation code of the phase field basic book is extremely useful for the students who are studying the basic method of the phase field method.)

QR分解法是目前求一般矩阵全部特征值的最有效并广泛应用的方法，一般矩阵先经过正交相似变化成为Hessenberg矩阵，然后再应用QR方法求特征值和特征向量。它是将矩阵分解成一个正规正交矩阵Q与上三角形矩阵R，所以称为QR分解法,(QR decomposition )

说明：  umat公式详细介绍，我也不知道够20字了mei(the introduction of umat in abaqus)

说明：  通过MATLAB编程模拟理想弹塑性应力应变曲线(Simulating the stress-strain curve for perfect plasticity by MATLAB coding.)
