推导了以顺波、逆波为状态向量的应力波传播方程和杆形部件的作用力、速度传播的特征矩阵；
Stress wave propagation equations that incident wave and reflection wave are condition vectors are derived from three discrete forms as well as the characteristic matrix of the force and the velocity.
此算法自动找出NURBS曲线需要修改的那一点，局部修改控制多边形，使生成的新曲线更加光顺。
The algorithm automatically identifies the point at which the NURBS curve has to be faired. Modifying locally the control polygon, the algorithm yields a NURBS curve with improved fairness.
鉴于这种情况，我们先使用低通滤波对轮廓曲线作光顺处理，随后再采用基于面积误差的多边形逼近法对曲线作逼近处理。
And they are often distorted. First, a low passed filter is used to smooth the contour. And a polygon approximating method based on area error is used to approximate the contour.
