摘要
本文利用一维自动机模型研究了声格固体模型插值算法中粒子速度取不同值时对结果的精度及稳定性的影响。结果表明 ,只有当被插值点位于各插值节点的中心位置附近时 ,所得结果才具有较高的精度和稳定性。因此当插值节点数n≥ 4时 ,对于某些速度值 ,插值得到的结果是不稳定的。
In this paper, the authors have dealt with the stability of the PLSI method at various particle speeds. The results show that the method is stable only when the interpolated point is near the middle of interpolating nodes. In addition, several solutions to this condition are discussed.
