这种证明根据的是胁变能量的非负性。 - A propbr data structure is used to assist grid generation for different geometric dimensions . a concept of entropy in broad sense is proposed for convective - diffusive problems in chapter 7 . it is proved that there is an intrinsic relationship between the stability of the numerical schemes of the convective - - diffusive differential equations and the non - negative property of the entropy generation caused by the effective diffusion
第七章提出了对流扩散问题中的广义熵概念,研究了扩散熵产非负性特征与数值格式稳定性的内在联系,分析证明了扩散熵产非负定性及统计非负定性的稳定性准则,探讨了稳定性与仿真性之间的矛盾与联系。 - By the means of optimization methods , degree reduction of rational bezier curves is changed to a optimization problem so that both weights and vertices are consider respectively . using programming method and genetic algorithms , a new method on rational bezier curves is presented
第四从最优化的思想出发,把有理b zier曲线的降阶转化为求最优化问题,这样也使得权因子和控制顶点被分开考虑,以保证权因子的非负性;同时结合智能计算中的仿生学方法和程序设计方法,给出了有理b zier曲线降阶的一种新方法。
