差分格式
Examples
- Secondly , we present the principle of the algorithm , including its three key factors : the difference format , the stability condition and the absorbing boundary condition ( abc )
第二章我们介绍了fdtd算法的基本原理以及算法的三大要素：差分格式、解的稳定性条件、吸收边界条件。 - Based upon the forward simulation principle of ground penetrating radar , this article analyzes the realization method of the half grid spacing and the half time increment in difference format , at the same time analyzed the produce of the numerical frequency dispersion , then deduced the ideal frequency dispersion relationship and the super absorbing boundary condition
摘要本文从地质雷达正演原理著手，分析了差分格式中半空间步长与半时间步长的实现方法，同时通过分析数值频散的产生，进而推导出了理想频散关系和超吸收边界条件。 - With this method , the feasibility of project can be decided preliminarily . 3 . one - dimensional hydrodynamic model is built , in which implicit difference format ( preismann discretization scheme ) and " three steps method " of one - dimensional unsteady flow model is used , hydraulic calculation is done for water diversion and flow strengthen in tidal networks and the method is enhanced in which the precision is improved greatly
建立一维水动力学模型，利用四点隐式差分格式( preismann格式)和一维河网非恒定流模型的三级解法，对感潮河网的引水增流工程进行了水力计算并对计算方法进行了改进，大大地提高了计算的精度。
