差分算子 meaning in Chinese
finite difference operator
Examples
- Oscillation of second order difference operator
一类二阶差分算子的振动性 - Approximate difference operator
近似差分算子 - Backward difference operator
后向差分算子 - In the fourth chapter , we also propose some methods to optimize the parameters of the hybrid genetic algorithm , when used these ways in hybrid genetic algorithm ( ga + simplex ) , the results we got are much better than before
第四章针对求解第三章提出的模型问题，我们提出了差分算子，并对这个算予做了详细的测试，在这基础上提出了改进的混合遗传算法，且成功运用该算法求解了该模型。 - In the thesis , the fundamental formula of ffd method derives from the square root that is approximated by a continued fraction expansion in the one - way wave equation . optimizations of the parameters of the finite - difference operator improve the validity of the method
本论文用连分式近似单程波波动方程中的平方根导出ffd算法的基本公式，并对ffd算法中的有限差分算子进行了系数优化，进一步提高了计算的有效性。
