numerical filter meaning in Chinese

数值滤波
数字式滤波器

Furthermore , a numerical filter method is applied to eliminate some undesired short waves generated as the program runs , which prevents the computed results of the numerical model from distortions
在数值计算中，采用了数值过滤技术，有效地除去了由于非线性效应的相互作用而产生的极小波长谐波，保证了数值计算的准确性。
Numerical fluxes considered in the explicit portion of the algorithm were evaluated by an implicit high - order compact scheme to augment stability . meanwhile , an implicit high - order compact numerical filter was used
显式一边的空间导数采用具有较高精度和良好数值稳定性的隐式高阶紧致差分格式，同时采用适于低马赫数流动计算的隐式高阶数值过滤方法。
