In this model, the filed is divided into many enough small grids.So we can consider one grid as a linear spatial filter (LSF), and regard the supersonic flows as the combination of many LSFs.

- 模型中劃分的網(wǎng)格足夠小，可認為一個(gè)網(wǎng)格單元是一個(gè)線(xiàn)性濾波器，最終將網(wǎng)格化的高速流場(chǎng)看作為由多個(gè)線(xiàn)性空間濾波器組成的一個(gè)空間濾波器。
