数值计算采用了有限差分法，可算出某时刻厚板边缘散射场的分布和某点声场随时间的变化。
The finite difference method (FDM) is used in the numerical calculation. Fielddistribution at particular time and field at one point as a function of time are displayed.
荷伯先生认为，大部分的非洲城市就像一个单煎荷包蛋，贫民区与富民区都异常整齐的分开，贫民区从城市边缘散射开来。
Most African cities separate fairly neatly into poor and rich areas "like a sunny-side-up egg", with slums spreading out from the rim, says Mr Hebel.
这次模拟器没有对表面行波、相邻边界和缝隙的反向散射，或者边缘绕射散射效应进行建模。
At this time the simulator does not implement surface travelling wave modelling and associated edge or gap backscatter modelling, or edge diffraction scattering effect modelling.
