摘要
从理论分析和数值实例的角度详细论述了2D波场正演离散系统的记忆性、可逆性、因果性、稳定性、时不变性、线性、互联、数值色散等特征,从而全面地认识波场正演系统。分析认为,波场正演系统既有常规系统的基本特征,又有其独特的系统特征。
The characteristics, such as memorability, reversibility, causality, stability, time-invariance, linearity,series-parallel connection, numerical dispersion and so on, of 2D discrete wave field forward simulation are described respectively based on the oretical analysis and numerical examples, thus the wave field forward simulation system can be completely recognized. The analyzed results show that the system has not only the basic characteristics the conventional system has, but also has the unique characteristics to itself.
