摘　　要：对方程u_t=au_(xxx)构造下列两层半显式差分格式PR2、RL2、CR2、CL2，其局部截断误差分别为 和 ，这些类差分格式为绝对稳定且可显式地计算．The following two level semi-explicit difference schemes are constructed for solv- ing the dispersive equation u_t=au_(xxx), P2R. R2L. C2R. C2L. The local truncation errors for the schemes P and C are 0( ) and 0( ) respectively. These chassos of the diffcrence schemes arc absolutely stable and can be caiculated explicitly.
