摘要
本文对色散方程μ_t=aμ_(xxx)构造了一类带参数的三层显式八点格式,其局部截断误差为0(τh+h^2),稳定条件为│aτ/h^3│≤3.1099。在目前尚未看到更好的结果。
A class of three-level explicit difference schemes with a parameter a for the dispersive equation ut = auxxx are established in this paper. Their truncation errors are O(τh+h2) and the stability condition is| R|≤3.1099 corresponding ??=1.283528. This is a better result at present.
