【Abstract】 This note has pointed out: When the initial-value is slightly changed, some computational instabilities for the ’leap-frog’ scheme and ’time-forward’ scheme in one dimensional non-linear advective equation, which is enumerated by (4), will turn into stable. Thus, the results of (2) are improved.更多还原
