摘要
本文对四阶杆振动方程提出两个半显式格式，这些格式都是绝对稳定且可显式地计算，其截断误差均为Ｏ（τ／ｈ＋τ２＋ｈ２）．
In this paper two semi-explicit schemes for solving a fourth order rod vibration equation =0 are proposed. These schemes are absolutety stable and can be cal- culated explicitly. The local truncation errors are O(τ/h+τ~2+h^2) for these schemes.
