摘　　要：§1.引言First, a difference scheme with unconditional stability for parabolic equations of higherorder is derived. Then, the parabolic equation of higher order is decomposed into second-orderparabolic equations by a splitting procedure, and new group explicit schemes are derived. Thealternation group explicit methods are unconditionally stable. The merit of these approaches re-sults in more accurate solutions.
