Abstract: he eliminating way was used to change the RHcompound boundary value problems to Riemann compound boundary value problems to be solved and the solution method of the nonnormal compound boundary value problems with nodes and open arcs was thus obtained, the related conditions of solvability in h(c₁,c₂,…,c_q)and the general solution were also obtained.

Key words: RH boundary value problems, discontinuous coefficient, general solution
