英文摘要	We calculate the binding energy of hybrid quarkonium up to the order of 1/m(Q) and find their decay constants scale like m(Q)(5/4) as m(Q) --> (infinity). The 0(--) and 0(++) hybrid quarkonium is exactly degenerate in the limit m(Q) --> (infinity), while the 1/m(Q) correction renders the 0(--) mass lower than that for 0(++). The 1(-+) and 1(+-) hybrid is nearly degenerate and lies 0.7 GeV lower than the 0--. If we use m(b) = 4.8 GeV, the mass of the 1-+ b (b) over bar g state is (10.75+/-0.20) GeV, which is the lightest exotic hybrid quarkonium. [S0556-2821(99)50315-9].
