The formation conditions of the methanol masers in W3(OH) are studied separately. The lower limits of the densities of the A- and E-type maser regions are 105 and 106 cm−3. The A-type maser requires a stronger excitation from HII region, than the E-type maser. The relative abundance of methanol to molecular hydrogen is more than 5×10−5. The calculation indicates that there are maser series (J0-(J+1)-1) E, (J1-(J+1)0) E J=1,2 and (J2-(J+1)1) A+ J=7,8,9 in W3(OH).
