We investigate low-energy properties of a generalized spin ladder model with both of the spinalternation and the bond alternation, which allows LIS to systematically study not only laddersystems btrt also alternating spin chains. By exploiting non-linear o model techniques we stvndythe model with particular emphasis on the competition between gapfttl and gapless states. Otrrapproach turns out to provide a tnore consistent semi-classical description of alternating spinchains than that in the previous work. We also sttrdy a closely related model, i.e., a spinchain with plaquette structtrre, and show that frttstration causes little effect on its low-energyproperties so far as the strength of frustration is weaker than a certain critical value.
