  Two chains of Luttinger liquids coupled by both interchain hopping and
interchain interaction are investigated. A degeneracy of two kinds of dominant
states with in phase and out of phase ordering in the absence of the hopping is
removed since the transverse fluctuation of charge density is completely gapful
and that of spin density has two kinds of excitation with and without gap. The
crucial effect of the interchain hopping on the electronic properties is
studied by calculating susceptibilities.
