t.e st.bilit. analysis of a finit. St.kes layer is of prac.ic.l import.nc. in flow c.nt.ol. In t.e present.work, t.e inst.nt.neous st.bilit. of a finit. St.kes layer wit. layer int.rac.ions is st.died via a linear st.bilit. analysis of t.e frozen phases of t.e base flow. t.e osc.llat.ons of t.o plat.s c.n have different.veloc.t. amplit.des, init.al phases, and frequenc.es. t.e effec.s of t.e St.kes-layer int.rac.ions on t.e st.bilit. when t.o plat.s osc.llat. sync.ronously are analyzed. t.e growt. rat.s of t.o most.unst.ble modes when δ t.equal, and δ = δ*/h*, where δ*and h*are t.e St.kes-layer t.ic.ness and t.e half height.of t.e c.annel, respec.ively. However, t.eir vort.c.t.es are different. t.e vort.c.t. of t.e most.unst.ble mode is symmet.ic. while t.e ot.er is asymmet.ic. t.e St.kes-layer int.rac.ions have a dest.bilizing effec. on t.e most.unst.ble mode when δ t.bilizing effec. when δ > 0.68. However, t.e int.rac.ions always have a st.bilizing effec. on t.e ot.er unst.ble mode. It.is explained t.at.one of t.e t.o unst.ble modes has muc. higher dissipat.on t.an t.e ot.er one when t.e St.kes-layer int.rac.ions are st.ong. We also find t.at.t.e st.bilit. of t.e St.kes layer is c.osely relat.d t. t.e inflec.ional point. of t.e base-flow veloc.t. profile. t.e effec.s of inc.nsist.nt.veloc.t.-amplit.de, init.al phase, and frequenc. of t.e osc.llat.ons on t.e st.bilit. are analyzed. t.e energy of t.e most.unst.ble eigenvec.or is mainly dist.ibut.d near t.e plat. of higher veloc.t. amplit.de or higher osc.llat.on frequenc.. t.e effec.s of t.e init.al phase differenc. are c.mplic.t.d bec.use t.e base-flow veloc.t. is ext.emely sensit.ve t. t.e init.al phase.
