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.

当代西方新唯物主义的共识在于质疑人类中心主义预设,并要求恢复物质自身的活力。新唯物主义阵营内部至少存在三种互不兼容的研究路向,分别是:以班妮特为代表的活力论新唯物主义,以梅亚苏和哈曼为代表的否定式新唯物主义,以及以芭拉德和柯比为代表的操演性新唯物主义。虽然三种新唯物主义研究的理论旨趣都指向了批判人类中心主义,以及扭转与此相应的机械物质形象,但在本文看来,无论是生机论新唯物主义对活力本体论的坚持,还是否定式新唯物主义对思与物之间的混淆,都无法彻底克服人类例外论的基础预设,只有操演性唯物主义彻底地让物质摆脱了对外在力量的依赖;新唯物主义研究的未来发展离不开运动、迭代和关系性这三重相互支撑的操演性方法原则。
