They propose experimental investigations of wavenumber selection processes and phase dynamics in nonlinear dissipative systems driven far from equilibrium. Their work will concentrate on the rotating Couette-Taylor system with and without axial flow, but some of it will also involve Rayleigh-Benard convection. They expect the experiments to have a bearing on the general problem of pattern formation and the evolution of non-periodic phenomena in systems of significant spatial extent.

他们提出了远离平衡的非线性耗散系统中波数选择过程和相动力学的实验研究。他们的工作将集中在有轴流和无轴流的旋转Couette-Taylor系统上，但其中也会涉及Rayleigh-Benard对流。他们预计，这些实验将对图案形成和具有重要空间范围的系统中非周期现象的演变这一普遍问题产生影响。
