对具有负分离比的He-3-He-4混合气体在具有实际边界条件和中等大长宽比的二维容器中的对流进行的模拟表明，在超临界Rayleigh数下，存在由无对流区隔开的“对流”，即定常对流的局域态。描述了这些态的起源和性质。
Simulations of convection in He-3-He-4 mixtures with a negative separation ratio in two-dimensional containers with realistic boundary conditions and moderately large aspect ratio reveal, at supercritical Rayleigh numbers, the existence of "convectons," i.e., localized states of stationary convection, separated by regions of no convection. The origin and properties of these states are described.
