透射光显微照片显示，在强剪切流下，在聚合物溶液的稳态下，旋节线分解中的域被拉长成极长的线。剪切流使管柱稳定，以克服其固有的表面张力不稳定性。弦直径随着剪切速率的增加而减小，最终变成界面厚度的数量级，导致剪切诱导的均质化。
Transmission light micrographs show that domains in spinodal decomposition are elongated into extremely long strings in steady states of a polymer solution under strong shear flow. The shear flow stabilizes the string against their intrinsic surface tension instabilities. The string diameter decreases with increase in the shear rate and ultimately becomes of the order of the interface thickness, resulting in shear-induced homogenization.
