收集了两相间可能发生剪切相变的“相图”。在两相共同应变率和共同应力的条件下，我们考虑了剪切增稠和剪切变稀流体，给出了四种基本剪应力-应变速率曲线，并讨论了它们的浓度依赖性。我们概述了如何构建更复杂的相图，讨论了各种实验体系属于哪一类，并概述了如何根据流变学测量重建相图。
The possible "phase diagrams" for shear-induced phase transitions between two phases are collected. We consider shear-thickening and shear-thinning fluids, under conditions of both common strain rate and common stress in the two phases, and present the four fundamental shear stress vs. strain rate curves and discuss their concentration dependence. We outline how to construct more complicated phase diagrams, discuss in which class various experimental systems fall, and sketch how to reconstruct the phase diagrams from rheological measurements.
