如同膨缩型香肠构造一样，鱼嘴石香肠构造是存在岩石流变性差异的能干层与基质在纯剪切作用机制下形成的构造形迹。在深入研究鱼嘴构造形态与能干层基质流变性差异的基础上，运用物理模拟的方法，模拟出不同形态的鱼嘴香肠构造，反演出能干层基质粘度比与香肠形态之间的关系，进而得出一种关于鱼嘴香肠构造的经验流变计。认识到鱼嘴构造的纯剪切作用机制及其平面应变的特点，通过对香肠现有的几何参数的测量和计算以及对香肠构造演化初始阶段几何参数的恢复，在合理假设的理想状况下，推导出鱼嘴构造的应变差折射流变计。鱼嘴构造是流变行为下应变的结果，因此这种构造行迹不仅有几何学意义，更折射出流变学意义。在模拟实验与野外考察的基础上提出了一种基于流变学与剪切作用机制的鱼嘴构造分类方案。

Like pinch-and-swell structure, Fish-head boudin is another kind of structure resulting from the difference between layer and matrix taking advantage of pure shear mechanism. On the basis of the research on shape of fish-head boudin and the difference between layer and matrix, and by means of the method of physical modeling, the author modeled different shapes of fish-head boudin, and came out the relationship between shape of fish-head boudin and viscosity ratio between layer and matrix, which can be called an experience rheological gauge. Taking account of the characteristics of pure shear and plane strain, after the measurement to fish-head bodins' present shapes and the resume of their original shapes, with several reasonable and ideal presumes, the author put forward the refraction rheology gauge of fish-head boudin.
