在这里，我介绍了流变测量的基本概念和方法，特别是在超声工程领域的研究人员。尽管我们将材料视为流体并根据粘性及其代表弹性的复杂部分来表征它，但超声光谱将材料视为具有弹性的固体，这决定了超声速度。虽然这两个研究领域有着相反的观点，但它们有着共同的研究目的，即表征材料的力学性能作为频率或剪切速率的函数，并在分子水平上揭示其机理和结构。本文介绍了与超声波技术有关的流变学测量和分析的基本方法。
Here, I introduce the fundamental concept and methodology of rheology measurement especially to researchers in the field of ultrasonic engineering. Althogh we consider the material as fluid and characterize it in terms of viscosity accompanied by its complex part representing elasticity, ultrasonic spectroscopy regards the material as solid with elasticity, which determines ultrasonic velocity. Although these two research fields have contrary viewpoints, they share the purpose of the study, that is, to characterize the mechanical properties of the material as a function of frequency or shear rate and to reveal its mechanism and structure at the molecular level. In this paper, I show the basic methods of rheology measurement and analysis in relation to ultrasonic technology.
