“流变”(rheology)一词来源于古代哲学家Heraclitus所说“πα′νταρ∈ι”,意即“万物皆流”。我国译为“流变”,取意“一切皆流,一切皆变”。一开始就由生产活动决定的流变力学,是根据应力、应变、时间研究物体流动与变形的构成及发展的一般规律的学科。它处于弹性力学、塑性理论和流体力学的前沿,是物理化学力学交界 The term “rheology” is derived from what ancient philosopher Heraclitus called “πα’νταρ∈ι”, which means “everything is current”. Our country translates as “changes,” meaning “everything is flowing and everything changes.” The rheological mechanics determined by production activities from the beginning is a discipline that studies the composition and development of the flow and deformation of objects according to stress, strain, and time. It is at the forefront of elasticity, plasticity theory and fluid mechanics, and is the boundary of physical chemistry and mechanics.
