辩证唯物主义认为,真理是客观的,同时又是绝对和相对的统一。从认识真理的过程来看,真理是一个从相对走向绝对的逐步深化的过程。任何物理概念和理论都不可能是绝对完善和一成不变的。当实验提供的经验材料同旧理论发生矛盾时,客观上要求人们去更改和变革旧理论;当物理学的基础和它的研究模式还能够容纳不断增长的实验事实时,只须对旧理 Dialectical materialism holds that the truth is objective and at the same time an absolute and relative unity. From the process of understanding truth, truth is a process of gradual deepening from relative to absolute. No physical concept or theory can be absolutely perfect and immutable. When the empirical data provided by the experiment contradicts the old theory, it is objectively required that people should change and change the old theory. When the basis of physics and its research model are able to accommodate ever-increasing experimental facts,
