【摘要】 通过研究叶蜡石流变规律,提出了"终态对称"理论。指出超高压腔体结构应有利于传压和满足密封等条件的要求,从满足静力平衡条件出发,超高压腔体工作的初始状态可以不对称,但最终状态必须是对称的。"终态对称"理论为建立硬质合金顶锤和叶蜡石块结构尺寸配合关系以及设计新型六面顶超高压腔体结构提供了理论依据。更多还原

【Abstract】 The theory of "Final-state symmetry" was raised based on the study of pyrophyllite rheological law.It is indicated that the structure of ultrahigh pressure cell must be propitious to pressure transmitting and be able to keep sealed.At the same time,in order to meet the needs of static equilibrium,the final work state of the ultrahigh pressure cell must be exactly symmetric,while the initial state might not be symmetric.The "final-state symmetry" theory provides a theoretical basis for the establishment of relationship between carbide anvil and pyrophyllite block size and the design of new ultrahigh pressure cell structure.更多还原
