Abstract:Thetheory of “Final⁃statesymmetry”wasraisedbasedonthestudy of pyrophylliterheologicallaw. Itisindi⁃
cated that the structure of ultrahigh pressure cell must bepropitioustopressuretransmitting andbe ableto keep sealed.
At the sametime,inordertomeettheneedsof staticequilibrium,thefinalworkstateoftheultrahighpressurecellmust
be exactly symmetric,whiletheinitial statemight notbe symmetric. The “final⁃state symmetry” theory providesatheo⁃
retical basisfor the establishment of relationshipbetween carbideanvil andpyrophylliteblock sizeandthedesignof new
ultrahigh pressure cell structure.
