Na osnove molekulyarno-dinamicheskogo modelirovaniya s pomoshch"yu poluempiricheskikh potentsialov mezhatomnogo vzaimodeystviya Stillindzhera-Vebera, EDIP, Tersova i ikh modifikatsiy, predlozhennykh za poslednie 30 let, provedyen sravnitel"nyy analiz mekhanicheskikh, teplofizicheskikh kharakteristik, kharakteristik fazovogo perekhoda v shirokom diapazone temperatur i davleniy i kriticheskikh parametrov dlya kremniya. Vydeleny potentsialy, naibolee priemlemye dlya modelirovaniya kristallicheskogo kremniya, fazovykh perekhodov i kremniya vblizi kriticheskogo sostoyaniya, predlozhena algebraicheskaya kombinatsiya dvukh potentsialov, dayushchaya luchshie rezul"taty pri modelirovanii. Opredeleny temperaturnye zavisimosti teployemkostey i koeffitsientov ob"yemnogo rasshireniya, zavisimosti izotermicheskoy szhimaemosti, temperatury i teploty plavleniya ot davleniya, a takzhe kriticheskie temperatura, plotnost" i davlenie dlya kremniya.
