Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): СКОРОСТЬ ЗВУКА -- РАСПЛАВЫ -- РЕДКОЗЕМЕЛЬНЫE МЕТАЛЛЫ Аннотация: The dispersion dependences of ion collective vibration frequencies are studied, and the sound velocity and isothermal compressibility are calculated. An alternative approach to calculating the sound velocity is proposed: it is based on the data on the structure of a melt Полный текст |
