Analysis of pressures generated in a piston-cylinder type apparatus

摘要: Pressures generated in a piston-cylinder type apparatus have been analyzed as function of experimental path. From general consideration solid pressure media and history six characteristic P-T curve types an arbitrary specimen deduced. The observed melting is found to be dependent on maximum initial experiment cycling downward (defined herein) also convergent certain upper boundary (i.e., its true curve) when the cell used has negative anvil effect. It concluded that variation temperatures (or any other temperature or parameter) at given external bounded by physical parameter), which open bound. On basis these properties so-called method for close approximation derived. When this used, inherent strength simply obtainable by-product, can defined lower measured pressure.
