摘要：
A unit for studying isochoric thermal conductivities of solidified gases and liquids in a temperature range of 25-300 K at pressures of up to 800 MPa is described. A steady-state method of radial heat flux has been used. Temperature sensors (platinum resistance thermometers) are mounted in such a way that they are not influenced by the high pressure. To decrease axial heat fluxes, the experimental cell is equipped with protecting cylinders. The thermal conductivity of molecular crystals was measured for samples grown under pressures of up to 250 MPa produced by an auxiliary thermocompressor. The cell is blocked by cooling the gas inlet capillary with liquid hydrogen.
