| Abstract: | with the rapid development and applicaion of new thermal insultions,the guarded hot plate apparatus for the measurement of themal insultions was received more attention in fields of aerospace,chemical engineering,thermal science and architectural engineering.The recent progress on different kinds of guarded hot plate apparatus was first reviewed.The guarded hot plate apparatus operating down to liquid nitrogen temperature(-196℃) was proposed to measure the the thermal conductivities of thermal insulations,which were used for cryogenic liquid storage and transport.The design and construction of the guarded hot plate apparatus were also introduced. |
