【Abstract】 This paper analyses the methods of determining the thermal conductivity of invest-ment shell mould. The hot-wire method has been conducted with an installation construc-ted by ourselves. A preliminary approach of computer simulation was carried out and a computer program to calculate has been designed.更多还原
