摘要

PROBLEM TO BE SOLVED: To estimate the temperature in a material without supposing the initial temperature in a container wall.;SOLUTION: An accurate solution is calculated by one operation by executing the following processes: the process for measuring the outer wall temperature of a material to be measured; the process for calculating the heat moving characteristic value of the material to be measured; the noise removing process for removing the noise components in the outer wall temperature measured value, which is calculated in the outer wall temperature measuring process, and in the heat moving characteristic value, which is calculated in the heat moving characteristic value calculation process, using a noise removing algorithm using a Legendre polynomials; the process for calculating the high-order differential coefficients of the outer wall temperature measured value and the heat moving characteristic value from which the noise component is removed in the noise removing process; and the calculation process for calculating an internal temperature using the high-order differential coefficient calculated in the differential coefficient calculation process.;COPYRIGHT: (C)2009,JPO&INPIT
