【Abstract】 The measure theory and structure characteristic of FRY clothing thermal property apparatus are discussed,which developed by ourselves.The experiment data of measuring the clothing thermal resistance by the apparatus were analyzed when human body in dress.The result indicates that FRY clothing thermal property apparatus is reliable.Aiming at the amplification circuit unsteadiness,program wrong and the indirect display of the measured physical quantity,some methods were taken to improve the analog amplification and digital amplification and add the display device in pane such as adjusting the magnification,rewriting program et al. After above modification,FRY clothing thermal property apparatus has been applied to teaching ( student experiment) and scientific research and the effect is perfect.In addition,some problems that occurred in the adjusting progress were discussed.更多还原
