摘　　要：Taking the test data in "Regulation of performance test for utility boilers"(GB10184-88) as example, the influence of uncertainty in temperature testing upon the results of measuring thermal efficiency for utility boilers has been analsyed by using the error theory. The results of analysis show, the uncertainty in temperature testing has certain influence upon the results of measuring the thermal efficiency of boilers. Hence, it is suggested that the different types of thermocouple and compensation lead wire should be used under different conditions.Taking the test data in 'Regulation of performance test for utility boilers'(GB10184-88) as example, the influence of uncertainty in temperature testing upon the results of measuring thermal efficiency for utility boilers has been analsyed by using the error theory.
