摘要：

As found from enthalpimetric measurements using standard test reactions systematic errors of some percent should be taken into account in integrated circuit (IC) calorimeters. The reasons of the systematic errors are analyzed by heating of sample via several Joule heaters and laser signals at different positions. The determined positional dependence of the sensitivities which is mainly caused by the planar geometry of the heat power detector can be corrected by a shape factor. (C) 2002 Elsevier Science B.V.
