摘要：
We developed a new calibration technique for measuring the correction factor of a calorimeter with a vector network analyzer. Based on a wave-parameter formulation, we developed analytic formulas for the correction-factor (g) and effective-efficiency (eta). This allows us to calibrate both the calorimeter and the thermistor mount in a single step. This greatly reduces the number of physical parameters involved in calibration processes while tracking correlated uncertainty.
