摘要：

We studied the n-value (V proportional to I-n) and second derivative (d(2)V/dI(2)) of the voltage-current curve of high and low temperature superconductors and superconductor simulators. We used these parameters for diagnosing problems with sample heating and data acquisition, and as indicators of the superconducting-to-normal state transition. The superconductor simulator may be useful in testing the measurement system integrity and reducing measurement variability since its characteristics are highly repeatable.
