| Abstract: | This paper introduces a new way to measure the conductance. We adopt rectangular wave to measure and sampling at special spots. At same time, we can keep the temperature stable by the semiconductor caloristat. By this means, the error caused by the capacitance of cable and polari-zation in measuring conductance can be efficiently decreased, and cons-equently raising the accuracy of measurement to a higher quantity level. |
