  Two modifications of the Thermally Stimulated Depolarization Current method
are proposed to improve resolution and sensitivity of the method by connecting
either a real capacitor, or an additional resistor in series with the sample.
It is shown experimentally that high sensitivity of the TSDC method with an air
gap can be obtained, if the gap is substituted by the capacitor, while all
advantages of the method remain in force. It has been found that in one
experiment it is possible not only to measure the TSD current, but also to
obtain data on the Thermally Stimulated Conductivity, if the properly selected
additional resistor is periodically switched on and off.
