| Abstract: | A computer system was set up to measure and analyse the characteristic curve of high temperature superconductor's voltage -current( V- I)by means of adjustable increment size of pulse current. The system can acquire data under the mode of automatically adjustable incremen size of pulse current, and work automatically and rapidly in data processing and analysing. Besides, this system provides real - time display and control as well as friendly user interface and easy operating; . Thus it helps to improve the comparability of critical current measured by this system with that from overseas work. |
