材料低温电阻的微机测试系统

文中提出的材料低温电阵的微机测试系统，具有采集数据快，同时进行多点测温等特点。当在数据采集足够快时，可忽略样品温度漂移的影响，从而提高了测量的速度和精度。 

Microcomputer System for Measuring Low Temperature Resistance

A system for measuring low temperature resistance is fabricated by using microcomputer. It has the advantage of collecting data quickly and being able to carry out the temperatures of many points simultaneously. Owing to its fast data collection, it is possible to neglect the influence of the temperature drift, thus improving the speed and the precision of the measurement.
