摘　　要：利用压力和温度传感器,结合单片机测量金属的线胀系数。此种方法自动化程度高,且测量结果较为精确。This paper presented a method that measure metal linear expansion coefficient by using a pressure temperature sensor and a single chip microcomputer. The automatization degree of this method was better and the result of this method was more accurate.
