摘要：
An infrared radiation pyrometer for transient temperature measurement and a photoelectric installation for micrometric length-change measurement were developed. After being heated by a CO2 laser pulse of 0.1-mu-s, the transient temperature-rise history and length change of thermal expansion of 20-50-mu-m Al films during tens of microseconds were recorded. Nonsynchronous change of temperature and thermal expansion under transient heating was observed.
