摘要
本文叙述了热色液晶测温技术的原理，对色度－温度关系进行了标定。并利用该技术测量了在射流撞击下的壁面温度分布。文中给出了在不同射流高度下壁面温度分布的等值线，并讨论了液晶测温技术的灵敏度及测试精度。
The principle of thermochromic liquid crystals thermography is described and thestandardization of relation between hue and temperature has been carried out. The technique has beenapplied to measure wall temperature distribution with a impinging jet. The wall temperature distributionin different impinging jet heigtht are given,as well as sensitivity and accuracy of the technology arediscussed.
