摘　　要：针对合金受激冷却温度场的特点,提出了基于光纤测温原理的测试方案;介绍了测试系统的构造,并与原有热电偶测试系统进行比较;在测试精度、响应速度、适应性、成本等方面均优于热电偶。A new method using optical fiber based on its characteristics to measure chilled temperature field in alloy melts is proposed. The measurement system has been＇designed based on optical fiber conduct technology and is presented in this paper. The performance of optical fiber measurement of temperature field is better than that of thermocouple in many aspects such as precision, response time, applicability and cost.
