本文介绍了一种表面涂覆B~(**)薄膜的接触式光纤温度传感器(OFT),并从理论和实验证明这种传感器十分适用于高温燃气温度的测量。本文所进行的研究,为内燃机缸内燃气瞬态温度接触式测量打下良好的基础。
In this paper, a kind of contact optical fiber temperature sensor (OFT) coated with B ~ (**) film is introduced, and the theoretical and experimental results show that this sensor is very suitable for the measurement of high temperature gas temperature. The research carried out in this paper lays a good foundation for the transient temperature contact measurement of gas in cylinder.
