In the temperature sensing, the theory of fiber Bragg grating temperature sensing has first been proposed, the characteristic of the FBG temperature sensing was analyzed, it was deduced that the sensitivity coefficients of first-order and second-order ,and experimental findings was protracted, the gained polynomial better inosculate with the theory value. The experiment was processed in the low temperature , the thermo-optic coefficient was emended in the polynomial of the normal temperature ,the result was accorded with the sensing character of the normal and low temperature ,and it was resolved that the theory account of the normal and low temperature did not accord with the experiment.

在温度传感方面，主要从光纤布拉格光栅的温度传感模式出发，对光纤布拉格光栅的温度传感特性进行了分析，推导出了光纤光栅的一阶与二阶温度灵敏度系数，并对实验数据进行了拟和，所得多项式和理论值吻合的很好，并对低温传感进行了实验，将在常温下得出的多项式进行了热光系数的修正，所得的结果同时符合常温与低温的传感特性，解决了低温与常温情况下的理论计算与实验的不一致性。
