本文主要用实验数据简要叙述了光纤光栅中Ｂｒａｇｇ波长随温度和应力的变化呈良好的线性关系，并介绍了一种温度补偿仪，它能有效地抑制光纤光栅的Ｂｒａｇｇ波长随温度的漂移。
In this paper, the experimental data is mainly used to briefly describe the Bragg wavelength in fiber grating with the temperature and stress changes showed a good linear relationship, and introduced a temperature compensator, which can effectively inhibit the FBG Bragg wavelength with temperature drift.
