摘　　要：表面粘贴式光纤布拉格光栅传感器测量系统包括光纤、中间层、基体三部分。而由于三者力学性能、热力学性能的不匹配,基体的应变并不能完全传递至光纤,二者之间存在应变传递率。总结应变传递率的影响因素,并针对变温环境下的应用场景,给出了应变修正方程。The surface-mounted fiber Bragg grating sensor measurement system includes three parts:optical fiber,intermediate layer and matrix.However,due to the mismatch of mechanical properties and thermodynamic properties of the three,the strain of the matrix cannot be completely transferred to the fiber,and there is a strain transfer rate between the two.The influencing factors of strain transmissibility are summarized,and the strain correction equation is given for the application scenarios in the variable temperature environment.
