摘　　要：从测量原理和实验装置上详细介绍了利用光纤光栅传感器区分测量温度和应力的两种解决方案:双波长矩阵运算法和双参量矩阵运算法。叙述了其主要工作原理,给出了图示说明,并对它们的优缺点进行了比较分析,为以后选取恰当的测量方法提供了依据。In this paper, two methods for differentiating between the strain and temperature measured by a fiber grating sensor： the dual-wavelength matrix method and the dual-parameter matrix method are presented in the aspects of measurement principle and experiment equipment. Their main operation principles are described, their diagrams are given and their advantages and disadvantages are compared with each other. Thus, the reference is provided for the selecion of proper measurement methods in the future.
