1.At the same time, the characteristics of the LPG temperature sensing about different cladding calorescence coefficient or grating period are showed.

同时在LPG温度传感方面，讨论了不同包层材料热光系数或者不同光栅周期影响下的特性。

2.By analyzed the effects of fiber's spring, cycle flex, calorescence and the heat expand, the strain sensitivity and temperature sensitivity of FBG are obtained.

通过对光纤的弹光效应、光纤周期的伸缩、热光效应、热膨胀效应的分析得出了光纤光栅的应变灵敏度和温度灵敏度。
