本文所做的主要工作包括以下几个内容：一、选取了常见的热膨胀系数大的材料制作封装元件，经过多次一80℃到80℃反复测试，封装元件没有出现老化开裂、封装裂纹、空洞、离层等缺陷，封装材料具有良好的温敏稳定性及复用性，与光纤相容性较好；二、对光纤光栅进行简单、实用的封装处理，就封装效果的优劣性、波长测量的准确度、重复性和封装时产生的波长损失等方面进行了一系列的实验，得出了初步的结论；三、对温敏和温度补偿式封装的实验数据进行了详细的分析和对比，从数字上对温变过程中光纤光栅中心波长的改变及温变曲线进行了定量的分析，在大量实验数据分析结果的基础上，总结出哪种材料封装效果更好，以及如何有效的减小实验误差。

Three are three major actions that Mn effects fracture behavior in the alloy at room temperature, as follow: One is that Mn fines grains, antiphase domains and weakens dislocation clog, which retain formation of cleavage crackle. The second is that Mn decreases APB energy and promotes slop and cross slip, in particular, a large number of cross slip make deformed APBs transform from line type into zigzag type and the APBs interact and cross each other, resulting in propagation of cleavage cracks. The last is that Mn raises the relative proportion of cleavage strength to grain-boundary strength and then restrains formation and propagation of cleavage crack.

Mn对合金室温断裂行为的影响主要反映在三个方面，一是Mn的存在细化晶粒和反相畴，使得位错塞积程度减小，从而阻碍解理裂纹源的生成；二是Mn的存在提高解理强度与晶界强度的相对比值，从而抑制了解理裂纹的形成和扩展；三是Mn降低反相畴界能量、促进超位错的滑移、交滑移，特别是断裂前位错大量的交滑移使形变反相畴由直线型变为折线"Z"字型，反相畴界间的相互作用、相互交错阻碍了解理裂纹的扩展。
