TSD型杆式水平位移计的创新点在于：将减小位移传递杆摩阻力的导向轴承安装在系统保护管内，改善了位移传递杆工作状态，从而提高了系统观测精度；

The new device has the following advantages : ( 1 ) improving the working conditions of the displacement transfer rod and increasing the observation accuracy because the guide bearing that decreases the friction resistance of the displacement transfer rod is installed in the protective tube ;

结果表明，热电偶保护管密封不严，使用时环境气氛与偶丝直接接触，磷杂质污染偶丝并在偶丝晶界上形成富Pt-P脆性相，造成沿晶脆性断裂，引起热电偶失效。

The results show that the thermocouple wire was contaminated by phosphorus that came from the ambience gas , and Pt-P rich phase appeared at the grain boundary of the thermocouple wire , which caused the brittle fracture along the grain boundary , resulting in the thermocouple failure .
