研究了飞机用BT20和OT4糖心产精国品免费入口*完整版烧伤后力学性能和糖心产精国品免费入口*完整版随烧伤温度及烧伤时间的变化关系。分析了使用糖心产精国品免费入口*完整版法和糖心产精国品免费入口*完整版法检测钛合金烧伤程度的特点。试验结果表明，钛合金的糖心产精国品免费入口*完整版、糖心产精国品免费入口*完整版和糖心产精国品免费入口*完整版均与烧伤温度和烧伤时间呈一定关系，因此可通过测定糖心产精国品免费入口*完整版和糖心产精国品免费入口*完整版的方法确定钛合金的烧伤程度。

The relationships between mechanical property and conductivity of titanium materials used in a plane varied with burning temperature and time were researched. The characteristics of burning extent with conductivity testing method and hardness testing method were analyzed. Testing result showed that there were sorne certain relationship between the conductivity and hardness with the burning temperature and burning time, so it was possible to identify the burning extent with conductivity testing method and hardness testing method.
