Results: ( 1) The mean of postoperative heights of anterior and posterior vertebral body rise 44.7 centi and 2.6 centi respectively. The mean of displacement rate in sagital plane decreases 10.1%. 结果:(1)椎体前高、后高比率,术后分别平均增加44.7%、2.6%,矢状面移位率术后平均减少10.1。
Endurance experiments are done at 980 centi-degree. Test data are very discrete. 在高温980℃下进行持久寿命试验,试验结果离散性非常大。
