The article theoretically calculated and analysed the assembly Stress of the pontes to proofread the allowable stress of the plate and rivets.

本文以铆钉为例,从连接所受到装配应力角度行理论计算析,校核板件与铆钉许用应力,析结构稳定性,并预测连接破坏位。

The article theoretically calculated and analysed the temperature stress of the pontes to proofread the allowable stress of the plate and rivets.

本文从连接所受到温度应力角度行理论计算析,校核板件与铆钉许用应力,析不同温度对结构稳定性影响,并预测连接破坏位。

Results The patients main signs were dizziness, vomiting, barylalia, dysbasia and hemiplegia.The focus was mainly in the middle or at the top of the pons.

结果患者以头晕、呕吐、言语不清、行走不稳及偏瘫为主要表现,病变位多在桥脑中上。

In the sagittal section of the T2-weighted image, hyperintense lesions are present in the tegmentum of the midbrain, pons, and medulla oblongata.

图B) 在T2 权重纵向截面图像，高讯号病变出现在中脑、桥脑、延脑背盖区。
