RESULTS: It was found that the number, size, shape, location, Angle between crown and root of all the 33 impacted teeth could be displayed accurately.
结果：上颌骨内埋伏阻生牙33颗，均能准确无误地显示出埋伏牙的方向、形态、数目、唇腭侧骨质厚度。
The crown efficiency only considers the loss in the channel of stator and rotor and the residual speed loss, clearly showing the relationship between the pneumatic angle and turbine efficiency.
轮周效率只考虑定子、转子流道中的损失、余速损失，较明显地反映了流道中气流角度与涡轮效率的关系。
