The velocity distributing, variation of extension rate, shear rate and the natural convergence angle of the fluid were analyzed under different initial entry pressure.

分析了在不同口模压力（P）下入口区速度分布、延伸应变速率、剪切应变速率以及流体自然收敛角的变化。

Conclusion: The retention of the full crowns decreased with the convergence angle increased.

结论：全冠固位力随着轴壁聚合度的增大而减小；

The more convergence angle increases, the greater dynamic pressure, static pressure and total pressure rise.

当合流角增加时，动压、静压、全压均会增大，且角度越大增幅越明显。
