高斯投影坐标换带和子午线收敛角计算编程

The natural convergence angle also augments with the rising of initial entry pressure, the corresponding natural convergence angles are 85 °, 90 ° and 105 °.

入口自然收敛角也随着P的增大而增大，相应的入口自然收敛角分别为85°，90°，105°。

Increased convergence angle did not obviously increase fracture strength of the dentin-bonded IPS Empress 2 all-ceramic crown.

牙体轴壁聚合度的增大并不能显著提高采用粘结系统粘结的全瓷冠的抗压强度。

The result shows that the die swell ratio of two fluids changes a little, as the convergence angle ranges between 0 ° and 30 °.

结果表明：当流道收敛角α在0°~30°区间变化时，角度的大小对两种熔体的挤出胀大率均有一定的影响；

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。

Methods Using FC and conventional Doppler echocardiography ( DE) methods, the effective regurgitant orifice area ( ERO) was calculated in 48 patients with isolated aortic regurgitation and a flat proximal flow convergence angle.

方法选择近端血流会聚角呈水平型的单纯性主动脉瓣反流患者48例，分别应用血流会聚法和常规多普勒超声法测量有效反流口面积（ERO）。
