radius ratio

基本解释

Numerical result shows that the propagation constants of even and odd modes are obviously affected by the radius ratio of the two fibers composing the coupler.
数值结果表明，组成耦合器的光纤半径比对偶模和奇模的传播常数都有明显的影响。
Some computational examples also show the influence of the boundary conditions on the stability of composite cylindrical shells with different long-radius ratio.
另外通过算例还探讨了边界条件对不同长径比的复合材料圆柱壳稳定性的影响。
Calculation shows that the tension parameter depends chiefly on the balloon height to radius ratio H/R and is stable to a great extent.
计算说明该参数主要决定于气圈高径比H/R，其数值在较大范围内比较平坦，稳定少变。
