radius ratio

基本解釋

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.
數(shù)值結(jié)果表明，組成耦合器的光纖半徑比對(duì)偶模和奇模的傳播常數(shù)都有明顯的影響。
Some computational examples also show the influence of the boundary conditions on the stability of composite cylindrical shells with different long-radius ratio.
另外通過(guò)算例還探討了邊界條件對(duì)不同長(zhǎng)徑比的復(fù)合材料圓柱殼穩(wěn)定性的影響。
Calculation shows that the tension parameter depends chiefly on the balloon height to radius ratio H/R and is stable to a great extent.
計(jì)算說(shuō)明該參數(shù)主要決定于氣圈高徑比H/R，其數(shù)值在較大范圍內(nèi)比較平坦，穩(wěn)定少變。
