现代运动用滑翔机的机翼长而细薄，拥有最佳的空气动力学效率，其升阻比达到50：1。
A modern sports glider, with long, slender wings, is the most aerodynamically efficient aircraft, with a lift-to-drag ratio of around 50:1.
升阻比越高，飞机就能飞得更远。
And the higher the ratio, the farther the aircraft will glide.
之后，将其放入风洞以计算升阻比，有时也被称为滑翔比。
Then they popped the fish into a wind tunnel to calculate their lift-to-drag ratios, sometimes called the glide ratio.
