Then they popped the fish into a wind tunnel to calculate their lift-to-drag ratios, sometimes called the glide ratio.

之后，将其放入风洞以计算升阻比，有时也被称为滑翔比。

But the new study shows that the ratio of oxygen and nitrogen isotopes found in the solar wind is different from the ratio here on earth, or on the moon or Mars.

不过这一最新的研究发现，太阳风当中的氧和氮同位素比例与地球、月球或火星上的比例不同。

There appears some flexibility at the top of tower with high ratio of height to diameter (H/D), caused by wind load.

高径比（H/D）较大的塔在风载荷的作用下，在塔顶处会引起一定的静挠度。

Only 115, 000 women have committed crimes worthy of jail -- and while that's doubled in the last 10 years, more men continue to wind up in jail by a ratio of nearly 15-to-1.
