| 1. | A snail by comparison is supersonic .
相形之下，蜗牛的爬行倒可说是超音速的了。
|
| 2. | In conclusion we note the following general items concerning flow in supersonic nozzles .
最后，我们归纳几个关于超音速喷管流动的一般原则。
|
| 3. | At supersonic speeds the control load acts mainly on the deflected surface itself, and hence has its centroid even farther to the rear .
超音速时操纵载荷主要作用在偏转面本身上，因此它的作用中心甚至更加靠后。
|
| 4. | Although strain gage balances have been most useful in transonic and supersonic tunnels, they are by no means excluded from lowspeed work .
虽然，应变天平最适用于接近音速和跨超音速风洞，但丝毫不意味着不能用于低速实验。
|
| 5. | This is, of course, the reason why a sonic boom hits us with all its fury from a supersonic aircraft but not from a subsonic one .
当然，这就是为什么音爆从超音速飞机上以它的全部力量向我们冲来，而音速飞机上则没有音爆传来。
|
| 6. | Departures form the ideal practice followed by the wright have been particularly noticeable in the development of supersonic and hypersonic vehicles .
特别值得注意的是在发展超音速和高超音速飞行器的过程中，偏离了莱特理想的工作方式。
|
| 7. | Since supersonic phenomena seldom occur naturally, the first studies of supersonic flow and flight were related to artifacts, from shells to turbines, rockets, and aircraft .
由于自然界难得产生超音速现象，所以超音速流动和飞机的早期研究同炮弹，汽轮机，火箭和飞机等人工产品有关。
