Combined Pitot tube and static tube that measures total and static pressure; used in aircraft to measure airspeed.

测量总压力和静态压力，把皮托管和静态管组合起来；通常用于航行器的测量。

A pitot tube is a pressure measurement instrument used to measure fluid flow velocity. The pitot tube was invented by the French engineer Henri Pitot in the early 1700s and was modified to its modern form in the mid 1800s by French scientist Henry Darcy. It is widely used to determine the airspeed of an aircraft and to measure air and gas velocities in industrial applications.

速度感应器，俗称空速管，最早就是法国工程师 Henri Pitot 先生发明，并在一个世纪后由另一位法国工程师 Henry Darcy 先生改进而成为现代形式的重要器件，广泛用于探测气体或液体的速度变化，并把数据传到给控制中心。

Shortly after the 1931 competition, an R engine using a special fuel blend powered the winning Supermarine S.6B aircraft to a new airspeed record of over 400 miles per hour (640 km/h). Continuing through the 1930s, both new and used R engines were used to achieve various land and water speed records by such racing personalities as Sir Henry Segrave, Sir Malcolm Campbell, and his son Donald; the last record was set in 1939.A 1951 R-powered water speed record attempt by Donald Campbell was unsuccessful.

在1931年比赛后不久，一台"R"发动机在使用一种特别的混合燃料做动力的情况下，使得一架获胜的休泼马林公司的S.6B飞机飞出了超过400英里1小时(640 km/h)的新记录，在随后的30年代里，崭新的和使用过的"R"发动机在亨利·西格雷夫，坎贝尔·马尔科姆爵士及他的儿子唐纳德·马尔科姆这些竞赛名人的手中创造了一系列的陆地及水面速度记录，最好记录于1939年创造，1951年唐纳德·马尔科姆尝试刷新R发动机载动的水上速度记录但没有成功。

If a 10 km/h tail wind exists, flying speed will be 30 km/h as measured by an airspeed indicator, while groundspeed will be 30+10 = 40 km/h.

而在时速十公里的顺风而空速计量测到的速度为三十公里的状态下，我们的对地速度将会是时速四十公里(30+10公里)。

We can read the descent rate as displayed on our variometer. An airspeed indicator measures our paraglider's speed.

我们可以透过升降仪来读取沈降率，空速计来读取飞行伞的空速。

The effect of deacidification was studied by the temperature, airspeed, alcohol-oil ratio and typies of the catalysts, and it taked experiments on regeneration, life and the renewable effect of deacidification of the catalyst.

本课题从温度、空速、醇油比、催化剂类型等方面对催化剂的脱酸效果作了研究，并对催化剂的再生，使用寿命，再生后的脱酸效果进行了实验。
