So the US turned the YF-12 into a reconnaissance plane (the amazing SR-71 Blackbird, which remained in service through 1998 and could traverse the US coast to coast in 1 hour).
因此,美国最终把YF - 12改成了侦察机(即令人赞叹的SR- 71黑鸟。它可以在一个小时内横穿美国东西海岸,直到1998年才退役)。
Compared to the A-12, the SR-71 was larger, carried more fuel, and featured sharp sides to improve both stability and stealth.
相比a- 12,SR - 71体形更大,机载燃料更多,其具有特色的尖锐侧翼有助于提高稳定性和隐形能力。
In 1962, the first Blackbird successfully flew, and in 1966, the same year I graduated from high school, the Air Force began flying operational SR-71 missions.
1962年,黑鸟首飞成功;1966年(同年我高中毕业),美国空军在常规任务中正式启用SR - 71。
Good design is often strange. Some of the very best work has an uncanny quality: Euler's Formula, Bruegel's Hunters in the Snow, the SR-71, Lisp.
好的设计通常是奇特的.一些最杰出的作品有不可思议的品质:欧拉公式,勃鲁盖尔(Brueghel)的雪中猎人 ,SR-71, Lisp.
By contrast, the manned SR-71 Blackbird, used for many years by the U. S. Air Force, had a top speed of just more than Mach 3.
相比之下,载人的SR- 71黑鸟,供美国空军使用多年,有一个仅比3马赫以上的速度。
The contribution of RR to SR in RF (29%) was much lower than that in RP (42%, P<0.01), while the contribution of HR to SR was 71% in RF and 58% in RP.
季节雨林内根系呼吸对土壤呼吸的贡献率(29%)小于橡胶林(42%,P<0.01),而季节雨林内异养呼吸对土壤呼吸的贡献率为71%、橡胶林为58%;
