Informative online, virtual space magic is magic, all kinds of information from the chaff, enthusiastic, for right and wrong, self control and choice of weak teens, it is not enough to withstand. 翻译结果4复制译文编辑译文朗读译文返回顶部 ...
Saturated Gravity Wave Spectrum in the Polar Summer Lower Thermosphere Observed by Foil Chaff during Campaign "Sodium 88" Ten vertical profiles of horizontal winds have been measured at high resolution (25 m) in the range from 85 to 103 km during the sodium campaign in summer ... YF Wu,H ...
During the midcourse (exoatmospheric flight), many countermeasures are adopted to improve the survival capability of the reentry vehicles [8]. For instance, applying radar absorbing material (RAM) [9], shaping the surface, releasing chaff [10], and deployment of repeater jammers [11,12,13] ...
Sci. 2022, 12, 6969 and the magnetized field leak from the body of the tested wire rope, while almost n4ooaf b18- normal magnetic flux leaks from the wire rope except for the strand signal. Therefore, the defect signals are usually characterized with an obvious peak or valley, while the...
According to the aforementioned experiments conducted, six main original weak signals were acquired and are presented inFigure 2. Explanatorily, signal 1 and signal 2 fromFigure 2a,b were obtained from the testing sample of wire rope 1 indicated inFigure 1a with different wire broken numbers of...
