例句與造句
- Oliver(1942, 1948)has followed meteor trails to measure winds .
奧利弗（1942，1948）曾跟蹤流星尾跡測(cè)量風(fēng)。 - Oliver ( 1942 , 1948 ) has followed meteor trails to measure winds
奧利弗（ 1942 ， 1948 ）曾跟蹤流星尾跡測(cè)量風(fēng)。 - Furthermore , meteor trails scattering can affect the performance of a beyond - light - of - sight radar system
最后研究了流星余跡散射對(duì)超視距雷達(dá)性能的影響。 - In this paper the essential characteristics of meteor trails and the reflection and propagation from meteor trails are studied
以圓柱形的電子云為例，研究了欠密類和過(guò)密類余跡散射特性。 - When radio waves pass through half of the first jump distance , the effects of meteor trails scattering on a radar system are investigated
計(jì)算了電波經(jīng)電離層跳躍前進(jìn)的過(guò)程中，流星余跡散射對(duì)后向散射超視距雷達(dá)系統(tǒng)性能如作用距離和發(fā)現(xiàn)概率等的影響。 - It's difficult to find meteor trail in a sentence. 用meteor trail造句挺難的
- Shooting can stop as soon as a bright meteor appears . since the endpoints of the meteor trail and the star trails are captured simultaneously , this helps us identify the meteors exact location and the meteor shower to which it belongs
攝影時(shí)，若有明亮流星經(jīng)過(guò)拍攝天空，可立即停止攝影，這樣流星跡與恒星流跡的最后一點(diǎn)是在同一時(shí)間攝得，便可較易辨別其位置，并確定屬于那一流星雨。 - The effects of meteor trails scattering on a back scattering beyond - light - of - sight radar detected distance and probability of detection are creatively calculated in theory . it is practicable worth for analyzing the performance of the electronic systems
本文第一次從理論上研究了流星余跡散射對(duì)電子系統(tǒng)性能影響，這些結(jié)果對(duì)研究突發(fā)通信系統(tǒng)和超視距雷達(dá)系統(tǒng)等電子系統(tǒng)的性能都有一定實(shí)用價(jià)值。 - The effects of the meteor trails orientation on the size and shape of the footprint on the ground are calculated , which the mechanism of good concealment , antijam and low probability of intercept is explained . this method overcomes the classical limitation
其次用數(shù)學(xué)的方法研究并計(jì)算了流星余跡的方位對(duì)地面“足跡”的形狀和大小的影響，從而揭示了流星突發(fā)通信具有保密性好、抗干擾性、抗攔截的物理機(jī)制，克服了經(jīng)典方法的缺陷。
