cloud attenuation造句
例句與造句
- Main conclusions drawn from the analyses of calculating results are as follows : ( 1 ) the microwave absorption of atmosphere gas have obvious attenuation at the wavelengths for cloud detection , thereinto , the water attenuation effect changes greatly , so the 94ghz cloud detecting radar should have water vapor attenuation correction scheme . ( 2 ) when 37ghz and 94ghz radars detect clouds , the difference between the atmosphere and cloud attenuation and the large variety of radar reflectivity conduce the intension of the radar backscatter signals change . ( 3 ) for the thin cloud layer and low water content of cloud , 37 - ghz radar backscatter signals are not as good as 94 - ghz radar , that is to say that the 94ghz radar has better capability in thin clouds detection
本工作得出如下結論: ( 1 )大氣氣體的微波吸收在測云波段產生明顯的衰減,其中水汽衰減效應變化很大;即將上天的空間94ghz測云雷達必須有水汽衰減訂正方案; ( 2 ) 37ghz和94ghz雷達測云,由于大氣和云衰減不同和雷達反射率的很大差異,導致雷達回波信號強弱不同; ( 3 )對云層較薄、含水量較少的云,在不計雷達參數的情況下, 37ghz雷達回波信號不如94ghz測云雷達,也就是說94ghz對薄云有更強的探測能力;對云層較厚、含水量大的云,由于強衰減的作用, 94ghz雷達回波信號小于37ghz雷達; ( 4 )從大氣衰減的不利因素方面考慮,空間94ghz雷達測高層薄云的效果最好;測低層薄云時需要考慮氣體衰減訂正;因濃厚云的強衰減作用,探測其中下部的能力大大減弱,不僅要進行衰減訂正,而且要借助其他信息來反演整個云層的含水量垂直分布; ( 5 )為了獲得從極薄到極濃厚云的垂直分布探測能力,未來測云雷達系統最好采用雙波長甚至三波長(如94 、 37和13ghz ) 。 - It's difficult to find cloud attenuation in a sentence. 用cloud attenuation造句挺難的
